This was like a small project where we have to use oops concept to build this game and pass the given test cases.There were 4 test cases and time of 8 hr was given to solve this problem. I started to code the problem in CPP and it took me around 3 hrs to understand the question code the solution. Even after 3 hrs I was able to pass the 3 test cases out of 4 so I took around 1 more hour to debug the code and get the 4th test case pass.
They took 10-15 days to announce the result of round 1 , they might have gone through the codes to check the plagiarism and oops concepts used. They shortlisted only 3 students for the next round.
Round 2: Technical Interview 1(1 hr)
It was a virtual interview with a Senior Software Engineer. I was asked the following questions:
Overall take away from the interview is that , study your resume properly , most of the questions will be based on that.
Round 3: Technical Interview 2 (30 min)
It was also a virtual interview with a manager . This interview was just to make a technical conversation with a manager so that he gets to know about my technical skills more. Again most of the questions were based on my resume so basically they tested that I have not lied in my resume . Questions on Database, REST API , Django, and core CS fundamental were asked. Also one easy DSA question was asked with code which was just like a formality question.

All the very best to everyone
It consists of 15 mcqs related to quantitative and logical reasoning, another 15 mcqs on CS core subjects like DSA, SQL, OS, JAVA, etc.
And consists of one coding question (Not same for all). Coding question difficulty level was leetcode medium, related to array, sorting, greedy. Overall apti difficulty was easy - medium level.
Started with a formal introduction. Then 2 DSA question, first on linked list, and another on queue. 1st question link (you are not given number of nodes. and interviewer wanted two pointer solution in one pass)
Then they shifted to SQL. asked me query to get highest salary of an employee department wise, also without using aggregate function and more questions based on same schema. Then from OS, they asked about multithreading, have you written any code on multithreading and how? Data structures used in OS, etc. What actually happens when you run a program (in detail).
From Project, they asked concepts related to NodeJS, api calls, restful api, different methods, and gave one scenario and asked me to design an api for that. From OOPS, gave me code and asked me to predict the output (which constructors will get called). concept of virtualization, etc. Basic questions about C++.
I mentioned about Cloud Computing in my resume. so they asked me why there is need of cloud? basic services. and asked me by which means I can ensure security of my data while using cloud? Some non-technical questions, scenarios related to work life challenges, etc. Overall it was a good experience, they were more interested to know my approach and my knowledge about particular subject rather than exact answer.
It lasted for 20 minutes. Mostly based on what projects you have done, what features can be added extra, i.e deeper discussion on my projects. simple array and hashmap question. asked me what is my favourite subject? real-life example where stack is used (not related to any computer system, he wanted example from day-to-day life). Why normalization is needed? Advantages and disadvantages of normalization. C++ VS Java.
How was your day. Why you want to join UBS. Family background. What you learned in 21 years of your life? cross questions on my answer. Role of data in this world. How is data different from information. Define in one line, how data is important for UBS. About my hobbies. Are you ready to relocate to pune, and all general questions.
My overall experience was great. Just let interviewer know what you're thinking, what's your approach. Be confident. And be carefull about what things you mentioned in your resume.

I had only 2 technical interviews and I was selected,but for some of my friends they took 3-4 interviews
There were total of 3 rounds.
Round 1: Aptitude
20 MCQs which included SQL, OS,C,C++ and 2 coding questions

2. The Missing Prisoner Prisoners are standing on a Cartesian coordinate system present inside a jail. Each prisoner stands at a unique point with both the coordinates (x,y) being integers. Each prisoner should be at a position that forms a rectangle or square with 3 other prisoners. More formally, every prisoner at a coordinates pair [x, y] should have: at least one prisoner standing at integer coordinates (x. ay) where ay != y. at least one prisoner standing at integer coordinates [bx, y] where bx != x. Unfortunately, one prisoner has escaped. Find the coordinates of that prisoner. Example locations = [[1, 1], [1, 2], (2, 1)] [4. 4), (4, 6], [9. 4). [98]]
Round 2: Interview
DSA questions
Name: Mayur Kamble
Company: Forcescout Technologies
CTC: 11LPA + 15L (Medical Insurance/year)
Total Rounds: 5 (1Apti + 2 Technical Interview + 1 Managerial Round + 1HR)
Whenever Forcescout come for drive be prepared with java and DB,
In java Main focus should be on
Aptitude Test:
2 Coding questions (Easy and Medium) + Easy MCQ’s based on computer fundamentals (OS, DB, DSA)
1st Interview: Technical
Duration: 1hour+15min
Two people were taking my interview they asked me to introduce myself. I started my introduction it was around 1-2min long. In my introduction I mentioned that I got 5 stars
In java on hackerrank. I mentioned it intentionally because I had talked to one of our seniors who is in Forcescout so he told, the main tech stack of the company is java and they want java developers. After my introduction he asked me how much you rate your self in java I told him 4/5 and he was happy with it.
Then he started asking questions in java,
1)Explain pillars of oops in java
2)How will you achieve abstraction in java?
3) Difference between abstract class and interface?
4) When you will use abstract class and when interface?
5) What is the advantage of interface over class?
6) What is clone method in object class?
7) Explain internal implementation of HashMap in java?
8) Do you know multithreading in java?
9) What are the methods to achieve multithreading in java?
10) Write the code on paper to achieve multithreading by using both methods?
11) Then questions were asked on the code which I had written.
12) What is run method in multithreading?
13) Then questions were asked on Exception handling in java.
14) He wrote a code on paper an asked me about output. The question was on exception handling. Simply on try catch and finally block.
15) He wrote return 0 statement in try block and asked me weather the finally block will execute or not? Answer was YES.
16) The he asked me how to stop this execution of finally block?
I told we can avoid it by writing System.exit() .
17) He gave a String question and told to write a code on paper language was optional
Question was
Input = “My name is Mayur” Output= “ru yaMs ie manyM”
I told him simply a two pointer approach he was happy with it.
18) Then he asked me do you know DSA
I told him yes
Then he asked can we go in tree data structure
I told him yes you can. So, he asked what is mirror tree?
I draw a diagram and explained to him. He said OK know write a code to convert the tree into mirror tree. I had solved a similar standered question to check the give tree is mirror tree or not. At first, I took a time around 2min to think then one recursive approach came in my mind I wrote the code and he said ok.
19) Then he asked which DS you will chose for level order traversal of the tree
I told Queue, then he said take a sample example and do dry run for it.
20) Questions on views in SQL
What are views? Write a query for view.
Then he asked me do you have any questions?
Then I asked some questions he then extended the conversation.
When interviewer asks such question try to show your interest in the company by asking questions, do some research about company before going for interview.
2nd Interview: Technical
Duration: 1hour
In this interview also two people were taking the interview but they were different from the previous one. He asked me to introduce myself. He then went on DBMS questions.
Told me to design a schema for a glossary store, where from the bill number we can retrieve all the details of the order. A long discussion went on that topic.
Then he asked me what is API. I explained him about Apis, then he told me whenever we are using APIs our data is coming slowly so design a cache for it.
So, I told an approach by using HashMap, then he gave me one condition if the particular request is made for 5 times, then only store it in cache how will you get it?
I took a time then I said we make one local cache where we store a count for that request and if it is greater than 5 then only, we store it in main cache and retrieve it from there other wise we bring the data from our server.
He added one more condition to it, if a request is stored in our cache and no call for that request is made for 5min or more then we should remove it from the cache.
I was thinking about it and he gave me a hint he told to think about threads then I realized and told him we will run a daemon thread for every 5min and check for it. He was happy with it. He gave one more question on string given a string and you have to print word with length of the word in that string and he told me to write code on paper in java only.
Then I wrote the code and he asked me do you have any questions?
I had prepared some questions for this and I asked them.
3rd Interview: Managerial
Duration: 15mins
Just normal questions what was your project, how many members were in your team? how you divided the work? what was your work? ,from where you are
And then he started explaining about companies after that he asked do you have any questions and the interview were ended.
4th Interview: HR
Duration: 30mins
It was a group interview between HR and we 5. Just normal questions about how was the interview experience, family background, your motivation about education and all.
Tips:
Whenever a company visits to our college start researching about company talk with our seniors who are in that company about their interview experience, and hiring procedure.
Also talk with your other college friends where this company have already visited because most of all time company asks same questions in aptitude so it will be helpful to you.
Make your basics clear, also keep regular practice of coding.
During placement season you will feel depressed, stressful, you will get many rejections in interviews, most of the time at the starting of placements you may not clear any aptitude tests, your close friends will get placed so self-doubts will arrive in your mind but you don’t have to lose your confidence, continue your preparation at the end there is something for you……
ALL THE BEST FOR YOUR PLACEMETS…………………….
So, we had 3 campuses on the same day. Forescout, NICE and Emerson. I was shortlisted for Emerson and NICE.
The Aptitude test for NICE was conducted a day earlier, which consisted of multiple sections:
General Aptitude
Core Java
DBMS
Operating Systems
And 2 coding questions. For me, both were simple coding questions based on arrays. I was lucky to get them, some people got questions of graphs, so be prepared. PPT and interview were scheduled the next day. There were 2 rounds. One technical, one technical + HR. 46 students were shortlisted for Interviews.
Immediately after the PPT, I was one of the first to go for the technical round. Actually I was not expecting for my round to be so early, and was way too nervous to appear for the round. The interviewer noticed it, offered me some water to drink and tried to calm me down by asking some general questions.
Technical Round:
Moving on to the technical, he was the senior frontend developer. And fortunately or unfortunately, our tech stacks were poles apart. I had no projects on web technologies, I had 2 in ML, one in android and one in DBMS. So, he was not that much interested into projects. He just asked me to explain them in brief.
In DBMS, he asked me to write a query to join 3 tables.
He asked about android studio, build.gradle, I didn't know much about it, but I told him how the code is compiled and how the apk file is formed. He wanted to ask about java, but I told him that I did the project by watching some YouTube videos, I knew only basics of Java and he started laughing. But still, he asked a few basic questions about Java, like what is public static void main?
Then, he moved on to python, since I had it in my resume, he asked a few data structures in python like set, list and list comprehension. I didn't know about list comprehension either. Although later I found out that I had used it previously, I was just not familiar with the term.
Next, he went on to OOPs and this is where the interview changed. In OOPs, he covered everything. No stone was left unturned, from classes and objects, to virtual functions, virtual destructors, he asked me everything. And I answered everything correctly. Interview lasted for about 1 - 1.25 hrs
But still, I was not much confident as my interview spanned double the time of others, and I was a bit nervous during it as well. But I was one of the first ones to get shortlisted for the HR round. So, be strong in one of the core aspects, if the tech stack of you and your interviewer does not match, the interview can be diverted to one of your technical skills / core subjects.
Technical + HR:
For the HR round, there was a panel of 2 members. One was the director of Engineering and the other was the Senior HR manager. Initially, they asked me to introduce myself. And from there on, they began to ask about the projects. They asked me to list down the requirements to design an application for the IT CCF (related to my project).
Then they asked about what was my main aim in my career? For me, I said it was to become a data scientist. So, they began asking questions regarding data science, like why do I want to become a data scientist? What is the difference between data science and machine learning? Will chatgpt replace data scientists? In which sector do I want to work with data science?
Then they asked me a tricky one, like if you want to estimate the number of cancer patients in a district, what will be the high level data that you'll require? They were just checking my thought process, there was no right or wrong answer.
Since I mentioned writing, making cricket videos in my resume, they asked me that how do I use data in making these videos?
They also asked what about my video editing career if I get selected? To which I replied that it's not a career and all 3 of us shared a laugh.
Then they asked about the things that I have achieved in technical, non-technical and academics and of which I am proud of.
And then finally, they asked me what I knew about NICE and whether I have any questions for them. I asked about how was their experience working with NICE, and what should I do to make the most out of my Final Year?
I was way more confident in HR than in technical, and it was really nice experience interacting with such senior personnel.
This round too lasted for about an hour or more.
Tips:
Focus on OOPs, seriously, if your OOPs is weak, it gets way more difficult for the interviewer to ask you questions.
If you don't know the answer to any question, try answering something related to it, don't directly say no especially if it is mentioned in your resume.
Work on some unique non-tech skill, learn something new about what you're passionate about. So you'll at least have something else to talk about rather than just technical areas. Both of the interviewers seemed impressed a little bit when I mentioned about script writing and video editing skills.
I don't know who needs to read this, but many of you might be going through a lot. Maybe all of your roommates are placed. Maybe you've been rejected by 5 companies. All you got to do, is just hang in there. Keep trying and finally your time will come. I was the last one to get placed in my room, and in the end, it didn't even matter. Writing this seems easy, but going through it has been rough, and now I know, that times like these do pass, if you're having one, it shall pass too. Trust Yourself, if you can pass in ESE just by studying a night earlier, you can definitely crack a bunch of interviews. It's just a matter of time, you will get there. And finally to quote Steve Jobs, "Stay Hungry, Stay Foolish". Best Of Luck!!
The test was relatively short, consisting of 5 to 6 sections: aptitude, C fundamentals, OOPs, code snippets, programming, and AI or statistics.
Each section had a maximum of 5 questions. The aptitude section's difficulty depended on individual proficiency. There were 2 easy programming questions. The OOPs and fundamentals questions were of medium difficulty. The code snippets section presented some tricky challenges. Although I wasn't prepared for the AI section, it involved simple statistics under heavy AI terminology, manageable if you grasped the question context.
I don't remember the exact time given for the test, but it was around 1.5 hours. To secure selection, it was essential to answer almost all questions correctly. Many students had only 1 or 2 questions wrong and were confident, yet only 6 were shortlisted.
The selection announcements were made several days after the test. Interviews were scheduled for the next day after the announcement, leaving very little time to prepare.
The interview was conducted online, with 2 or 3 interviewers present: one for introductions, one to handle technical questions, and a manager. The interview lasted above 1 hour, the technical part being the longest. The interview commenced with a basic introduction. It's crucial to prepare your introduction well and maintain a clean resume. Avoid listing skills you haven't used or are less confident about, just to inflate your resume. After my introduction, about 5 minutes into the interview, they went point by point according to my intro/resume, deeply into the skills I mentioned. Be cautious about what you emphasize while speaking. After 1 or 2 questions, I realized they were asking progressively deeper questions about the topics I sounded confident about. So, from the next questions, I started speaking boldly about the topics I wanted to be asked about. It worked for me, as they began asking questions on the subjects I had emphasized. The interview lasted around 30 to 35 minutes. Then, the interviewer asked me to open Notepad and write code while sharing my screen. The questions were basic, such as declaring an array, printing the nth element, finding the nth largest/smallest element, and some questions from the aptitude test. You could use any programming language for this part. When the interviewer indicated no more technical questions, the managerial round began with another person. This conversation was more general. They aimed to understand your behaviour, so rather be yourself than being goody-goody. The interview results were announced after a few days.
I had one interview, but many had two or even three interviews. Feel free to ask any other help if required. All the Best👍🏻👍🏻!
Coding Test: 30 mins: The question was pretty simple and straightforward i.e to generate three random numbers and if the sum exceeds 100 then print lose, if the square root of the second and third numbers is equal to the second number then print win, if the sum of the second and third numbers is less than c, print lose.
PS: The motive was to analyze how well-indented, efficient code with proper comments one can write.
Round 2(Technical interview-45 mins):
Round 3 (Coding interview -20 mins): It was a short round where the interviewer asked me to introduce myself and then he dived into the actual interview part where he asked me to write code to add two numbers without using any arithmetic operators after that, he asked about my preferences on which tech stack I want to work.
Round 3(HR round-20 mins):
PS: Don't just rely on one company , be ready with your backup plan :)
Deutsche Bank came to our campus on 16th July for Online Coding round followed by 4 Interview Rounds on 20th July.

What will you do if one of your colleague isn't working?
What will you do if you've arguments with making a decisions on a project?
Finally 15 students including me were selected for the Deutsche Bank Grad Offer.
TIPS:
1. Be confident and have a smile on your face, even if you failed to give the answer.
2. Try to communicate with the interviewer, ask doubts, they may give you wrong information and expect you to ask.
3. Discuss your approach while solving problem and ask for hints if you need.
4. Be ready with some examples supporting your answer.
5. Be ready for the common questions that can be asked on your projects.
ALL THE BEST
Veritas Came on campus on 24/07/2023. It was a total one-day process with online interviews on teams.
Aptitude Test (Time Duration - 1hr - Hackerrank Platform) :
The aptitude test consisted of 20 MCQ(easy) and 2 coding questions (medium + hard ). For some of the people, they had 20 MCQs (easy) and 1 coding question(easy) + 1 SQL query (very hard).
MCQ were just normal questions from OOPs, C++, DBMS, OS, and CN. If you have a little basic understanding as well, then also you will be able to clear MCQs.
Everyone had a different set of questions for coding. For me, it was one question on finding analogous arrays https://aonecode.com/Interview-Question/Count-Analogous-Arrays#:~:text=Two%20arrays%20are%20analogy%20if,%2C%203%2C%20%2D3%5D. and one on graph
I had solved analogous arrays partially (6/15) test cases passed, and graph all test cases passed(10/10). Those who had cleared at least more than one were selected for interviews.
Technical Round : (Time Duration - 1hr - 1:15 hr , Shortlisted for this round - 20)
First, they asked to introduce yourself, then they asked to describe about college journey till now in terms of learning technology. Later he asked for preference of coding language . I had told them C++.
Managerial Round (Time Duration - 45 min -1hr ,Shortlisted for this round - 8)
In the end , I was selected 😁 (Total candidates selected - 3)
Tip : Try to find out if company had visited any colleges just before coming to your college . And try to get all the questions from them (use your network like Linkedin) , specially aptitude , In my case they were totally same MCQs, coding questions.
I recently got placed at IdeaS A SAS company through campus placement drive, here is my interview experience
The process consisted of total 3 rounds and the drive was conducted for 2 days
Round 1: Aptitude
There were 25 mcqs with 5 different sections each consisting of 5 mcqs
Make sure that you attempt every ques seriously as these questions too are considered during evaluation long with coding questions.
There were 2 problems from problem solving section where we were supposed to write the answer with it's explanation.
The last one was a coding question of easy level.
The whole aptitude round was conducted on Reliscore platform.
A total of 22 students were shortlisted for next round for software engineer role.
Round 2: Technical interview
This round lasted for about 1 hour.
Was a very generic interview, it was a panel a 2 people. They asked questions on almost everything that I mentioned in the resume.
Some of the questions are.....
1. Brief intro about myself.
2. What is your favourite subject? I said OS
3. What is swap space?
4. What is MBR?
5. How does file system work?
6. What is indexing?
7. What is partitioning?
8. How will you remove duplicates from an array?
9. Write a code for merge sort.
10. How did you store images in your MERN stack project?
11. On what part of the project you worked upon?
12. What is an image in Docker?
13. What is containerisation?
14. Write a Dockerfile for nodejs project.
15. A puzzle.....There are 10 different coins each of denomination from 1 to 10 each weighs different, coin 1 weighs 1 gram, coin 2 weighs 2 grams, ........coin 10 weighs 10 grams. One of denominanations coin is defective and we to have to find that defective denomination in 1 weight using balance.
16. Any questions from myside?.......I asked about their role in company and any suggestions for my improvement.
Tips:
1. I didn't know the solution for puzzle but I tried. I asked for hint but they didn't give that too. My solution was not perfect but I still made sure that I at least try.
2. Be calm, confident and talkative. They are more interested in the way you approach a particular problem.
A total 7 students got shortlisted for next round
Round 3: Managerial + HR
This round lasted for about 1.5 hours and honestly felt more difficult than the technical one. The interviewers were very experienced and clever.
They started with the utility of my project, whether it is deployed or not........In my case it was deployed which I think gave me an edge over others.
Some non-tech cross questions on my project .
Favourite subjects from academics and why?
After this there were more of a behavioural questions which are very much situation based
1. Who is role model?
2. What are your aspirations?
3. Where do you see yourself after 5 years?
4. Are there any plans for higher education?
5. Apart from academics your favourite subject?
6. Do you have interest in politics?
7. The thing that you learnt on your own?
8. The decision that you took that you are most proud of?
9. The decision that you took that you are most ashamed of?
10. How will you deal with people?
Tips:
1. Soft skills and fluent English speaking helped a lot in this round/
2. They were just expecting honest answers from my side.
Finally they hired 4 students for FTE as SDE and 3 interns whose PPO will be performance based. I got a FTE offer!!!
2. Coding questions
1.MCQ were based on core subjects and OOPS. There were around 30 MCQ questions. Difficulty level of questions were from easy to moderate. Time will be the main constraint for cracking this stage. You have to give correct answers of minimum 75%-80% MCQs for making your chance to qualify for interview a bit stronger.
2. DSA question were basic, but were application based, there are no straight forward questions as you practice in any of the sheets. You have to use the concept of questions you solved previously in such application based questions. There were three coding questions and you have to solve atleast 2 questions completely and last question must have atleast 50 % test cases passed. Array, string, stack, queue were on main focus.

All the best everyone!!
Online Assessment:
A). 20 MCQ questions on the core subjects
B). 2 coding questions, one was on string and second on dp
Round 1: (Technical round)
It was a technical round. It started with an introduction. He asked me about my language preference and to open any code editor.
He started the round with introduction and moved on to cpp. He asked me to implement all oops concepts.
Then he asked me about error handling and also to implement the error handling in cpp.
There were questions regarding working of cpp language and compiler.
Later he moved on DSA part. He started with basic data structure questions.
After testing my DSA, he moved on to DBMS and asked a few basic questions such as what is DBMS? What is the difference between an SQL database and a NoSQL database? All the questions were so basic.
There were some questions on string also.
In last he asked me about my project and internship and asked some counter questions on internship project.
Round 2: (Hiring Manger round)
It started with my introduction and then She asked me about my project, internship, my all experience, club position.
Then he asked me one puzzle. It was based on binary search. I told him many the ans. But asked me more efficient and and to optimise the ans to reduce the steps.
He asked me about my future goal and education.
I told him currently there no plan for PG.
Then he asked me counter questions on my ans. But I was stick to my ans.
Round 3: (HR Round)
It was quite an easy round and asked me about me and who took my interviews. Later he asked how many employees work in Veritas, he was just checking If I attended PPT sincerely or not. Then he moved on to discuss the salary structure.
In last I asked one question to him.
Tips:
1) Prepare DSA and Core subjects basics so well.
2) Always remember if interviewer asked if you have any questions? Then this is big opportunity. Don't miss this opportunity.
3)Don not panic at the time of interview.
4)You clear communication is always plus point.
First Aptitude + Coding Test (75 minutes):
(All branches were allowed for this round)
It was conducted online on a platform called Mettl. The test consisted of 3 sections (Quant + Reasoning + logic, Data interpretation, Coding) the total test was of 75 minutes important thing to note was there was a negative marking as well. The sections can’t be switched so the sections need to be solved individually. The first section contained 10 questions and the level was easy. The second section had 6 questions, 3 for each given data set in terms of chart/graph/etc. The level was easy to medium. The level of questions was easy of those 3 coding questions as well.
Second Aptitude Test (60 minutes):
128 were selected for the second round
It was conducted offline in our college we were given a set of papers containing 12 questions with a total of 33 marks. We were given instructions that we needed to solve each question step by step or at least the approach in the given blank space by which we arrived at the solution. Directly writing the answer would not be considered for evaluation. The test questions were of topics Quant Reasoning and Data interpretation. The level was easy to medium.
Interview Round 1 (~ 40 minutes):
28 were selected for Interview Round 1
It was conducted offline in our college, I was first asked for my resume and a short introduction.
The questions were:
1) Given that an apple weighs 150 grams and a truck full of apples with a standard deviation in weight of 10 grams, what is the probability that the weight of the selected apple will be more than 160 grams?
2) Given a Square of side 10cm and 6 points can be placed anywhere inside the square what is the probability that the distance between 2 points will be more than 8cm.
3) Which are in more quantity the no. of wheels or no. of Doors in Sangli (These types of questions are called guesstimates I would highly recommend researching these questions online and understanding the approach for solving these problems)
4) As I was from CSE, I was told to explain any two concepts of CSE considering the listener is not from a technical background. I explained the concept of finding if a number is a power of 2 or not in constant time, and I explained merge sort step by step.
5) Then he asked me what do you think would a CSE graduate do in our company.
Interview Round 2 (~ 25 minutes):
9-10 were selected for Interview Round 2
It was conducted in online mode. I was first asked to write code for inserting a node with a given value at a given index position into an already present linkedList, I explained each case of inserting a node at head, tail and anywhere in between in detail.
Given that you have 10 lakhs and you can invest in an industry, for the first 2 years they will not be giving you any money but from the third year onwards they will give you 4 lakh each for 3 years so now you have to find out whether it is more profitable than an investment in a bank for the same amount of money and time or not.
At last, I asked what a CSE graduate does in Aspect Ratio
The results were declared and 4 of us were selected.
Deutsche bank visited our college in month of July. They offered a CTC of 19.65 LPA for Graduate Analyst role. The Hiring procedure is similar to many companies. The Deutsche Bank team conducted total of 5 rounds. 1. Aptitude Test(Online Coding test - 90 min) Coding test with 3 coding questions. All three questions were of medium difficulty. First question was on Array Second question was string based. Many student smart played with this question as the output is either yes or NO. So printing YES might clear half of the test cases. Third question was graph(grid) based. 30 students shortlisted and interviews were scheduled after 1 week. 2. Technical Round-1 Round started with introduction followed by discussion on projects that mentioned on resume. This round is time bounded. Interviewer quickly shifted to coding question(n-array tree based). I was able to solve and code the solution completely. Then some questions on CS-fundamentals based on DBMS(ACID properties, Indexing) and OS(Deadlock, Paging). Interviewer also asked a puzzle which I knew as it is one of puzzles from GFG. 3. Technical Round-2 This round started with discussion on project followed by two coding question. One on stack using queue and queue using stack and another on linked list(medium difficulty). Then some discussion on CS-fundamentals(OOPs, DBMS, OS). Asked to write some SQL queries and discussion around it. 4. Pro-fit round and HR round Pro-fit round focused mostly on projects and scenarios based questions. In HR round discussion was related to strength, weekness, goals, higher studies and why DB. Be confident and clear in this rounds. Tips: 1. Go through GFG archives - interview experiences 2. Ask questions whenever given opportunity. 3. Research on company beforehand. 4. Deutsche Bank focus on DBMS and SQL.

Coding/aptitude round:
PATTERN:
1. The 1st coding question was based on strings in which we
were supposed to return no. of unique years from string
consisting of multiple dates(with dates in format dd-mm-
yyyy).
2. The 2nd one was also on strings where the task was to
convert a string like 'a1b2c3' into 'abbccc' which is fairly
easy.
3. In the 3rd question, we were given an array and were asked
to sort it in such a way that odd and even numbers come
alternatively. E.g. if 10 25 20 40 55 is the i/p array then the
o/p array will be 10 25 20 55 40.
CS FUNDAMENTAL QUESTIONS:
1.The core section was divided into 3 parts:
DSA, C++ and Computer Networks.
2. DSA section included questions on stack, linkedlist, queue,
and recursion
3.There was one basic output question, one 2D array ,one
related to exceptions in C++ section.
4. In CN there were questions related to OSI model, parity bit,
port numbers,
Technical round:
Started with my basic introduction. Then he
asked some basic queue questions and real life
applications of queues. Then he moved onto DSA
questions. The 1st question was based on
linkedlist where I had to swap two nodes. As
interview was offline he told me to write the code
on paper. I first explained the approach and then
wrote the code while side by side discussing how
I'm implementing the approach. 2nd question
was on diameter of tree. I tried to explain the
code but wasn't able to properly implement.
After that he asked me about
which data structure and
algorithm to use for storing and
sorting 1 million numbers.
Except one page fault question
no core questions were asked.
HR round:
Similar to TR this one also started with basic
introduction. Then he asked me about my
favourite subject in curriculum and asked
some questions on that. Then there was brief
discussion on my hobbies and interests. He
asked few questions on projects like tools and
technologies used, members in group, what I
did in the project and some others. Also he
asked me what technical things I read apart
from course curriculum like any news related
with startups and others.
After that he asked me why I
want to join Druva which is very
normally asked question. In the
end he gave me some feedbacks
about my performance and that
concluded my HR interview.
TIPS AND TRICKS:
1.Practice coding in different languages(max 2 or 3) before
coding rounds. You never know which libraries might come
handy.
2.Decide to either code first or solve mcq's depending on
marks' distribution.
3.Thouroughly prepare the topics which you can. The
interviewers don't expect us to have answer of each and
every question but do expect us to have proper
understanding of what we've prepared for.
4. Give mock interviews if possible.
5. Briefly greet the interviewers. Do handshake if possibe.
6. Have a smile on your face.
7.Try to maintain eye contact with interviewer.
DO'S AND DONT'S:
Do's:
1.Do proper research about the company, which you're gonna
sit for.
2.Thoroughly check various options and functionalities in
exam portal of the aptitude test.
3. In the interviews have patience and let interviewer ask the
questions.
Dont's
1.Don't be nervous while interviews and maintain your energy
throughout the interview.
2.Try not to interrupt interviewer.
3.Don't talk too much or too less,
nor too fast or too slow and also
not too loud or too quiet.
Deutsche Bank is a Global Investment Bank. The role which they offer is Graduate Analyst with offices at Pune and Bangalore .The CTC offered was 19.6 lpa
Aptitude Round :
There were 3 Coding Questions :
2 Medium level of difficulty
1 Hard level of difficulty
Time provided was 1.5 hrs
Interview Round 1 :
I did see his LinkedIn profile before Interview and got to know he had knowledge and experience of databases so I had cleared that he would take it deep into database.
He started it off with the first question of OS (maybe it was the same question which love babbar has in his OS notes).
Then he asked few more questions on OS (easy to medium level),
I think the OS playlist of Gate Smasher or Love babbar is enough (atleast for this interview)
then he asked about DBMS (ACID , transaction, 2nf
then asked few queries (find highest salary among the table with 3 different methods and nth highest salary, also asked how to join given two tables with some conditions) he also gave me some code snippets and asked me about their output
Asked about OOPs and their importance
then he moved towards DSA.
Started with why do we need DSA?
Then adv of Linked list over Array , then many more questions followed up
He asked how would you reverse a string (approach only )
Asked about searching methods and which is more efficient
Then there was discussion about projects
Interview Round 2 :
In the previous interview I was pretty good at answering questions of os dbms and project but I did fumble at dsa and also didn't answer a few questions thats where they thought that they need to test my dsa
The Interviewer at the start itself said see I'm gonna ask you 15-20 questions and I have list of all these questions, then he read out all those questions,
I had answers for nearly 60% of those and not for remaining ones
So It started and questions were easy to medium level
I was pretty nervous , was fumbling at nearly all questions so I asked for 2 mins of time so I calmed down myself
He was giving me code snippets of data structures and asking me their outputs , in the whole interview he asked about 12-15 code snippets
Then he asked a few difficult questions (I'm unable to remember those)
Then he asked with programming how can u find a file in the computer
This interview was a bit of roller coaster one coz few of questions I was very good and not in a few,
then he asked me a question to give approach using hash maps and I was unable to answer it then I asked him to give me some time to think then I gave him a approach using linked list and I kind of won him with that answer
Then there were few more questions
he asked me to code for few linked list questions
I don't really remember if he asked about project
This was a pretty difficult interview
Interview Round 3 (Professional Fit Round ) :
This Round was non technical
They asked about my family background , my hobbies and achievements
Then asked about my weakness (I said currently I dont have any , I have worked upon my weaknesses ). Then he asked me about finance (as I had mentioned it in the interview)
Then he went on to ask questions about hobbies and strengths
Then he asked about my projects then asked about difficulties which I faced in my project and how did I tackle them
He gave me scenarios and asked how would I behave
He was a pretty chill guy!
You can easily clear this round with good communication and confidence
Interview Round 4 (HR Round) :
General HR questions
Why deutsche bank ? (prepare this answer prior to interview)
asked about my family background
Tips :
See guys you are students you aren't expected to know too much , its fine if you dont know many concepts , all they want is a confident grad willing to learn newer tech
Don't be underconfident or overconfident
the above questions are not all which they asked me, I don't remember all (so don't just prepare only these questions for interview )
Do prepare for HR interview
Do prepare for standard project questions beforehand
I prepared for interviews like I thought that I have to win these interviewer so I did read a book ‘How to win friends and influence people’ before interview and did apply its concepts on interviewer.
This technique came pretty handy in profit round
Always Smile in a interview (smile in the sense that doesn't feel over)
Smile if you answer a question , smile even if you don't answer
Make sure you take control of little things so eventually you turn out result in your favour.
ALL THE BEST !!!!
Veritas was 3rd company visiting campus in the placement year 2022-23. It was a one-day process of all the rounds and interviews. The complete process was an online process that included a Presentation, an online assessment, and all Interviews rounds.
Online Assessment:
A). 20 MCQs baesd on CN, DBMS, OS, and OOPS. All these MCQs were easy.
B). 2 coding questions, one was a variation of string reversal I would rate it to the Leetcode easy category and another one was a DP question, Minimum No. of taps to water the garden it was a Leetcode hard question.
Round 1: (Technical Round || DSA + Project + DBMS + OOPS || 1 hour : 20 Min)
It was a technical round, my interviewer was 11+ years of experience in Veritas. It started with an introduction and asked some counter questions on my project and Hackathons that I won. Later he moved on DSA part, Unlike others my whole interview was DSA-centric. He started with basic questions such as creating a Doubly linked list class and creating some functions to add elements in a Doubly linked list, searching elements in a Doubly link list. First, he asked about the approach and then gave me time to code it up, also asked me to give proper comments and asked what would be edge case and time complexities. Another question was to reverse words in sentences and not complete sentences, I gave him 3 approaches and he was quite happy about my depth in DSA. Later he moved on to Trees and told me to create a Tree class and write code for the Zig Zag traversal of the tree. This was quite an easy question and solved it quickly with proper comments and complexity. After testing my DSA, he moved on to DBMS and asked a few basic questions such as what is Indexing in DBMS? What is the difference between an SQL database and a NoSQL database? What is Clustering in DBMS told me to write a query for Clustering in DBMS. At last of the interview, he asked a few questions on OOPS they were quite basic and easy.
Round 2: (Hiring Manger round || OOPS + CN + DBMS + Managerial questions || 55 Min)
It was the hiring manager round, my interviewer had 16+ years of experience in Veritas. It started with my introduction and then She asked me about my project, hackathons, and coding journey.
Then she asked to tell me the Data structures I know and specify real-life examples of each data structure, I answered it quite well and she was impressed as DS was my strong part during the whole process. Later she asked What are 4 pillars of OOPS are and explain it as if She is a school student and doesn't know anything about coding with some real-life examples. I felt this was the most difficult question in my interview as She was asking a counter question on each sentence I spoke about OOPS. Later she moved on to Puzzle luckily I solved that puzzle as I was knowing the puzzle. It was about a train and a bird. At last, she asked managerial questions and some situational questions, and to every answer I gave she asked a counter question and it was quite exhausting for me.
Round 3: (HR Round || 10 Min)
It was quite an easy round and asked me about me and who took my interviews. Later he asked how many employees work in Veritas, he was just checking If I attended PPT sincerely or not. Then he moved on to discuss the salary structure.
Tips:
1. Prepare DSA properly and in-depth, will help you Off-campus and as well in other companies.
2. Always asked the question to the interviewer if you have any doubts, most of the time they phrase you half question so you should ask about the remaining entities in question.
3. Prepare core subject concepts with some kind of real-life examples, as they don't want textbook definitions.
4. Be confident and tell the interviewer if you don't know the concept or answer just don't give them wrong or made-up answers.
5. Don't cheat during OA, a lot of cheating happened during Veritas OA.
6. There is no special preparation required for Veritas, just focus on DSA and DBMS. No CN was asked to me during the entire interview process but it was asked to another student, So prepare it as well.
7. If you have any doubts or queries, you can reach out to me through LinkedIn.
Thanks,
Shriharsh

Deutsche Bank is a German multinational investment bank and financial services company. Generally, they start oncampus hiring in month of July. They offered the job role of Graduate Analyst. Their process of hiring includes 1 aptitude (coding) test round and 4 interview rounds.
Aptitude Test :
In this round, there were 3 coding questions of medium to hard difficulty. 2 medium and 1 hard question. These questions were based on array, string and graph.
The time given to solve these three coding questions was 1 hour 30 minutes.
4 Interview rounds :
Technical Round 1 :
The very first question interviewer asked was my introduction. Next question was where do you see yourself after 5 years. Then as I mentioned about my internship in resume, he started asking questions about my internship. Then he moved towards technical questions on DSA, OOPs and DBMS.
Questions asked during this interview:
1. Write a code to reverse a string:
input - Hello World
output - World Hello
Interviewer asked me to write this code within 5-6 min. And after 5 min he asked me to stop writing. Fortunately, I was able to complete my code within time.
2. All OOPs concept were asked with real time examples.
3. Deep dive into DBMS.
- Normalise given table till 3rd Normal form.
- How will you achieve consistency in database?
- Deep discussion about locking protocols and ACID Properties.
- How to find nth highest salary?
- Lot of SQL queries were asked to frame on joins, aggregate functions and subqueries. For this, they will give you input tables and also will tell you how the output table look like.
This round lasts about 40 min.
Technical Round 2 :
Second Technical round was a deeper discussion about the projects mentioned in my resume.
I mentioned my top 3 projects in resume. Interviewer asked me to explain any of the two projects. So, I explained 1st project. He asked me the following question regarding the 1st project:
1. My contribution in the project.
2. Tech stack and basic questions on mentioned tech stack.
After these questions, I explained 2nd project which we have built during hackathon in which my team was runner up. I shared my screen and gave live demonstration of that project. The interviewer then asked me about my role in this project. He told me to explain the features of this project. He was quite clear with my project idea and implementation because of live demonstration.
Then after project discussion, he asked me question on sorting techniques and their complexities and to compare them and tell which sorting technique is best. He asked me whether I know about JDBC. As I answered Yes, he asked me a question - how to do database connection in Java (basically, a JDBC connection code)?
This round lasts for 35 min.
Professional Fitment Round :
This round was like managerial round. In this round, they will check your communication skills and will ask about your achievements and hobbies. If you mentioned any club related activity or achievement in your resume, they will also like to know about it. Also, they will give you some scenarios and will ask how will you behave in those situations. They will ask you about your area of interest to work (like which technology you are interested to work in). Also during my interview, interviewer asked me whether I have some finance related knowledge. As I answered Yes, he asked me some financial questions like what I know about mutual funds and investments.
This round lasts about 25 min.
HR Round

Technical Round - 2
HR Round
Are you planning to do MS?
Family background
What does Seimens actually do?
What did you hear about Seimens from your friends?
During the interview, I started with a brief introduction, providing details about my educational background, current position of responsibilities that I currently hold, and a bit about my family background.
Favorite Subject:
One of my favorite subjects is Strength of Materials (SOM).
Mohr circle: I am particularly drawn to the Mohr circle basics and its practical application. The concept of analyzing stress and strain and understanding their diagrams for ductile and brittle materials is fascinating to me. I have also been motivated to explore the various practical applications of this subject.
SFD and BMD Diagrams:
I found the study of Shear Force Diagrams (SFD) and Bending Moment Diagrams (BMD) intriguing, especially when applied to real-life scenarios such as a Cantilever Beam with a moment at the free end. Understanding how these diagrams depict the distribution of forces and moments along a structure provides valuable insights into its structural behavior.
Bending Moment Equation:
One topic I delved into during the interview was the bending moment equation. I shared my understanding of how this equation helps determine the internal bending moments in different sections of a beam under various loading conditions.
Comparison of Strength in Rods:
A question that came up during the interview was about the strength of rods with the same cross-sectional area but differing in their hollow and solid forms. I explained that the hollow rod would be comparatively stronger due to the distribution of material away from the center, providing increased resistance to bending and torsion.
Project-based Questions:
I made sure to prepare my projects thoroughly before the interview. I created a tree diagram outlining the flow of each project, enabling me to present them coherently. I only mentioned the projects that I was well-prepared for and anticipated possible cross-questions regarding them.
Taking Care of Health:
Throughout the interview process, it's crucial to prioritize your health. In my case, my interview was scheduled towards the end, and waiting outside until the afternoon made me feel a bit dazed. Therefore, it is essential to maintain your well-being by staying hydrated, getting adequate rest, and managing stress levels.
Additionally, I had a funny incident during the interview when I accidentally greeted the interviewers with a "Good morning" instead of "Good afternoon." It caught me off guard, but I quickly corrected myself and we shared a light-hearted moment as we laughed about the mix-up. It helped ease the tension and created a friendly atmosphere throughout the interview. It's important to be able to laugh at yourself and embrace such light-hearted moments during high-pressure situations.
Round-1: Aptitude round
It was divided in 4 parts –>
1. Numerical Reasoning – A test that measures your ability to comprehend numerical information presented in tables and charts. It helps us to understand how well you can work with retail-based numerical data.

The day started with a company presentation where they shared what the company does then salary structure etc
Try to focus on presentation as they might ask you questions based on that
Aptitude Round
Then 1St round started it was based on aptitude and coding questions
The aptitude round had almost 15 MCQ questions (CN,C++,DSA 5 each)
MCQ questions were very easy and if you have a good understanding of these subjects then you don't need any extra preparation still if you want you can practice MCQ questions on GFG
Then after that there were 3 coding questions all of them were easy-medium leetcode level questions.
Students who solved more than 2 coding questions(not sure about their selection criteria but try to solve all coding questions) were selected for the 2nd round.
Round I
It started with a general introduction and then the interviewer gave me a Linked list based question and one array based question both were medium level leetcode questions he was more focused on my code quality.
Round II
This was a managerial round where the interviewer was a very senior level druva employee he started with recursion based questions and then he asked about a project that i mentioned on my resume so be prepared and only mention project that you really have good knowledge of
Then he also asked a few behavior type questions like have you ever led any team in any contest or hackathon what challenges you faced(he was concerned about both technical and non technical challenges)
Both of my interviews went in DS and project related questions but many of my friends had questions on OS,DBMS and CN
Talking about any preparation you don't need any special preparation for druva as such just continue with your presentation and focus on CN.

Hi,
About the company-
It's a service based IT company acquired by Deutsche Telekom. In India, the primary development operations are performed at Banglore and Pune offices. The newly opened office at Nagpur handles delivery of cloud and digital services.
Role offered- Undergraduate Trainee
The company has visited campus for the drive on 1st of August 2022, A team headed by then Director of Talent Acquisition, India operaions Mr. Mahesh Gosavi had come to conduct the drive. however the aptitute round was conducted 1-2 days prior to the visit.
The rounds and my experience-
Aptitude round- abt 2 hrs.
MCQs on development (questions on javascript, php, vue js),
verbal ability and English grammer,
simple quantitative (speed, distance, time and statistics),
2 simple coding questions (topics asked - linked lists, stack and queues)
Time is less, preference should be given to coding questions
Discussion round- abt 1 hr. (all candidates together)
(This round was undecided previously and was conducted at runtime, unlikely to happen, can skip this portion, no preparation needed)-
It was quite a unique and intersting round and more of a kind of dicsussion where the team tried to check student's clarity of basic concepts, thought process and corporate readyness. They also answered some of our general queries about transistion from campus to corporate.
A statement was given- “consider cricket ground as an operating system and speak whatever comes to your mind”
We tried to relate the working of operating system with processes in cricket and shared our thoughts. (for eg. synchronization of processes can be related to multiple processes happening on the ground simultaneously. furthermore the state of pitch decides the state of cricket system unlike the state of OS decides the working of computer system)
and some more non technical + technical combo rounds.
Nobody was eliminated in this round.
Technical round- 1 to 1.5 hrs.
Basic DSA quesions (topics asked- array sorting and which technique to be used in given conditinos, string palindromes, linked list, priority queue),
printing star patterns and logic for the same(on paper coding),
project- what, why, how for the techstack used,
I had used firebase for one of my android project, he asked me to convert the non relational schema into relational schema and to design the tables and show interrelations,
he drew a rough design of webpage on paper and asked me what all components and their properties you'll use to achieve this and how would you make it dynamic using backend and database.
HR round- 15-20 mins.
Right after the technical round a short 10 mins of HR round was conducted.
GFG puzzles, some personal questions, view about corporate, which domains you are interestedd in etc.
Some tips-

b) On-campus Hiring:
Atlas Copco conducted a visit to WCE on May 29-30, approximately 1-1.5 months before the commencement of campus placements. The visit began with a company presentation, followed by interactive question-and-answer sessions. The placement process comprised three rounds:
1. Aptitude Test:
The aptitude test consisted of four rounds, each lasting for six minutes. Atlas Copco employed specialized software to conduct this test, ensuring minimal chances of cheating. The primary focus of the test was to evaluate candidates' speed and accuracy. The four rounds encompassed numerical, verbal, puzzle, and gamification challenges. Although the rounds appeared straightforward, they demanded candidates exhibit swift thinking, concentration, and precision during the actual examination.
2. Group Discussion:
After shortlisting candidates from the aptitude test, the next round involved a group discussion (GD). Each group comprised six participants, and they were given a specific topic to discuss for five minutes. The topics varied, covering both technical and non-technical subjects. For instance, my assigned topic was "Is a chat-GPT assistant an assistant or a job replacement?"
3. Combined HR-Tech Interview:
The following day, interviews were conducted, although mine was scheduled quite late. Upon entering the interview room, I greeted the panel consisting of an HR representative and a technical expert. The interview primarily revolved around discussing various aspects of my resume, covering topics such as my introduction, work experience, and family details. Additionally, the panel extensively questioned me on React, APIs, basics of product and system design, deployment, my ongoing research paper, and other related areas. I was also given an opportunity to express my career objectives. Toward the end of the interview, I was offered the chance to ask any questions I had.

All the best!!!
It was First time i think that Media.net came in Over College for Hiring.
As we all know. it is the most Reputed Company such that you can compare its selection process with Google or Microsoft.
Role - ASDE - I (Associate Software Developer Engineer - 1)
Total Rounds - 3 (1 Aptitude Test, 2 Algorithmic rounds and HR call)
it was taken on Interview Bit Platform
and Having 3 Medium - Hard Types of Question.
I able to solve 2 Completely and 1 Partially.
and so i get Shortlisted for next round.
They shortlisted Total 15 Students Only.
In this round The Interviewer gave me only one coding Question
that was given below.
Given num array and index array at every index divide array and collect maximum sum of division in Output array.
Example:
Num = [1, 2, 3, 4, 5, 6]
Index = [2, 4, 3, 5, 1, 0]
Ans: [15, 6, 6, 3, 1, 0]
Explanation:
first Index is 2 so Num array will get divided 1, 2 and 4, 5, 6
so 2 division we have in which 2nd has more max sum i.e 4+5+6=15 so we added 15 in output array.
second index is 4 now array will not going to have 3 divisions i.e "1, 2" , “4” and “6” in which 3rd division have maximum sum i.e 6 so we added into our output array
so on…
This looks simple problem but it is Not.
after applying different techniques I solved the Problem.
He told me to write the code. The code was too complex so i just written half of it and in between i explained him all steps so understood that i can solve the question.
They also asked few Oops Questions and CN Questions and i able to answer correctly.
This round was too difficult for me becase it was totally out off syllabus for me basically.
I never Studied Dynamic Programming that time.
This round was similar like Previous round Just question was Different.
Given different (source, destination) Locations were the Delivery App has to deliver the packages.
with minimum possible distance.
you have given 2 drones to deliver that packages. you can use any drone at any time.
note - starting point of any drone cost zero distance.
Example:
{
[1, 10]
[2, 5]
[6, 3]
[10, 3]
}
24
note- first drone start at 1 and 2nd drone will start at 2.
Hope you Get Everything you were looking at here. still have any doubt then reach me on linkedin i will definitely answer your Query.
Hello everyone,
This article is about the interview experience at Siemens. 🔥
The Siemens was there in our campus in the month of Feb. All were very excited to be the part of such organization which is making a meaningful and positive impact on society.
Whole process was divided in 3 parts:
Round 1: Shortlisting of candidates on the basis of resumes. (As my resume was having basic required tech stand and some personal projects, it was easy to me to get shortlisted.)
Round 2: This round was about conducting the aptitude test😊. The test were consists of nearly about 35 questions.
- 5 questions was based on probability and combinations
- 10 questions was on debugging the code and completing the code snippets
- 15 questions was on basic fundamental concepts of CN and OS
- Remaining questions was based on predicting missing term.
Round 3: It was a interview round. The interview was 40 mins long. They started with Object Oriented Programming Concepts. The first questions was design college with the help of OOPS concepts. Here we had to mention the concepts of clean coding. Like DRY principle, KISS principle, SOLID principle. Means they expect from us knowledge of Low Level Designing.😇 Then they move on to the DSA part. They asked me two questions.
- Reverse a string in pattern of words. (Like make “I Love My India” as “India My Love I”)
- Record Breaking Day. (The day will be record breaking if there will not be any previous day having such a reach.)
The last question was a puzzle. The puzzle was like I have 7 unit of gold bar. I hired one employee. I have to give him 1 unit of bar per day. But I can make only 2 cuts in gold bar.
Overall the experience was good.
Best Luck to all

Hello !!
TRDDC(Tata Research Development & Design Center) came to college around Novemebr - December 2022 . They had a brief presenetation on the company and its research center - the first and most oldest R&D centre in software research in India.
They wanted to take students for internship in Summmer of 2023, for 2 months with stipend . Forms for internship were released specifying the research areas like ML, Cybersecurity. Also they asked for everyone's personal resume, their CGPA……
And after a month, results were out, and I was lucky to get shortlisted for the interview 😁,
around 150 students had applied, and 15 were shortlisted for interview.
Based upon shortlisted students analysis and opinion, shortlisting was done for interview on 2 basis -
1)On basis of CGPA - those who had above 9 probably, were directly shortlisted.
2)On basis of projects mentioned in resume - There were around 70% students who got shortlisted due to their ML, Deep Learning, NLP related project.
For me , I had both the above criteria , so got selected for interview . 😊
Coming to interview, it was a one day event, with interviews being online. on MS-Teams.
Everyone of 15 students had simultaneous interviews due to being in different panels
Some of the questions asked in my interview were -
1)Tell us about your project - I had a Deep Leaerning project in my resume, so I started with explanation, and they went on asking small small details regarding the project since they were totally expert in that field, they knew about each modules.
2)Asked different libraries in DL and their explanation - I had brief idea of project so explained all about the project libraries like scipy, numpy, pandas, scikit-learn …….
3)What was the activation function used by you in the project ? - I talked about PReLU activation function in that case.
4) Are you familiar in ML, where you studied ML from, tell about the different models and their use -I was familiar with DL earlier but was lucky enough to know idea of ML, so was able to tackle the question.
5) What is the data structure /object which is a 2-dimensional labeled data structure with columns of potentially different types ? - I had worked with python, so I knew it was Dataframes from Pandas Library. Explained the details about it.
6) Explain about the objects/data structures like Dataframes in pandas
7) In C++ , do you know what is meant by object oriented ?
8) Explain the pillars of C++ OOPs , and compare it with Python
9) What is Polymorphism and its types , also asked about a virtual function scenario.
10) What all assignments you havedone in C++ ? -For me this was a golden opportunity to impress HRs, I told them that I don't remember a single assignment done by me 😂, but told them that I know what I have learned from those assignments, like I told what happens when I make inheritance with multiple constructors , overloading different operators, working with virtual and friend functions,learned why we cant overload destructors……………………. In short explained all critical things of OOPs in C++.
11)With this interview came to end and they asked about any questions -I had asked like I am currently doing DL project in Healthcare, so in sector is your firm working with ML ? They explained me for 10 minutes, as they thought I had very good interest in company 😉.
And after a week, results were out, and i got selected as summer intern for TRDDC from May-July 2023. 5 students were selected out of 15 shortlisted students(Based on interview, project, CGPA total score).
Tips - 1)Maintain confidence and smile in interview.
2) Don't argue with them over any topic, tell short and crisp answers
3) For me interview was language, object oriented and project based, for some it was DSA.. other domain based, it depends on your interview panel.
4) Answer in smart manner, like the one i did for assignments and always ask doubts about firm at end of the interview, to show your interest.
Thank You !! 😀
