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 !! 😀
