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.

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.

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…………………….
