Bhagwan Parshuram Institute of Technology, Delhi Placement Interview Questions

Round duration - 145 Minutes
Round difficulty - Easy

the online round was conducted around 5 pm. Round 1 was the initial online round. It was made up of 4 sections - a code debugging section (20 minutes), a coding test (70 minutes), a workstyles assessment (20 minutes) and a reasoning ability section (35 minutes). For me the level of this online test was way below standard. Code debugging and aptitude part were very very easy. The coding questions that I got were also easy but there were a couple of good questions that other students got. But overall, the level was easy. I think the selection was made totally based on the workstyle assessment. Amazon focuses largely on its 14 leadership principles. Make sure to incorporate these principles in your answers. Again, do not start lying blatantly. Make smart and well thought out lies.

This was the first technical interview. This is where it started to feel like Amazon. At first the interviewer gave his introduction, then I introduced myself and afterwards we moved to the coding part. He gave me three questions out of which I coded the solution for two and gave the approach for the third one. He was so helpful throughout the entire interview. I was stuck at the first questions and speaking out loud helped me there as he instantly realized what mistake I was making and quickly pointed it out. Out of all the interviews it was my best experience so far. For technical interviews at amazon you will have to prepare everything as they asked questions on almost all data structures. So, I would suggest you to do as much questions on leetcode as possible. Medium level questions would be enough according to me no need to do a lot of high-level questions. But if you are associated with pep coding then just do the class questions sincerely and you are good to go. Also, one thing I would like to add is to make sure that the variable names that you use are meaningful. Both my interviewers were very satisfied with my code and one of them even thanked me for writing clean code.

This was the second technical round. In this round the emphasis was on time and space complexities. Luckily, I again got a very friendly interviewer who helped me a lot during the interview. The interview started with the introductions then we discussed about one of my projects. I was given only one question to solve which I did with the help of interviewer. There is not much difference between the technical round except the slightly greater emphasis on complexities in the second round.
