Detailed experience
I was initially asked some questions around my projects, some CS Fundamentals like, Polymorphism and all. All of them can be found in top 100 gfg problems, that much is sufficient. Then he took me to hackerrank, and pasted a dsa problem. Later I found out it was LC 983. I had not seen this problem earlier, thinking about two minutes, I made complete solution map in my mind, how to tell and all. I started by explaining my approach, and the intended time complexity for the recursion solution to it. Later explaining its exponential time complexity, then he asked me to move to the better solution, so then I explained how we can use memorization method in the problem. I wrote it and passed all the test cases in one go. Then he wanted me to write tabulated form, and asked just to tell approach or a rough code for tabulation. I wrote code for tabulation within 3-4 minutes, as fast as possible along with explaining all of my approach, quickly, as he wanted me to be quick. I wrote it and he did not want me to run it. And at the end told me to ask anything, So I asked about any current technologies as a fresher we must focus highly on. The interview ran for about 1.25 hours initial 30 minutes for projects and core CS, rest time for all the 2-3 approaches for a single problem. This was average time for all the interviews. Initially I thought I took much time, but later came to know they were taking this much time only for interviews. I got rejected might be because of my bad luck. It was one of those I was highlyy aspiring for, but could not even make it after even passing all test cases, properly. Better Luck next time !!!!
