1: online coding round
2nd round was technical round taken by a fresher guy.
He asked my strongest fields , I said DS Algo.
Then he asked me two check if a linkedlist is palindrome or not. I gave him O(n) approach but he did not ask me to write code.
Then he asked me a to find n+m-1 pairs from two unsorted arrays of length n and m.
I gave him O(n*n) approach but he asked me to optimise it although it could not be further optimised.
Then he asked me 2 puzzles which I could not answer.
Then he asked me longest palimdromic subsequence.
I gave him approach to solve using lcs.
But he said to optimise it in constant space Although it was not possible but he said it can be done.
Then he moved to Java Although I said I am not that good in Java.
I felt positive regarding my interview, Still got rejected.

    First round was a F2F discussion at the Noida office. DS questions along with Java concepts were asked. The second round was mix of design questions and DS round. The second interviewer seemed he had never taken an interview before. He was not clear what he wanted to ask in design question round. He came without pen and paper and asked me to code/design on table instead!! He was taking calls in between the interview and also was expressing himself in words like 'It's not fun".He seemed very crude. Companies should train such people in interview taking etiquettes. He kept on saying he has less time and if i can speed up. Worst Interview Experience ever !!!!!

    1st round was coding test on Mettl with 1 hour time limit. It had 2 questions. I cleared the first round and waited for 2 hours for the second round during which they served the candidates snacks and coffee which was a great gesture. Round 2 was F2F in which I was asked about my project and a few DS/Algo questions. I couldn't answer all of them. The HR let me know that my feedback wasn't positive and I was done.
