I had applied online, and immediately received an onsite interview call. Couldn't clear the first round although the questions were pretty easy. The questions were on Tree traversals & binary search. When I asked the interviewer for feedback after getting rejected, he said I did not focus on understanding the questions completely & getting the doubts clarified before I started answering, although I did well in timed environment.

Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
