Its mainly an extension of HR round but you should be ready to face some weird apti questions and puzzles. I was asked a very interesting question which fortunately I was able to solve (do not remember the details now, but remember using calculus for that puzzle :-|). Rest of the interaction is about the job role and your fit. Keep asking smart and engaging questions. The interviewer will be the head of the office who is a partner. So, this round counts a lot. Anyways your chances are good if you have reached this round because generally it is the last round. Yes, FYI, all rounds are elimination rounds
