3 rounds. 2 telephonic The interviewer asked few apti questions but were unsure of answers. Even giving wrong answer i was selected for next round. 1 f2f it was funny to see the interviewer as he was asking questions and then giving sarcastic smile and then proceeds with his own professional stories. The interviewer acted as if he was strict but his words n body spoke other way. They focus on apti and problem solving skills during interview but that is not at all required in job.
