Interview was very technical with five tech rounds and 2 hr rounds afterwards. Interviewers were very professional and knowledgeable. First round was by the hiring manager who explained the job profile very well and asked relevant questions. I did have a round with programming questions - fairly straightforward.

Everything depends on the level of prep. If prep is good then the interviews are easy to crack, if not then it will be the most difficult one. The number of rounds can increase or decrease based on the requirements. On an average 4-6 deep technical discussions is expected
