Went through employee referral. First round is a 1 hour coding exercise, where they send you a set of questions that you have to solve and mail back in an hour. These questions are of moderate difficulty. If you pass this round, they will bring you in for an onsite interview. This interview consists of 2 or 3 rounds of interviews, mostly coding problems. The coding problems are not very tough, and not very tricky. If you can concentrate and know standard algorithms, data structures, programming tricks you should be good. The first interview was great, I really like the interviews. The second round was with a pretty rude Asian guy, who showed such a bad attitude that I just decided then and there that I couldn't possibly work in the same team/office as this guy. He was so impatient and rude, it was unbelievable. Even if a candidate doesn't get what you think might be an easy solution, you have no right to shout, yell or show your frustration on them. Come on man!!! Be professional!! I don't know the answer, fine, just stop the interview or give your feedback to the recruiter. No need to get all American Psycho on the candidates.
