3 rounds. round one - recruiter interview over the phone, asking basic questions about your background. Round 2 and Round 3 are both on-site interviews. being interviewed by overall about 7 peoples including future boss, multiple dept managers, other project managers in the team. each round last over 4 hours. Also, they do not take you out to lunch even though the interview passes lunch time. which is kind of weird. I was starving at the end of interview.
