It was an interesting experience. The interviewers are quite smart. They will study your resume before coming into the room. I had a total of 5 rounds though I was told 3 - which is supposed to be a good sign but I got a reject and the final interview was really meaningless. My interviewer, the manager, was texting all the time while interviewing me and while I was coding on the whiteboard. That really brought me down and made me nervous which I didn't happen to be all day.
