In my experience, Microsoft interviews tend to build off of each other. You start off with a fairly simple interview, and the things you mess up (or that the interviewer didn't feel you were especially strong on) are the things they probe deeper on further into the interview. I'm not at all surprised that you felt it was pretty easy if you only met with 3 interviewers, considering a full loop is ~6 real interviews with a fluff interview at the end if you've 'passed'.
