Initial phone screening took place with the hiring manager. Once through that gate, I was interviewed one on one by three peers of the hiring manager. Two of the interviewers were well prepared and focused on my ability to do the job (based on my experience) and my approach to various elements of the job (budgeting, etc). The third interviewer focused on a job I had several years ago and asked detailed questions about day to day interactions, specific measurements of a particular sub organization under my control, and the level of my technical knowledge regarding the systems I was managing 5 years ago. At Microsoft each interviewer gives a thumbs up thumbs down assessment and one dissenter and undo two positive reviews.

Straightforward, behavioral. Recruiter screen, then hiring manager interview. Final loop round was with 3 other folks plus hiring manager again. Quick process. Received offer within 1 week of the final interview.
