I talked to a recruiter who set me up for an in-person one on one interview when Micrsoft recruited on campus. It took about 45 minutes and was mostly chat, except for one programming question. I was told to expect email from a recruiter within 3 weeks, and sure enough, within three weekes I was contacted by a scheduler for an onsite interview. A day or two before the onsite, I was told which team I would be interviewing with. (I'm still rather unsatisfied with this part because I felt that I had no choice in the matter.) The onsite started out with a briefing with yet another recruiter who told me what to expect. Then I went into 4 successive interviews, each with a technical and a people skills portion. At the end of the day I met with the recruiter again to debrief. At that point, I knew better than to expect an offer because I knew I'd messed up several times early on in the interviews.
