Microsoft recruits at my college. I applied by talking to the recruiters at the career fairs. The first round of interview was on campus. Standard 45-minute interview. The first half of the interview was behavioral, we chatted about my resume and experience and what I like to work on. The second half was technical, and the question was not difficult at all. I heard back 2 weeks later and scheduled my on-site interview at Redmond, WA. I had four back-to-back interviews. The interviews were mostly technical on standard algorithms and data structures, but they weren't hard either. Final thoughts: compared to Google and Facebook, Microsoft's interviews were much easier. They really want to see how you think, rather than grilling you with DP questions.
