Microsoft Software Engineer - Internship interview questions

You first have to pass a written test (2 or 3 hrs, 4 tasks - algorithmic). Then 4 hour interview with 4 different people. Every interviewer gives you one question to discuss.

One slightly confusing interview on campus followed by on-site interviews that tended to be easy coding questions or more general thought experiments. A little math, a little coding, and a little general design knowledge were expected.
