Microsoft Intern interview questions

30 minutes interview on school campus with just one coding question. Talked about some features specific to interviewers team and some of my past projects. Informed of advancing to final round 2 weeks later. Didn't here back for 3 weeks after that, so I emailed recruiter and was told there was a backlog of applicants, switched to SDET to accelerate the process. Had interview in Redmond 3 weeks after that (8 weeks since first interview). Final round was 4 45 minute interviews.

Multiple rounds spanning over few months. Shortlisting after each round. First round had about 15-20 objective questions to test really basic skills in 1 hour. Second round consists of coding on 2-3 given problems in 1 hour. Next up is phone interview in which they might ask puzzles or other computer science questions. Finally 2 face-to-face interviews with increasing level of difficulty and shortlisting too. Interviews consist of both questions testing your skill and also related to your background and resume.
