Microsoft Explorer Intern interview questions

Process began with a friendly phone interview with a recruiter (non-technical and mostly program-management related). Series of 3 on-site interviews, including one with a dev manager that mixed technical and product design questions. Technical and coding questions were fairly straightforward data structures & algorithms questions. Interviewers were very friendly and generally enthusiastic when answering questions about the company.

Was called about a month after submitting my resume at my school's career fair. Had a non-technical phone screen asking me about a couple of my projects and found out after a couple of days that I would be flown out to the headquarters in Seattle. I had three interviewers, one by a senior PM and the other two by software engineers. The PM interview asked me some broad design questions and the other two delved into sketching user interfaces and coding on a whiteboard.
