The interview process involved two rounds of interviews on campus at my school, followed by on-site interviews. The on-site interviews were conducted in a large group of students, featuring two interviews back-to-back, followed by lunch. Everyone received decisions after lunch.

Overall, the experience was pretty smooth. I heard back quickly after each round of interviews, and Microsoft paid for all expenses during travel for the on-site round. It was definitely one of the smoother experiences I've had.

The only downside is that interviewers don't have access to any feedback when delivering your result. This means they can't even tell you how long until you can reapply, as it depends on how close you were to being hired or not. Consequently, you'll have to email your recruiter separately and hope for a response.

Almost entirely data structures and algorithms questions.

Nothing overly atypical. Surprisingly, I didn't even get the "why do you want to work at Microsoft?" question that I've heard is really common.

Almost every interviewer asked a generic "What's a difficult problem you've worked on?"
