I was contacted by the recruiter a day after submitting my application online.

The first round was a 30-minute on-campus interview. It mostly consisted of behavioral questions and one technical question, something along the lines of reversing every word in a string. The interviewer was friendly.

I was selected for the second round of interviews at Redmond. There were four back-to-back interviews.

The first was an easy programming question about vectors/arrays. However, it had many edge cases to cover, and the interviewer expected me to ask a lot of questions.

The second interview involved thinking about how the touchButton function works internally in iOS app development and reading some C# code (I was allowed to ask questions about the syntax).

The third round had a design question. The first three rounds were not that difficult.

The fourth interview was completely random. It involved OS and ML concepts – classes that I have not taken yet. The interviewer did not seem to have an idea about my skills and resume.
