Microsoft Software Engineer - Internship interview questions

I had a first round interview at my college campus. Within a week I was contacted to set up a final round interview at Microsoft. The first round was a 1 hour interview, the final round was 5 separate 1 hour interviews. All asking technical questions

Got selected for an interview at a career event. Interview was scheduled two weeks after my first interaction with the company. It was a half an hour question which involved one coding question.
