Microsoft Internship, Software Developer interview questions

I had one codility with 3 question - I was 6 month ago and more practice (style leetcode) is needed. First question was easy, second and third med - med high.

There are several interviews but you need to pass each one to go to the next one. The first interview is about your background in software engineering. I didnt pass this first interview. They asked a few questions about why microsoft, what I did in college, preferred languages and several questions like this. They also asked me a puzzle question and 3 code questions to do in an hour outside of the interview.
