Microsoft Intern interview questions

Behavior phone screen. Simple 30 minute conversation regarding past projects and why I am pursuing software engineering. Was also asked about why I wanted to work at Microsoft and my favorite Microsoft product. The interview wasn't very technical was the exception of a few questions related to CS fundamentals.

I was flown out to their headquarters in Warsaw, Poland. They paid for all travel expenses, accommodation (2 nights in a 4-star hotel) and food. The interview consisted of 5 rounds, each taking 45 minutes. Every interviewer covered a different topic. All questions could be found on leetcode type of websites, other than a single question that was system design. Overall, I did not prepare well enough, but after a couple of days of leetcode, and covering some design principles and I don't think anyone coming from a University should have a problem. You can use any language you want, and the programming is on a whiteboard.
