Microsoft Software Developer Internship interview questions

First, I had 1 Skype interview, afterwards there were 2 technical interviews (sometimes a third interview is added). No HR interview before nor after the tech interviews. The Skype interview was from a central HR division based in Warsaw

Applied online no referral. First round was a phone interview. Was told to expect a mix of technical and behavioral questions. The interviewer was very pleasant and friendly. Was notified of final round invitation a week later. Final round came around and the coldness of the interviewers caught me off guard. The first interviewer was late and did not introduce himself to me. He could not figure out how to share his codility link with me. I had to answer all of his questions verbally without sharing any screen. The second final round interviewer talked about himself and then my resume and questions about myself for the first 80% of what was supposed to be a technical interview. At the end he only allowed me around 5 minutes to work on the technical problem through codility. I verbally solved it and said what I would do if I had more time.
