Microsoft SWE Intern interview questions

There were 2 rounds (3 for some). I was asked questions based on trees and binary search. LC mediums. No questions from OOP/DBMS, although I was asked about OS because I mentioned liking that subject. The interviewer was very senior (an Engineering Manager with decades of experience), but was surprisingly patient and friendly.

the interview was online. final round was two 45 min interview. Both asked about my previous internship experience, and some of my previous school projects, then one coding question, then let me ask questions.
