Microsoft Sr. Software Engineer interview questions

The interview process consisted of 4 rounds. 3 Technical rounds and 1 Behavioral round. The first stage was mostly discussion about what I do and then some relatively easy coding task. Second stage was 2 Technical Interviews back to back same day with 2 engineers. Very smart guys very friendly discussions and no tricky questions. Each interview consisted 3 to 4 tasks. A simple one in the beginning, then they would make it a bit harder, then harder again and then a difficult one. If you are well prepared(Leetcode, Codesignal, Algoexpert, e.t.c) then you have nothing to be afraid of. Overall I was impressed with the experience because it was fast, professional.

The interview process was standard. This requirement was for Azure team The first round consisted of a medium-level LC coding problem and some OS related questions. I was able to solve the problem and run through test cases but took few mins to debug for a particular test case. So the feedback was borderline. The second round had some project-related questions, scenario-based questions, and one medium LC problem. The feedback was good. The third round consisted of a system design problem. Although, I covered the all the points but the interviewer was expecting some more details especially around the services. The feedback was borderline. - The second and third round feedback seemed fair. I still didn't understand why the first round feedback was borderline.
