Microsoft Program Manager interview questions

Online application, Hiring manager viewed my Linkedin Profile, and then contacted me directly for a MS team interview (45 Min) Coming from a software engineering background I was expecting a more personalized interview based on the experience. It felt like a hasty process or like the decision was already made and the conversation was only formality. The interviewer were not genuinely interested to hear and also analyze my answers. He even mentioned a few times that we can't spend much time on this part of the interview, need to move on, etc. I was asked about a system design if a company should do and how and a couple of standard behavioral questions. I did not even get the chance to ask all my job related questions due to the time constraint. To me it looked like I did good enough but I got the rejection letter a day after.

My first rounds was a phone interview scheduled to be for 30 minutes but it lasted 22 minutes. The second round was a series of 4 interviews in 1 day. First one was very hands-on: the interviewer picked up a random topic from or ongoing conversation and didn’t provide me with much details. Other 3 went well - they were about product design and the last one was more technical but a design question none the less.
