Microsoft Software Engineer interview questions

Tiring, but learnt a lot. There were three technicsl rounds followed by an hr . First i gave an OA online. I cleared it snd then continued with iv . Clesred 2 rounds but failed in. 3rd

I had one 30 minues screening interview and in couple of days I got an email with invitation to a full interview day. An interview day is 4 interviews in one day, each 1 hour long, with 30 minutes breaks after each. First part of each interview was about introduction where I was asked to describe some important or critical functionallity I developed for my past project. On first 3 interviews there was not difficult coding challange where I needed to talk to interviewers and clearify details. The last interview was about system design, again, nothing super difficult, I designed an API with user sessions handled by many machines. Pleasant experience overall and all interviewers were quite friendly.
