Microsoft Software Engineer interview questions

1 online assessment with 3 coding questions 3 Tech round 1 hiring manager round OA consisted of String arrays questions, Tech rounds were based on trees, Oops concept and graph

Normal process as you would think, first an interview with HR of around 30 minutes, then a codility OA with 3 exercises which were completed without issues. After this, I was moved to the 3 rounds of interviews and here is where everything went wrong for me. I got super nervous on the interviews and as expected, I was rejected. To be fair, the questions were not that hard now that I think of it, it's just that I was not prepared s I should have been.
