Microsoft

First round: Contacted by a recruiter. Had a coding question to solve in 45 minutes, along with an explanation. First, introduce yourself, then start with your experience and projects, and finally, the coding question.

I had 4 rounds of interviews. All 4 rounds had the same structure: A 1-hour interview comprised 30 minutes of questions and 30 minutes for coding. The interview questions covered computer science fundamentals, system design, and past projects.

The interview process was pretty smooth, and HR was very responsive. There were four rounds of 1:1s with breaks in between. I spoke directly to the hiring team and manager and learned about their work style.
