I applied online. The process took two months.
The process consisted of three onsite interviews:
The questions were well-balanced between real-world problem-solving and algorithmic thinking. There were no trick questions or puzzles. The interviewers were experienced engineers who cared about how you think, not just whether you get the right answer.
Finally, there was an AA (As Appropriate) interview with the HM. They went over my CV and asked both behavioral and technical questions. We then moved to a system design problem and wrapped it up with questions regarding the team, etc.
LeetCode style questions (medium) and more.
The following metrics were computed from 287 interview experiences for the Microsoft Senior Software Engineer role.
Microsoft's interview process for their Senior Software Engineer roles is very selective, failing most engineers who go through it.
Candidates reported having very good feelings for Microsoft's Senior Software Engineer interview process.
