Microsoft

I applied through a staffing agency. There were two interviews. - The first one was focused on system design. - The second one was a review of my entire career, with a discussion of the biggest challenges and a lot of technical details.

The interview process included a phone screen, three virtual onsite interviews, and a recruiter screen. All interviews were one hour long. The questions were from LeetCode Microsoft-tagged questions.

Questions on graphs and other topics were covered over four rounds. It was not that hard, but DSA practice is needed to clear it. The design round was mostly based on my experience, so if you have done design work, you can do it easily.
