I interviewed at Microsoft in July 2024. Since I had previously interviewed and performed well, I was able to skip the initial screening.

This time, I went through three interviews:

• Two focused on medium-level LeetCode-style coding problems.
• One started as an object-oriented design discussion but eventually evolved into a more typical system design interview.

I passed this round and advanced to the well-known AA interview. In that round, I was asked more in-depth system design questions. While I held up in most areas, they mentioned that my performance in the deeper aspects of system design was a bit weaker. Ultimately, I didn’t pass that final stage.

Basic LeetCode questions and designing a game.

How would you go about gathering information and writing the relevant classes and database schema?
