I have 6 rounds total, including 2 coding, 2 semi-behavioral, and design rounds.

After one of the algorithm interviews, an interviewer quickly buzzed me with a few behavioral questions.

The coding questions were medium-hard level problems. They covered sliding windows, sorting, hash maps, and breadth-first/depth-first search.

There wasn't a "classic" system design round with diagrams and such. Instead, the engineer asked how I would handle high load under certain restrictions.
