5 interviews. 3 technical and 2 behavioral/management (as I got one was extra).

Technical interviews were pretty interesting, not the usual LeetCoding, but more practical.

Behavioral interviews were with Russian guys (I'm Ukrainian).

Interview #1 was about MultiMap (a dictionary that can map multiple values per key). Check IEnumerable (implementation).

Extension methods like Union, Intersect.

Interview #2 was about concurrency. Check async/await and methods of synchronization like Semaphores/locks.

Interview #3 was about system design. Create a design of Google Drive -> Edit text file in cooperative mode (parallel editing by multiple users).

Interview 4 was named "Team Matching." Behavioral questions, experience, etc.

Interview 5 was an extra interview. They gathered 4+ interviewers and asked everything, from technical questions to behavioral ones. The strangest interview with a pretty unfriendly attitude from the interviewers.
