I had onsite interviews with 6 candidates, each lasting 45 minutes back-to-back.

I had an hour lunch break with a one-year employee who shared her experience working there and showed me the results of her work.

The interviews themselves were all technical, conducted on a whiteboard. They didn't focus much on asking questions about experience or preferences. It was all about demonstrating technical skill and thought process.

The interview questions covered standard CS-related topics such as graphs, algorithms (BFS, DFS, and a traveling salesman variation kind of question), and system design (which is a really open-ended interview).
