many technical questions in the final round, machine learning, file system design, automation, process methodology, robotics algorithm, dynamic programming, sorting and so on. tons of questions about other area as well, for example, professional communication between coworkers, conflict resolution, productivity improvement idea, project management and so on. pretty fun to interview with those guys, and you can immediately tell they are all super smart.

it was ok. I actually missed many questions. Didn't really get everything answered perfectly.
