Multiple rounds of interviews, 1-2 hours each. System design, coding challenges, behavioral questions. There were a couple times during the interview that the interviewer didn't quite know what to do. After many hours of questioning getting asked about tennis balls was out of left field. The system design interview was interesting but not a real world problem and the interview kept making up more constraints.

Simple behavioural and Java-related question that could be considered a Leetcode Medium. The interview process was smooth; they also asked about me personally, and we spoke about our interests. The coding question took no longer than 8 minutes to go through.
