Citadel

I applied through a staffing agency. I was asked to apply through a third-party recruiter. Got an online assessment test a few days later. It was standard LeetCode problems that were not too difficult to solve.

OA, technical screen, 3 more technical screens, and then team matching. Most of the questions were medium/hard LeetCode with some low-level systems questions too. Overall, the communication from the HR team was fast and good.

I was asked to build a linked list in Java and answer other standard LeetCode questions. The questions were not too difficult, and I was also asked about generics. The interviewer was not too friendly and seemed to be doing other things.
