Two basic LeetCode problems with difficulties of medium and hard, and C++ basic knowledge with a bunch of follow-ups. The whole interview is intense but worth a trial. The interviewee is kind, and the whole process lasts 1 hour.

Two rounds with a software engineer from the team. LeetCode questions around medium difficulty. Asked about background as well as gave context of the job. Smooth process with a quick turnaround; HR was responsive.

First, you apply and get an OA. If you score well enough (you don't need a perfect score), then you get the interview, where they give you really hard questions. It depends on the interviewer, but someone I knew got an easy string question.
