They claimed the remote interviews would have at most 3 stages, but I only went through 2 that day. Self-introduction and a few basic questions about OS, OOP, and C++ at the beginning of each stage. The remaining is a typical coding test where the questions are often seen in Leetcode.

3 stages The first round is conducted w/ an RD. He asked me about the CV for ~20 mins, followed by few classic OS questions. 1 medium LC questions at the end. The second round is mainly HR asking BQs. The last interviewer is the manager on the team. We spent few minutes on my experience, and done a LC medium problem.
