There were 4 rounds, 1 leetcode question per round. All the interview was on Lark and went pretty well. If you fail to solve leetcode question, then you probably fail the whole interview.
It's friendly and nothing special interview process. Total around 1 hour, to start with, talking about resume, techniques skills and challenge you encountered. Then some data structure knowledge, and explain OOP. Last give an algorithm question. All the question is not in deep dive, but you have to know everything
