They have a total of 3 rounds.

The interviewer in the first round was sensible and asked questions related to the position.

However, the interviewer in the second round could hardly speak any English. He kept asking technical questions (completely unrelated to the position I applied for) for 1 hour and 20 minutes, and later presented a LeetCode hard question. He didn't even allow 5 minutes to solve the problem, stating it was beyond the 1-hour interview time, and then ended the interview.
