Phone: 3 rounds On-site: several rounds Culture: profession Problems are neither hard nor tricky. The biggest challenge is Offensive Chinese Interviewer. If they show disregard of your question about the interview problem, don't be frustrated, keep asking what you want to know. If you give up asking, you may lose some important information that you should check with them at first. And when they are picky about your code, or when they indicate that there are bugs in your code, check it carefully, fix as much as you can. And then try to let them discuss the remaining bugs, even if you can't find any more, and no matter how dictatorial they are. Don't end up arguing with them on whether it's really a bug.
