Other information about Brother Wheel.

There are five rounds of interviews from interns to full-time employees. What impressed me the most was that the interviewer asked me a lot of complicated questions in one round. Finally, they gave me a question about updating the binary tree of clues online. I can't remember the specific content.

I only remember that it took me a long time to finally come up with a correct algorithm. Time has passed and I have no time to write code on the whiteboard. Later, I finally passed the interview, and I finally got into one of the few places. But I heard that the restrictions began to relax after a few months, and it was not as difficult as when I interviewed.
