ByteDance interview questions

For me there were 3 rounds total; but sometimes they do 4. First round was my direct leader; second round manager; third round HR. I interviewed at Bytedance in Feb 2021.

I had three technical interviews and one interview with a hiring recruiter. The interviews are about coding, projects on the resume, and other related machine learning and Python skills. Each interview is at least 45 mins and at most 70min.
