ByteDance Backend Developer interview questions

ByteDance gave feedback very quickly, right after the interview. The process was fast. Interviewers are nice and supportive. 1 hour for each interview. I finished 3 interviews in 2 weeks.

First round interview. Online. The interviewer was nice. Questions were not hard but needed a solid understanding of Java. Lasted for around 1 hour. First half was conversational, the second half were coding problems. The interviewer gave hint during the implementation. Also needed to speak out how the code was structured.
