I applied online. The process took 3 weeks. I interviewed at ByteDance (Shanghai, Shanghai) in Apr 2022
Interview
3 Rounds, 2 with engineers on the team(1 hour each) and 1 with PM(40 minutes). Everything is what you'd expect, questions usually derive from your cv and they can range from computer networking to distributed system. There are coding questions but they are very standard. Out of 3 interviews I was stuck on 1 of them slightly, but I finished the solution after the interviewer giving out hints.

Question 1
Coding questions include: Flip a binary tree, level order traversal, and one other 2-D DP question Other questions include: how raft works, how TCP works, TCP connection establishment/teardown, how TCP ensures reliable data transmission, difference between processes and threads, tell me something about epoll, have you heard of io_uring, DB isolation levels. If you have read relevant books such as CSAPP then you should be able to answer all of them
