TikTok Backend Engineer interview questions

Interview in Mandarin. Full of Bagu silly problems. Experience asked. But bad communication experience. I don't think they understand my expression. They're too focused on what your project achieves in production. Really bad coding question: I've been asking for clarification for 10 mins. The most disgusting problem: the coding problem is to reverse a linked list. The interviewer asked me how many methods I can do this. besides, no input/output format.
