- Resume (via refferal) - OA (3 weeks upon resume submission). 2 med lc, 1 hard lc. - Got an email from HR, told me that there would be 4 more technical rounds. - First 1:1 technical round: 10-12 questions about recent experience, fundamental internet network knowledge, SQL. 1 easy-med coding question. - Second 1:1 technical round: Similarly, this time the interviewer focused on my knowledge and concepts written in my cv: OS, message broker, elastic search. 2 easy-med coding questions. (1 week from 1st round) Got a rejection mail. Perhaps, the coding round was not smooth, I took a moment to realize where I was wrong, also I was not too good at message broker. If I knew some Mandarin, it could be a huge advantages.

Went through two out of three interviews with TikTok, in both they asked basic concurrency, networking and language specific questions as I was going for a C++ role. They also asked Leetcode Medium questions in both interviews.
