I applied online. The process took 4 weeks. I interviewed at TikTok (London, England) in Mar 2022
Interview
Went through 4 rounds of interviews, the system designs questions went very well however I did get tripped up on a leet code style coding question. I made it to the final round but unfortunately did not get the job. The last round was a very awkward and intimidating interview with someone from china who gave me another coding question to answer. I found this part very awkward and cold.

I applied through an employee referral. The process took 2 weeks. I interviewed at TikTok (San Jose, CA)
Interview
3 rounds in total. Every round will have deep dive on Resume, foundation questions, 2-3 Coding questions, BQ questions... Overall fair enough. Coding on their own platform. Might interview in Chinese sometimes.
First round of tech interview: 3 questions, 1 SQL hard, 1 SQL medium and 1 brain teaser. Interviewer asked to code in a notepad and insist my solution was wrong. As I couldn't run the code in IDE I couldn't prove my code was right. After my interview I ran my code and it is working perfectly well.
