I applied through a recruiter. The process took 1 week. I interviewed at TikTok (London, England) in Apr 2021
Interview
Got contacted by a recruiter on LinkedIn and set up the first technical interview. I wasn't expecting for this role the interview to be complex (FAANG style) considering that the role is 50% coding 50% business. Although the interviewer was super nice and supportive.

Question 1
Complex question related to backtracking, if you haven't studied this stuff before no way you'll come up with a solution within 45mins
Quick phone interview
2 leetcode interviews
Cross functional interview
Interview with manager
Overall, a hard process. Aligned with other big techs. If you study for leetcode, you should be fine

I applied through a recruiter. I interviewed at TikTok in May 2026
Interview
60 minutes virtual interview. Started with a brief introduction, a few questions about resume, then the leetcode style coding interview. Got 2 medium questions. The interviewer would ask about the complexity and the potential optimization.
First meeting was a quick HR discussion. 30minutes. We talked about how I would fit into the role and what is the team composition. The next one was a live coding task relate to algorithms like what you would find from leet code.
