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.
