I applied through a recruiter. The process took 2 weeks. I interviewed at TikTok (Sydney) in Apr 2025
Interview
First round technical interview was a medium Leetcode done live. The answer involved turning a nested loop into a looped binary search.
We then moved on to a discussion of solving certain scaling and technical performance problems at the database and web layer.
