I applied through a recruiter. I interviewed at TikTok
Interview
The interview process consisted of multiple technical rounds, each heavily focused on data structures and algorithms. The questions were standard LeetCode-style problems, very similar to those frequently tagged for the company online, and required you to code an optimal solution live with the interviewer.
