I applied through a recruiter. The process took 3 weeks. I interviewed at TikTok in Aug 2025
Interview
I first had an HR phone screen, followed by two technical coding interviews over the next two weeks. I was rejected at this stage, but usually there is an additional Hiring Manager interview afterward.
Interview questions [1]
Question 1
One round was a string simulation problem, and the other round involved data structures, specifically a heap and a binary search.
Normal interview, nothing special. First introduce yourself, then doing interview, then ask questions. They asked me a hard leetcode question and a medium question. I did them but failed the interview
