I applied online. The process took 3 weeks. I interviewed at TikTok in Feb 2024
Interview
30 min of ML basics based on my resume including what is transformer, how attention operates. In the second round, the interviewer asked a more open ended question like how would I go about if the vision-language model ignored the vision modality.
and another 30min for a stardard leetcode
Started with a recruiter screen with simple checks. Then went through 3 rounds of interviews. First 2 rounds were live coding with deep dive on previous projects. 2nd round went really deep of every previous work I did from MLE perspective with being questioned of every possible decision choice. Last was interview with team manager.
