I applied online. The process took 2 days. I interviewed at TikTok (Bellevue, WA) in Jun 2025
Interview
2 coding + 1 bg + 1 bg from another team.
Coding is regular LC question. BG is kind of random chatting, guess it was why I failed. The last 1 extra BG, they said I seems to be more fit to another team, thus one more round. but failed anyway.
