Pretty good experience. Five minutes to introduce yourself. The interviewer is friendly and likely to help you out if you are stuck in some minor problems. 5 minutes to ask any questions.
Surprisingly, the interview has nothing to do with frontend, and not even javascript. Just normal leetcode style interview, and I did with Python. They will ask you on follow ups, time complexity as usual.
I applied online. I interviewed at TikTok (San Francisco, CA) in Nov 2020
Interview
I applied online. The interview starts with a call from HR, the next three interviews are all technical. I would recommend studying leetcode hard questions and learning more about TikTok's work culture.
