I applied online. I interviewed at TikTok (San Jose, CA) in Jan 2026
Interview
the interviewer can't figure out whether my solution is correct or not, giving very unclear feedback and was really rude through the entire interview. I think he was doing something else while interviewing me, when I had questions, he always take around one minute to give a proper respond, which I assume he was using AI helping himself to come up with an answer.
Interview questions [1]
Question 1
the question is to implement a function that figures out whether a tic tac toe game is over or not. Don't care about what input the function takes in, and there are no other rules other than what is defined as a game over.
