generally well, but the problem is hard, so needs candidate be prepared in both complexity and efficiency. interview is nice to communicate with. algorithm is difficult level, bq is fair level.
Neutral experience
Difficult interview
Application
I applied through other source. I interviewed at TikTok (San Jose, CA) in Dec 2025
Interview
Pre order traversal of tree, need to construct tree from list, no template given, got asked about my resume a lot, dive deep, asked about internship experience and research experience, relevant questions towards research
about my resume, bq questions, some fundamental questions, then a lc,
finally the qa part, but it does not go smoothly. I feel the interviewer did not want to talk to me much
OA, followed by 3 rounds of onsite interview, all three rounds are coding round, 2 medium and 1 hard leetcode level coding, and one of the round asked some full stack related questions
Interview questions [1]
Question 1
