I applied online. I interviewed at TikTok (San Jose, CA) in Feb 2026
Interview
The interview went directly to the technical problems, including iOS development, backend, Java, networking, and distributed systems for the first 15 minutes. Then I was asked a LeetCode question about TreeNode and DP. The Interviewer is very nice and patient, give me a lot hint and support.
Phone screen where the recruiter asked questions about my background, why I'm interested in TikTok etc. Also asked a question about a technical project I've worked on in a team.
There was an OA and then 2 rounds of interviews afterwards. 1st round was technical with LC med and basic CS concepts, 2nd round was behavioral questions with hiring manager.
