I applied online. The process took 4 weeks. I interviewed at TikTok (San Diego, CA) in Nov 2025
Interview
First had a leetcode OA mostly medium/hard level questions then two more rounds seemed like the standard interview process for a big tech internship. They did not care about what year I was in university seems like they hire highschool kids even.
Interview questions [1]
Question 1
They asked me a 2d matrix question about 0s and 1s and transforming them
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.
TikTok’s interview process usually starts with an application and recruiter screen, followed by an assessment or technical test, several interviews with team members and hiring managers, and a final decision or offer. The exact number of rounds depends on the role, location, and whether it is technical or non-technical.
