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.
