TikTok's For You Page is one of the most sophisticated recommendation systems. Study collaborative filtering, content based recommendations, user engagement metrics, and real time personalization.

TikTok interviews include a mix of behavioral questions (using the STAR method), technical or domain specific questions, and situational problem solving. The exact mix depends on the department and seniority level of the role.
