TikTok Site Reliability Engineer interview questions

I had a total of 4 tech rounds and 1 HR interview round. The tech rounds were a mix of algorithms, system design questions, and domain/experience. All the people I met were nice and passionate about their work, the company, and the mission. The recruiter was quick to follow up after the interviews and was friendly and accommodating. Overall, it was a pleasant experience but it was a long interview process.

3 technical interviews and 1 final interview with hiring manager. Technical interviews are more about algorithm problems and knowledge of OS, network concepts and Linux operations. HM will also ask some technical questions as well as behavior questions.
