The process took 3 weeks. I interviewed at TikTok in Mar 2023
Interview
I took the technical assessment, was extremely difficult. Lack of responsiveness from the hiring team. Questions are all 3 stars difficulty on hackerrank. I would advise revising all data algorithm and structures concepts before attempting the test
3x leetcode medium with some behavioral mixed in. Hiring manager round asked a bunch of behavioral stuff and gave 15min at the end to do leetcode mediu. All leetcode asked were on the harder side of medium.
The interview process consisted of an initial HR screening followed by a technical interview with the engineering team. The technical round focused on backend fundamentals, including data structures, system design basics, and problem-solving questions. There was also discussion about past projects and experience. The interviewer was very nice, professional, and made the conversation comfortable and engaging. Overall, the process was smooth and well-structured.
I applied through a recruiter. I interviewed at TikTok in Nov 2025
Interview
3 technical rounds. started off with HR call then first interview was a resume deep dive and med LC question, second was a hard LC question, third was a systems design question. finally, a HR call to negotiate.
