Extremely unprofessional company. My profile got passed around several teams and I interviewed probably 8-10 times in total.
All interviews are conducted in Chinese so beware!!
After passing the technical interviews and HR round, I was told there’s a hiring freeze and asked me to interview with another team. I suspect they are just interviewing locals to meet the govt quota to hire their own people
Interview questions [1]
Question 1
Write code for:
1. Composite probability function
2. Find cube root solution
3. Implement a queue via 2 stacks
4. Code out the self attention module
5. Write out the binary tree class
three rounds, each has coding + ml basic + resume related questions
understand all the details in resume is important, since might go very deep down the project you have worked on
The first round was mainly a CV walkthrough.
The second round focused in depth on one specific project.
Both rounds also included LeetCode medium-level problems.
The third round was with the hiring manager with both project and problems for their business.
I applied through a recruiter. The process took 1 week. I interviewed at TikTok (San Jose, CA) in Mar 2026
Interview
