I applied online. I interviewed at TikTok (Mountain View, CA) in Feb 2024
Interview
Start with my resume. Asked a couple of questions regarding my experience. Followed by a Leecode medium coding question. The interviewer asked me a detailed question about what data model I used for my previous ML project. Asked me about basic BL concepts. Followed up with questions I wanted to ask him. After a week I got rejected.
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.
