TikTok Machine Learning Engineer interview questions

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.

The first round interview question was more math-focused leetcode and quite difficult. When I saw the problem, I felt a bit lost because I wasn’t familiar with that type of question.
