J'ai postulé via la recommandation d'un employé. Le processus a pris 3 semaines. J'ai passé un entretien chez TikTok en avr. 2025
Entretien
3 rounds of technical interviews, each round will have a LeetCode problem. The interviewer also asked about the research projects and some basic knowledge about ML and LLM. Each round will have 45 minutes.
Questions d'entretien [1]
Question 1
one leetcode about sliding window and one leetcode about DFS/BFS on a matrix
Surprisingly straightforward — I expected a tougher challenge for a machine learning role. After a quick recruiter screen, the first technical round focused on implementing K-means clustering, which felt familiar. Handling edge cases for empty clusters was tricky, though. What really helped me prep were the algorithm explanations on PracHub, which gave me confidence going in. The final interviews were a mix of problem-solving and behavioral questions, and in the end, I received an offer that I accepted. Overall, it was a decent experience.

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.
