I applied through a recruiter. I interviewed at TikTok
Interview
I got the interview invite from a recruiter where I got the contact from linkedin. I had a screening interview with an interviewer for 1 hour:
1. Coding interview which cannot be seen in leetcode.
2. ML knowledge on recent topics.
3. Questions to interviewer.
Interview questions [2]
Question 1
The coding problem was 403. Frog Jump Leetcode problem.
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.

Question 1
implementing K-means clustering from scratch and handling empty cluster edge cases
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.
