Machine Learning Engineer Interview Experience

August 8, 2026

Negative ExperienceNo Offer

Process

I applied through a recruiter, and the process took two months. There were five rounds in total, all structured the same way: a technical Q&A segment followed by a coding exercise. The coding questions sat around LeetCode medium difficulty, and the remainder focused on drilling into specific projects from my resume. The difficulty was manageable overall, and it is worth noting that parts of the interview were conducted in Chinese.

TikTok Work Experiences

Bad leadership and junior management

Machine Learning Engineer • Current Employee

Singapore, Singapore

Pros: * Name of the company * Compensation is not bad when you join

Cons: Leaders have no vision for this company. Endless hire, fire, reorg, delivering absolutely nothing. Worst infrastructure I have ever seen; very unstable. Junior management. Most mid-level leaders have no idea how a normal company looks. Environment is becoming toxic. Sometimes other departments stab you in the back, and everyone feels insecure. RSUs have limited buyback, which makes the total compensation not as high as it looks. If you don't speak Chinese, you are definitely marginalized.
