J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez TikTok en avr. 2024
Entretien
I had two rounds of interview. Both followed the same format. Comprised two parts - an interview and a coding question of 30 minutes each. For my first round was asked a Leetcode hard about Streaming Median Finding - LC295 and the questions about my resume and how Diffusion Models work.
The second interview was a similar format. Although the questions were about ML System Design - the interviewer could not speak English and had connection issues, so he kept disconnecting every one minute. Which was not the best interview experience. He dismissed all my answers very curtly.

Entretien
The interview process consisted of multiple rounds including an online assessment, technical phone screens, and virtual onsite interviews. The questions focused on machine learning fundamentals, coding challenges, and system design. The recruiters were responsive and kept me updated throughout the entire process.
Asked heavily about my resume, mainly focused on the projects I did that had overlapped areas with the team. Did an easy coding question on calculating a ML metric and asked about how to optimize the solution.
