It is a 1-hour interview with the interviewer, including the LLM foundation knowledge and two LeetCode questions. The questions include the attention mechanism and the GPU architecture. Deep dive into the resume, about how to design a multi-agent system.
It began with self-introduction and past projects. Then the interviewer asked a few questions about the project. Then ML coding test. For me it was CLIP at first. I wasn't able to do this, so the interviewer changed it to a naive CNN.
I applied online. I interviewed at TikTok (San Jose, CA) in Jan 2026
