Machine Learning Researcher Interview Experience - London, England
Process
Interviewed at xAI, March 2025. The people were nice, the work interesting, and the problems to work on were nice. I got to the onsite but not beyond. The process was well-organized and quite fast. Expect math and coding questions, and questions about your PhD too.
Questions
Leetcode-style questions and some maths. I don't think it's standardized, and specifics are under NDA.
