Interview
The Amazon Science Machine Learning interview evaluates candidates' expertise in machine learning, algorithms, and problem-solving. It includes technical assessments, coding challenges, and discussions on research projects. Emphasis is on both theoretical knowledge and practical application in the context of Amazon's scientific and ML projects.

Applied for Amazon AGI. After first round, it will go into full round of multiple interviews. Lots of modern LLM training technic questions. There are still some behavioral questions, but less than general Amazon roles.
Interviewed with 1 phone screen, 1 coding, 2 ml design and 2 lp rounds. Most questions were non-leetcode questions more related to day to day ml implementations. The questions were very practical.
