Normal process. But strange thing that during system design they asked tough theoretical question, but during next interview about ml they asked about difference between classification and regression. And I didn't find that interviewer (during classic ml interview) was interested in that process. Don't like it.

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.
