I applied through an employee referral. I interviewed at Amazon (San Francisco, CA) in Jan 2021
Interview
First round with a senior applied scientist, had a very good impression on him since the stuff we did are similar.
Failed at the final Virtual Onsite round, the feedback said that I messed up most of the coding questions.

I applied online. The process took 2 weeks. I interviewed at Amazon (Londres, Inglaterra) in Jun 2026
Interview
After applying online, I received an invitation for an one hour online interview. The interview consisted of questions about my previous work, and then a series of questions on deep learning (specifically on LLMs), and finally a LeetCode style coding question (number of islands in a 2D grid).
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.
