I applied online. I interviewed at Amazon in Apr 2023
Interview
One code question and several follow-up questions. The code is more ML-based instead of Leetcode type. Follow-up questions focus on understanding and implementation efficiency (computational time and memory, what if...).
Interview questions [1]
Question 1
Solve OLS/ridge regression in numpy - with gradient descent and closed form solution.
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.
I applied online. The process took 1 week. I interviewed at Amazon (Tokyo) in Apr 2026
Interview
The interview for the Applied Scientist position primarily focused on three core components: technical questions regarding machine learning, a live coding assessment, and a detailed review of my professional experience.
