I applied online. The process took 5 days. I interviewed at Amazon (Cleveland, OH) in Apr 2025
Interview
PhD student in computer science here. Background: 100+ citations on my 14 AI/ML research papers. 3 media coverage articles on me
I had amazon interview and there were 7 rounds of interviews with 2 initial rounds with Hr and senior data scientist.
2 initial round with HR and then with Senior Data scientist 1 presentation 6 rounds of interview with the team
Within those 6 rounds I was asked leetcode question difficulty was hard. I was able to solve the leetcode with no issue.
I had great interviews with all and I was expecting an offer letter. Sadly HR called me and said that they have moved with other candidate.
Hope they realize that it’s not nice that you put an candidate through several rounds of interview and just throw them out. Never going back to apply

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.
