I applied through an employee referral. I interviewed at Amazon in Oct 2022
Interview
I got referred by an internal employee. Then within a week I got contacted to start the interview process with an online assessment (2 medium-level leetcode problems). Now I am going to the second round which is a 60min interview with someone of the Applied Science team, covering science breadth and depth questions and behavioral questions.

What is serialization?
I applied online. The process took 4 weeks. I interviewed at Amazon (San Diego, CA) in Jan 2025

Two back to back interviews focussed on breadth followed by depth covering pretty much the entire landscape of machine learning. They also have a lot of Leadership principles questions embedded into the interview. The challenging part is the breadth expectation.
