I applied online. The process took 1 week. I interviewed at Amazon (Seattle, WA) in Nov 2024
Interview
For the phone interview, I had two medium-level SQL questions and one easy-to-medium leetcode-style Python question. They used a whiteboard instead of hack rank, so I didn't have a chance to test the code. Later there were one or two questions regarding the database system design, and some follow-ups of how to optimize it.
