I applied through an employee referral. The process took 72 days from application to rejection email. The process consisted of an initial first interview with one of the engineers on the team, which included a programming challenge (Leetcode 200: Number of Islands), some questions about my experience and background, and some questions about deadlocks and the hardware architecture of a system I worked on. After passing this, I was moved onto the final interview loop, which included four hour-long interviews with the team and hiring manager, which include two Leetcode hard questions, one question on designing a dynamic array, a system design question, and a bunch of questions on the following Amazon leadership principles: Dive Deep Deliver Results Customer Obsession Ownership Disagree and Commit Bias for Action Insist on High Standards Learn and Be Curious I thought the interviews overall went pretty well and I was surprised to receive a generic rejection email three days afterwards. I will likely not being applying to Amazon again. The recruiters were very supportive and responsive. However, the process was too long and I received no feedback on why I was rejected, so I can't justify going through it again.
