I was given an online coding challenge with two questions. Your solution would have to pass 15 test cases. My solution passed the first 4 questions but failed the subsequent test cases.

First round with HR screening: 2 LeetCode questions, then HR manager screening, then the loop which consists of 4 interviews, each an hour long. The 4 interview questions they asked were: * Three medium LeetCode questions * One system design intervi

Good, long but straightforward. It has multiple stages. You can prepare for this online and from other sources. They are on time and very understanding. Know your design patterns and algorithms, and know how to communicate to Amazon's standards.
