I applied through college or university. The process took 1 day. I interviewed at Amazon in Mar 2013
Interview
It started from a campus recruiting process for finding summer SE interns. The interview consisted of 2 sections, in which I interacted with an Amazon.com's recruiter in each section alone.
First section: Tree Traversal
I was asked about the best implementation for a binary tree (i.e. pre-order, in-order, post-order). I was required to communicate reasons why I chose to use a particular one.
Second section: Iterative and Recursive Arithmetic Implementation
I was asked to find sums of next N numbers in an array iteratively and recursively. I came out with the iterative approach within a short period of time, and the recruiter asked for the recursive approach.
Note: The recruiters asked questions unrelated to programming too. For instance, they asked the reasons why I chose Amazon.com as a candidate company for my internship. They wanted to see my thoughts
Hackerrank round first and then two LC questions as the final round (BFS/DFS medium). Also had a behaviour component, testing the leadership principles and how my experiences aligned with them.
Expect one behavioral LP question followed by a leetcode medium or hard for two rounds. Be prepared to answer in depth on the behavioral questions and review LeetCode’s list of questions from Amazon.

HR interview, then I had 1 45 minute coding round with 10 minutes behavioral and 35 minutes coding. Behavioral round was typical star format questions probing at leadership principles. Ex. Tell me about a time you took initiative and it didn’t work out.
