I applied through college or university. The process took 3 days. I interviewed at Amazon (Seattle, WA) in Dec 2011
Interview
4 Amazon recruiters came to my school for a week to host interviews with candidates who had been selected from online submissions. After the first interview, they called me back and said they wanted to continue the interview process, so I can back in the next two days for a grand total of 4 interviews - one with each of the recruiters. The recruiters were fair and asked questions which any graduating software engineer should be able to answer. They consisted mostly of technical questions involving data structures and binary trees in particular, with a couple personal questions mixed in, such as "what interests you about Amazon?" or "tell me about this project on your resume".

Question 1
Probably the most difficult question they asked me was, he put a binary tree on the whiteboard and I had to write a function that would find if the tree was symmetrical or not. Anyone who's familiar with data structures and recursion should be fine with this, just don't freak out when they propose the question.
I applied online. I interviewed at Amazon (Sydney)
Interview
I can't comment much. I submitted an application for the software engineer position, and not even a minute later, I received an auto rejection email from Amazon (never received an online assessment).
2 behavioral 2 coding not very difficult. Behavioral is tell me about a time you took responsibility beyond your role and biggest accomplishment. The process is exactly the guideline they posted for interview.

It was a 2-3 round process, depending on how your interview went, with increasingly hard DSA questions followed by some HR and behavioural questions. First round was mostly easy and medium leetcode, followed by medium and hard questions in the second round and above on more complex topics.
