I applied through an employee referral. The process took 3 weeks. I interviewed at Amazon in June 2012
Interview
At most three phone interviews and 1 on-site interview (with all expenses paid). Each phone interview is with a different person from a different department.
Studying the interview questions posted here on Glassdoor will help you.
Phone Interview 1:
Why do you want to work for Amazon?
What is the hardest engineering problem you've faced? (Prepare for them to question you a lot about details)
How would you improve the Amazon website?
Questions about Java (difference between abstract and interface, etc.)
Write a program that computes the Fibonacci number that is less than or equal to a given number.
Phone Interview 2:
What is the hardest engineering problem you've faced? (Same as above, but different interviewer)
Do you know what a hash map is?
Big-O Questions (give an algorithm that is as time efficient as possible, no programming required)
1. How would you sort 1 million integers?
2. How would you make sure two lists had the exact same content with no regard to order?

Question 1
Write a program that computes the Fibonacci number that is less than or equal to a given number.
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.

Question 1

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.
