The process took 3 weeks. I interviewed at Amazon (Seattle, WA) in Nov 2010
Interview
The first conversation was just a phone conversation with a recruiter to talk about the position. A week later, I had a phone interview that was mostly focused around me explaining my skills and current job and it included one programming question. I had a second interview a couple of weeks later, also over the phone, that was entirely focused around programming using a site to let the recruiter see me code solutions to various problems. She did a poor job of explaining the problem and, when asked specific questions, was unable to explain what she was really looking for. After I completed a solution to one problem, she realized that she forgot to tell me all of the requirements, so my solution didn't work. When I asked her about the position, she didn't know anything.
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.
Interview questions [1]
Question 1
tell me about a time you took responsibility beyond your role
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.
