Amazon Software Development Engineer interview questions

The AWS team is opening the new software development house in Sydney. I received phone interview notice after I submitted the online application. It started with the two round phone interviews, around 15 mins general talk and then focused on code interviews on collabedit.com. They are all around 1 hours each. Then I got into the in-house interview consisting of 3 phone interviews with engineers from Seattle, (I suppose it's a new team they haven't got enough engineers to do it), another 3 based in Australia two of them are from management team.
