Amazon Software Development Engineer II interview questions

I was contacted by a recruiter the day after I applied through the Amazon careers page, and he booked a phone interview with a hiring manager. The interview was 1 hour long. It started with my experiences and for the coding part I was asked to solve a problem that involves some data structures.

Asked for a 90 minute phone interview after finding my resume online. The call followed the pattern described by others here. There were several technical questions of medium difficulty. I was asked to write code for one in the language of my choice using a shared web page. There was also a general discussion of an OO modelling problem. There were no surprises or gotchas. The interviewer was not trying to be tricky. It was like an discussion you might have at work about solving any problem.
