I applied through a recruiter. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Apr 2011
Interview
The interviewer was friendly and started telling about amazon.com and later told me to explain about my background. Later ask me to describe challenging role faced in latest project. OOPS concepts, UML diagrams, and implementation of that diagram. Most of time where around the class diagram, implementation and some scenario based on the UML diagram. He asked me to design Company Organization UML diagram (include all methods) with following constraints:
1. Manager can have some manager or workers reporting to him
2. No body should report to workers
3. Include functionality like ADD, Search, Remove Employee (how and where you will implement these methods).
He told me that I can expect second round with hardcore coding.
