The process took 2 days. I interviewed at Amazon in Mar 2011
Interview
first had a phone interview question on identifying the largest palindrome given an array of ints
then went through an interview loop (asked about reversing a sentence, removing an element from a circular linked list, implementing a graph function to add a new edge)
I applied through college or university. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Sep 2011
Interview
Applied for the recent grad Software Developer position. I got an email about a month later stating I was selected for a phone interview. I was called at the exact time stated in the email. The interviewer had a strong accent and was hard to understand over the phone.
First, basic questions were asked such as why you wanted to work at Amazon, etc. Eventually went to technical questions, which since Java was my strong suit listed, was about Java. A bunch of things about OOP and Java specifics: inheritance, interfaces and abstract classes, difference between final, finally and finalizer, etc.
Then I was given a coding problem. This part was kind of awkward. I was told to put the phone down for a few minutes and code, then read the code back to him over the phone. So imagine reading code over the phone: int, functionName, left parentheses, int x, right parentheses, open curly brace....
Anyway, I was emailed 3 days later stating I was not selected. Overall, the phone interview was not difficult. Just brush up on what you learned before.

Question 1
What is a hash table and what would you use it for?
I applied through a recruiter. The process took 2 days. I interviewed at Amazon in May 2011
Interview
Hiring process consisted of a phone screen and a series of in-person interviews in New York, New York. The phone screen took place with a Human Resources representative that examined my overall background for fit with the position available, Software Development Engineer with the Global Optimization Engine Team. I was then invited to New York, New York where I met where I had four one-on-one interviews (1 in the morning, 3 in the afternoon). The interviews were a mix of skills assessments (background in object oriented programming, data structures, algorithms) as well as personality assessments for fit within the team. Overall, the interviews were challenging (borderline difficult), but maintaining one's composure proves helpful in my opinion...after all, your response to stress is being evaluated as well.
