I applied through college or university. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Mar 2011
Interview
2 1:1 interviews, 45 minutes each. Asked only coding questions. The first person asked me to write code to find the height of a binary tree given the head node.
The other person asked questions about hashmaps, and how to write a function in C that converts a String containing numbers to an int.
