I applied online. I interviewed at Amazon (Seattle, WA) in Feb 2013
Interview
There are two phones calls. One is from the team technical person, the another is from HR. The first man asked me 2 programming problems, and the sencond man asked about my background and projects, then he also asked me a programming problem.
Two of the three programming problems are
1. Reverse evey word in a sentence, for example, reverse "How are you." to "woh era uoy.", including the dot.
2. remove duplicate chars in a char sequences.
