Amazon Software Development Engineer/Test interview questions

A recruiter got my contact information from linked in and then emailed me if I was interested in working for Amazon.com. My answer was positive, and he setup a phone interview for me. This was phone interview for a SDET position with the kindle team. The interviewer was nice, she asked me few testing questions, one coding question, and she said recruiter will get back to me.

The interview was set up by the recruiter. After confirming the interview time, the recruiter sent a short list of possible areas where the interviewer might ask technical questions. They stated that the questions will be over OOP, coding, algorithm, and data structures.
