    Interview

    I applied online. First round is a coding interview where I was asked to code several normal technical puzzles. Also, Amazon require you to have a web camera for some reason. I guess they just want to make sure it is you who is writing the code. After the first round, Amazon would ask you to go to Seattle if you pass through the first round.

    Interview

    I applied through a staffing agency for SDET I position, Telephonic interview was conducted. As I was not aware of Amazon process much I couldn't prepare well. I got call from SDET II on scheduled time. She started asking about my current project, role in my project and difficulties I faced in that project.Then she gave me string problem, I had to write a method which should return count of numbers. EX: Input "AABC32DE4P%@23Pu" output should be 32+4+23 = 59 I explained an algorithm to solve this, She asked me to it, I coded in Java. I took little extra time to fine tune it. Then she asked me to write some test cases to test the above function, I gave around 10 test cases. After this round I got mail saying I got rejected. I felt lack of preparation and awareness about interview process reasons for rejection.

    I applied through a staffing agency. The process took 2 weeksinterviewed at Amazon.com (Chennai (India)) in April 2011.

    Interview

    It was pretty well organised. They gave a good overview of what is expected in the interview so that we can be prepared to take it. They concentrate more on problem solving and the data structures where though they don't expect you to immediately answer the questions they wanted to make a genuine try and valuate the approach.
