Amazon Web Developer Engineer interview questions

I applied throught the amazon carrers page, I was contacted by email and they scheduled a phone interview, it was a technical filter. They were very fast, the only thing I didn't like is that I didn't get any feedback after the interview. These guys are hard to please, however they were very professional at all times.

Applied online via advertised section of indeed.com listed as for Kindle Store but turned out to be for Fire Phone. Took only 2 days for HR representative to get in touch to set up a phone interview with the project team. Over the phone & web, went through series of technical questions including actual coding.
