A great place to work if you are in a software development role - Software Development Engineer In Test II Amazon Employee Review

You get to work with some of the smartest people in the industry. The environment is very competitive, you would stand out as a sore thumb if you are not performing as well as the others. The work is quite interesting depending on what aspect of Amazon you are working on. You get to work with latest technologies in the field. You are expected to be a self starter and have the ability to learn on the job and adapt to rapidly changing work priorities. You should be flexible with your work hours as you might be working weekend when the work is real crazy.
