Was initially contacted through e-mail by an Amazon recruiter who set up the initial phone interview. The first interview was with a project leader who worked on the front end/web design team. Most of the questions were about basic CS concepts (arrays, data types, hash tables). The main question involved designing a variation of the DOM with some specific requirements. Second phone screening was a bit more difficult. Was asked to describe some of the differences between Java and C++. Main question was how to efficiently find the most common 3-page path on a website given an arbitrarily large log file. Described the basic algorithm over the phone and was asked to code it up and submit it by the end of the day. Overall, the process was fun and challenging. Interviewers were friendly, but eager to "get down to business". I have received an offer for an in person interview, but have not yet finished the process as of this writing.
