The Amazon.com interview process was somewhat long, but very thorough. They started with a couple of 1-hour phone interviews with a couple of their Network Engineers, who worked through my resume and asked questions about what I'd done previously and what I was looking to do in the future. They then proceeded to ask me technical questions regarding the skills listed on my resume. I then advanced to an in-person interview, where they flew me up to Seattle and set up a full day of interviews, with went from about 10am through 4pm. They had me in a small conference room and rotated through about six different people to interview me, including network engineers, a Linux engineer, a software person and the team supervisor.
