I had a tech screening/phone interview that lasted more than an hour, then a second phone interview that focused on culture and customer service. After those I was offered an opportunity to fly to California for an in-person interview. The in-person interview was a day-long affair and I met with five different people (Though one was via video conference.) I was there from 10-3. They arranged my air travel and hotel and gave me a per diem for food and transportation. The interview questions focused around the Amazon Leadership Principles and many of the questions seemed to be re-worded versions of the same question to get at the principle assignment of that particular interviewer. Everyone I met was very friendly and most seemed enthusiastic about working there. One was a bit more lackluster and admitted that the benefits weren't great and there was no provided lunch every day and no on-site gym. (Which I guess is more the norm in Silicon Valley, but not as much in the rest of the country. The job I was applying for was not in California so I didn't expect those perks.) Overall it was intense to interview with five people over the course of 5 hours, but once I was doing it, it didn't seem as overwhelming.
