Amazon IT Support Engineer interview questions

During the Interviewing process, you were first greeted by the hiring manager. Keep in mind there are other candidates interviewing at the same time. You spend about 3 hours interviewing with 3 different employees from Amazon. They asked the same technical questions from the initial phone screen interview and a lot of their questions are based on the leadership principles. At the end of the interview, the hiring manager didn't even have the common courtesy to walk us out the door without even saying goodbye at the least. Instead, the hiring manager had an intern walk us out. For a company that focuses on "Customer Service", the hiring manager seemed to lack that quality.
