Amazon Network Engineer interview questions

Amazon did an initial phone screen with me some months before - before deciding to ask me to travel to Dublin for a days worth of interviews. I did a number of interviews covering a wide range of issues within the area I'd be working. Sadly, despite the cost of travelling to Dublin to do the interview and the giving up of a day, the only feedback I got as to why an offer wasn't made was "cultural fit".

Amazon.com has a rigorous interview process. The whole process consisted of 3 phone interviews, where we went over things like path mtu discovery and the tcp state transition diagram. The in-person interview performed onsite in Seattle was rigorous and was partially a panel interview process, and partially one-on-one. The panel consisted of more TCP questions and network management/troubleshooting questions. I got the feeling that they did a lot of TCP debugging.
