I applied through an employee referral. The process took 2 months. I interviewed at Amazon (Herndon, VA) in Sep 2014
Interview
3/4 interviews. 2 phone screens and possibly an on-site. 1st phone screen basic networking questions. Second one into Linux/Windows. Interview process is very slow. Keep on applying and don't rely on Amazon only. They are hiring all the time so the interview process is tidious. They will reschedule the interview and take their own time.
Interview questions [1]
Question 1
Interview was fairly ok. You must prepare well in basics even terms like TCP/IP window size and packet header. Must know Linux scripting, Active directory, LDAP, 'grep' command.
It was a 4 round loop. The first two rounds focused on networking and troubleshooting, plus questions about your domain. The last two rounds are just answering questions using leadership principles in STAR format.
The interview was smooth. Recruiter reached out with an invitation to an online assessment, then a phone interview 1 hour and interview loop scheduled after that. It had 4 rounds

Depends on the domain of the role. I had Networking domain, so most questions were on Linux and troubleshooting.
It was difficult , questions about os and computer network and one easy coding question , the coding question was prime number question, also asked behavioural questions which are to be answered in STAR format
