I got a screening from an HR representative roughly a month after applying which included taking a Linux knowledge test. The first phone interview was set up for a few days after that. It lasted about an hour and consisted mostly of technical questions dealing with Linux commands, DNS, and general networking. There were also various troubleshooting scenarios. The second interview took place a couple weeks later and followed the same structure. After this interview, I did not hear anything from Amazon for almost 3 weeks. I emailed them and one of the HR reps told me he will update me with the status soon after checking on where they were at with it. A couple more weeks gone by, heard nothing. I am assuming if they just stop keeping in contact with you, you might as well just look elsewhere.
