Third phone screen: Software engineering (individual contributor position). This was a very comfortable interview for me. Mostly all technical and programming questions. I knew I had done well when I got off the phone. Between each phone screen, a few weeks would go by without hearing anything. I would wait at least a week and then politely email the recruiter about next steps. Each time, the recruiter would apologize for the delay and setup the next phase (which would usually be for the subsequent week). Treat those Amazon recruiters nicely - Amazon is going through a huge growth spurt right now and their recruiters have way too many positions to fill to give anyone individual attention. So if you get anxious, wait at least a week, and send very short and professional mails to the recruiters asking about next steps. They are good about following up to any email you send within a few days.
