I'm currently being interviewed. Was called by an Amazon Recruiter. Evidently they found my resume on a job board. The recruiter exchange was all e-mail. I get the impression this person is more of an administrator of the process and the communication is only via e-mail.
I've had one phone screen so far with a second phone screen currently being arranged.
The first phone screen was basic technical questions to make sure I really do understand software, operating systems and optimization. Followed by some basic questions on program management processes. There was also an exchange on my background. Will post again after the 2nd phone screen.
