Amazon Senior Project Manager interview questions

Numerical test, then phone interview. Somebody called me from another country, she wasn't an HR, but more like a call centre agent that was asking me pre-selected questions like a robot, and recording my answers in an extremely mechanical way, always looking to hear the famous principles. Most hilariouos interview I have ever had, as well as the worst. After that, no hear back after 2 emails sent to the recruiter asking for updates. They don't even bother sending a rejection email. People are treated like cattle.
