Amazon Sr. Project Manager interview questions

I had 5 interviews with the, each almost an hour. It was a behavioral interview, probing on fit questions. I was asked to go deeper into every question and answer. It was long and draining.

I was approached through LinkedIn for an interview as they were doing a hiring event in my City (I am not US based). This was followed by some negotiation for finding a time for a phone interview (time differences are always a challenge). The actual phone interview went very well and at the end she said that she would like to send me some written questions and she needed my email address. I opted to email her so she could email me back - been a couple of weeks now with total radio silence. Not sure if this is just the way they do things or if I should take a hint. Either way I have attempted a few follow ups and have been left in the dark.
