Amazon Sr. Project Manager interview questions

About one month ago, I received inquiry from Amazon recruiter who saw my info on LinkedIn. Was very interested in the opportunity and had a great initial conversation with the recruiter. Was asked to send her a copy of my resume and told she would be sending me some additional information and I would be moving on to the next round and would be receiving a call to set up that appointment. Promptly sent my resume that same day and got radio silence. Followed up several times and now, a month later, still never received any communication, even to say something like we changed the direction and you are no longer being considered for the role. While I understand the volume of candidates at a place like Amazon, for a company that hangs its hat on the importance of customer experience, that same attention and guiding principles clearly don't carry over to their talent acquisition process.
