Perguntas de entrevista de vagas de Manager - Network Operations da empresa Amazon

Initial screening done online. Followed with a phone interview. Feedback was difficult to obtain, followed up a number of times and details could not be found. After a few weeks of trying and still no details to be found someone just stated that I was not selected. No details provided as to why, which was quite strange and have not experienced that answer before in my career. They couldn't even confirm my name?!
