Amazon Customer Service (CSR) interview questions

The interview has 4 to 5 rounds. The 1st round consists of a basic English test. This is the screening test and most of them are on their way out in this round only. They don't reveal the selection criteria.

After sending the CV and passing an online test, I was contacted by email and phone by the HR manager to schedule a phone interview. The interview was divided into 4 parts: English test (I am an Italian mother-tongue speaker) about past professional experience, a guided business case, logical questions, and motivation. I was told that if I were successful, I would be contacted to schedule an in-house interview
