Amazon Senior Project Manager interview questions

2 screen interviews back to back. Small case type questions -

Got an email saying my resume has been shortlisted. Replied back to the email specifying dates for a telephonic interview. Did not receive an acknowledgment email confirming the date. A day before the date that I had asked for got a confirmation email. There were 2 back to back telephonic interviews about personal goals, why do i fit into the role, some creative questions about amazon's business changes, explaining the past work situations. I do not know what constitutes right answer for these kind of questions and since its telephonic, it all depends on choice of words and brevity.
