Amazon Operations Manager interview questions

Few days after my online application, I received an email from a recruiter asking my availability for a brief conversation (initial phone screening). The recruiter was very punctual. The whole phone interview process lasted about 40 minutes. During the interview, the recruiter gave me various scenarios, following by series of questions. At the end of our conversation, the recruiter advised me to read through company's leadership principles to better prepare the follow-up interviews.
