Amazon Operations Manager interview questions

Phone interview less than 30 min, have been invited to personal interview. Questions in line with amazon principles, basic math flow question that you have to answer while interviewer waits. I had three questions, got the initial math question correct and follow up math question as well. Interviewer was pleasant and personable.

Conducted the phone interview process and it is pretty straight forward. The ask you about yourself and your qualification. They ask you to explain why you would be a good fit for the company and what you will bring to the team. They ask you a mth flow question because this job is about logistics and number are important.
