Amazon Financial Analyst Intern interview questions

Had employee referral a couple months before response from recruiter. I was contacted by recruiter to set up 50 minute phone interview which was was both in depth behavioral and a decent amount of technical questions. Then invited to Amazon headquarters for two back to back 45 minute interviews. Ultimately heard back a week later.

Was contacted by a recruiter after handing in resume at a career fair. Invited straight to on site interview. Had to prepare a case on a M&A scenario, or inventory management. 4 rounds of 30 minute 1 on 1 interviews, two standard behavior, one "bad cop", and one bar raiser. Case assumptions will get challenged, but relatively straight forward
