Amazon Area Manager interview questions

4 panel pod interview. Each interviewer was from a different area of the company...HR, Statistics, General Manager, and Sr Operations. The interview was fairly easy. I didn't do well on the second part of the workflow math question.

Two 45 min interviews and a math assessment. They try to be "laid back" while throwing in backhanded snarky comments. The two interviewers seemed almost like a "good cop, bad cop" way of doing things. One seemed pleased with my answers and the other kept digging at everything they could. Probably some type of "test" in their eyes.
