Amazon Operation Manager interview questions

Several online interviews. Asked extensive questions, math question during interview, white paper required prior to interview. Overall good experience. The interviews were on the same day, the follow up was within 48 hrs. and received via email

One screening interview followed by four face-to-face interviews. Interviews at this level were with senior individuals - Ops, Finance and HR. Full on but you can prepare as it is a competency based question approach.
