Amazon Manager - Operations interview questions

4 rounds of behavioral interviews including a small case in one of the interviews. The first 2 interviews were 30 minutes each and the next 2 interviews were 45 minutes each. It is more of a conversation than an actual interview

They recruited me via LinkedIn. Then I sent in my resume and within two weeks was to go through two interviews. The phone interview was basic math with regards to how many pieces you could produce in with a given amount of employees, hours, and days. Then, if I had an increase of volume, how many more employees did I need based upon previous information. There was also many emails back and forth with corporate with them providing information and requesting information. The basics requested were phone numbers, address, another "updated" resume, willing to move our not, and other basics. Overall, not bad.
