Amazon Operations Research Scientist interview questions

I applied online in Spring 2017. The interview process lasted 2 months. 1 HR screening, 1 phone call with a Product Manager, 1 tech screening with the Director of FEDS and then on-site. The on-site interview included a presentation and five individual talks. The interviewers were extremely nice. The position required expertise in optimization and my background was not a good match. It was a great experience and I understood what I was lacking.

Email me then schedule a interview with HR. HR go through resume quickly. Then ask you do you have questions. Only spend 15 mins. I think he didn't like me.
