Amazon Operations Manager - Fulfillment interview questions

I was contacted by a recruiter to apply for an Ops Mgr in a new fulfillment center. It took about two weeks to get scheduled for a phone interview. I got two days notice for the call. The guy I was interviewed by was almost half my age and a process engineer. I was told prior to the interview that Amazon was looking for strong leadership in this role. All of the questions revolved around process improvement and wanting to hear statistical results of process improvement efforts. It was a bit aggravating in that I do not have a background in formal process improvement, nor does my resume imply that I do. There were no inquiries about leadership, problem solving (other than the basic algebra problems the guy lead with). I answered the three behavioral interview questions in the STAR format. But, this guy did not understand my answers as I do not come from his background. It was like we were speaking two different languages. I am sure he had been groomed for process improvement, lean, six sigma in his few short years. I have a more holistic and varied career that he could not relate too. It was clear that Amazon is not interested in leadership as much as they are interested in management of the numbers. I can see why they are having issues with their workers.
