Amazon Area Manager I interview questions

I applied online and was sent a set of basic questions about my experience and openness to relocation. I replied and 3 days later was informed that I had been moved to the next step and that another person would contact me to coordinate. 10 days later I received an email letting me know my interview time and date (2 days later), name of interviewer, and some instructions. The interviewer called on time and introduced himself as a senior operations manager for the company. He had started as an area manager and worked his way up in 5 years with the company. After his Bio he asked me about my current position and asked about a time that I had improved a process. He asked a few questions to get more details of my examples (did your supervisor like the improvement? Did the company implement the change to other departments? Etc.) and then asked if I had any questions for him. I asked a few questions about his years with the company and ability to move around within the company. He was nice, professional, and polite, but seemed a little disinterested. After answering my questions he said that he would submit his feedback to HR and I would hear something soon. As instructed in the coordinators email after 5 business days had gone by with no response (I waited 7 business days) I emailed my recruiter who sent me a rejection letter back same day.
