Walmart Manager, Operations interview questions

Interviewed with 3 people who would be reporting into the position, thought it went well. Then interviewed with 2 more people together which was good and 2 more people separately. One of them was the person who was in the position and was leaving for a career change. I thought it was odd and felt the position may have caused her to leave. She asked if I understood that Walmart was the number 1 retailer and said she has big feet with big shoes to fill. I felt that she was not confident I would be the right fit.
