Walmart Manager, Operations interview questions

I applied on-line for an operations manger job at a distribution center and was called for an interview 3 days later (on a Saturday). The interview was 7 days after I applied on-line. My overall experience was very positive with the process. After I filled out the on-line application, I was directed to take and on-line DSM4 style management assessment. The total time to apply and take the assessment was about 40 minutes. The interview was with the two assistant managers of the distribution center and the HR manager. It was a three part interview, first I was asked to go over my relevant experience, next I was was asked 4 behavioral questions (2 each by the assistant mangers) with follow-up/clarifying questions by the HR manager. The four questions were read straight from sheets of paper. The third part of the interview was for me to ask questions of them. The third part was an open conversation between all of us and was very enjoyable. I felt they valued my leadership experience (retired military) but were concerned because I would have to "catch-up" with the Walmart systems and corporate lexicon. Total interview time was about 45 minutes. I was notified 5 days after the interview that they were going to hire from within but was asked to interview for an area manager job the next day.
