Stanford Health Care Facilities Engineering Manager interview questions

The phone interview was straight forward. The operations manager went over my resume and work experience. Most of the conversation revolved around what I am seeking and why I am planning to move from my current job. Although, I had applied for a Facilities and Engineering Manager position the Ops Manager interviewed me for Facility Manager position instead. Perhaps there was an error in the system. I am not sure how the back end is set up. But the Ops Manager was able to answer my questions related to the confusion about positions.
