Another job interview

I got a messege this week for a job interview. I was at my newest job, and my husband called. He said " you just got a call for an interview." I asked " From who, and what is the position?" He said told me it was a retirement home wanting to interview for a LPN DON position. He said they said on the messege that they received my resume from the rehab side. I had not applied for this position.
I had saw the ad in the newspaper, but didn't feel I would qualify, as I had no management experience. I called the woman back, and set up an interview. It's today at 11:30. I'm going to see what is involved. I'm not sure I can do it. I was hoping to be able to go get my hair cut and permed before hand, but no time for that. I have 2 hours before the interview and we are having an ice storm coming through.
I will post how the interview goes.
