Gentiva Office Manager interview questions

I received a late in the evening phone call. The person was extremely rude and they wanted me to come in the next morning for an interview with no notice. I had already had an interview scheduled and told them that I could come in on Monday. They said they would call me the next day to arrange for the Monday interview. Monday came and went and I never got a call back. I called back and left a message and they never returned my call. A total waste of time. Very unprofessional, never apologized for calling after 7PM.
