Capistrano USD interview questions

It was the most bizarre interview I've ever had. I got called into an interview for the position of Instructional Aide and learned that it was for a subject that was completely irrelevant to me and not the subject I was told I would be interviewing for. There were 2 interviewers, the choral director, and a woman (I forgot her position) were so cold and did not smile once. I should have just left as soon as I found out the position was for something I hadn't even applied for.
