Interview Question

I went for a job interview today at a Prison. It's a great job and a great place. I was surprised, however, that they didn't seem to care what my attitude was towards the patients. If I cared or not. They were purely technical. I was surprised. Also, I was told that they didn't have a union for LVN's. I recall that the recruiter said we did. So I fired off an email to the recruiter asking about this, and she said that, in fact, we do, and told me what union it was and the State website to go on to see for myself. Why in the world wouldn't interviewers know somethng like that? I hope I get the job, but the interview left a slightly bad taste in my mouth.
