Santé interview questions

Great interview. Basic questions and then a short exam was given to test knowledge of what you know as a CNA. Hiring manager was nice lady. Ask unusual questions too (i.e. "If you could travel anywhere where would you go?") Got offer but had to decline because the compensation was not what i was looking for

Was spoken to on phone before interview, was turned down at issue that I drove 45 minutes for. Everything they asked was the same as the phone conversation. Why did I have to drive 45 minutes?
