What is it like working as a certified nursing assistant in a hospital?

I have an over-the-phone interview on Monday for a nursing assistant job at a hospital and I want to know what it is like before jumping into this. I've worked in nursing homes before but not in a hospital.
By the way, I already know what nursing assistants do as a job (seeing how I work in a nursing home as a nursing assistant), I just want to know if anyone here is a nursing assistant at one and if so do you like it? Or even if you know someone who has that job at a hospital and if they like it that would be great.
