Interview as New Grad coming up with the Health Department..Any advice, Suggestions?

I have an interview on Monday as a new graduate nurse with the Health Department/Womens Services. Does anyone have any experience with the health department or what to expect? Is it a good place for new grads? I was let go from a job after being on 90 day trial due to them saying I was not catching up on my skills quickly enough. That has been over 8 months ago. I am nervous, anxious, and excited!

Any advice?
