First interview in the Aesthetics field!

Hi everyone. I have finally recieved a call back to interview for a position as a RN in the cosmetics field! I've been trying to enter this specialty but have found it a bit challenging for someone with no experience in Aestetics. The positing was a little discrete, but listed a search for clinical support for vascular and cosmetic procedures. I've done my research about the company and the procedures they do, etc. Any tips for a successful interview here? Any questions I should ask?
