I got asked what some of the different administration methods are so it might be worth being aware of some of the different ones.
E.g.
Oral, transdermal (through the skin), IV, intramuscular, subcutaneous, rectal (yes you can say rectum and any other words for it so don’t be scared), sublingual (under the tongue) have a google of them so you have a rough idea even if they don’t ask you’ll have to learn it eventually anyways.
Be yourself, confident and take a little time to think about your answers and if you don’t know just say you’re not sure. The interviewers are really nice and will help guide you if they’re asking academic questions as opposed to questions about yourself.
Good luck!
