I interviewed for multiple universities for adult nursing. From my experience, it’s generally about your motivations and experience in the field, such as why do you want to become a nurse, or what prior experience you have with the field of nursing/healthcare, as well as scenario based questions such as how you would react in a certain medical situation.
I suggest getting a good grasp on the 6Cs of nursing, or have a general understanding of the NMC code. Good luck!
