As a Band 7 theatre nurse, your position will include working with patients during the preoperative, anesthesia, surgical, and recovery phases of their operation and procedure. This is very hands-on and highly skilled work, so your interviewer wants to hear you thoroughly discuss any nursing experience you have in this realm throughout your career. While they can likely see your overall experience from your CV, this is the time for you to elaborate on any experience you have in surgical preparation, assessing patients before procedures, preparing surgical equipment, and first assisting in the operating room.
