You said AMA so I am going to ask again- what is the actual NHS job? “Admin booking in patients” could be any number of things. Is it in a hospital, a GP surgery, a specialist diagnostic service? Nationwide admin or a local area? Big team, small team, WFH, in an office? Liaising with clinical staff in person, working in a team of administrators, managing any more junior staff?
You may as well have said “I’m going to work in a shop”, it’s that vague.
