apprenticeship help

Hello,

i’m from northern ireland looking to do a degree apprenticeship in the uk. i’m looking to do radiography but i’m confused when it comes to the employment section on applications. when you are applying for apprenticeships at separate universities (instead of nhs job website), what sort of employment are you supposed to put in/have? is it within that chosen career path or is it just any job? or are you supposed to say the job your currently working then the uni provides you with work if your successful getting onto the apprenticeship? and if it’s supposed to be within the career path (for me radiography), where are you supposed to find such employment before you apply? thankyou
