If you are unsure about a specific job role you may wish to contact the employer direct and ask further questions about the job, what the role entails and their expectations. It will also help give you a feel about what the employer is like to work for.
You may also wish to speak to a careers advisor. A careers advisor can provide you with information about job roles in the care sector, the qualifications or training you may need and how much you can expect to be paid.
