They will employ just about anyone so if you can get an interview chances are you will get the job. You just need to pass the DBS check and have two references.
It's a fairly generic interview, asking questions around person centred care, cqc, 'what would you do if...' scenarios, and obviously flexibility. Be sure to check whether the service you are applying for has a lot of lone working and whether the service requires sleep ins or waking nights. Basically if you can't answer some of the questions and have worked in care, then the job probably isn't for you. If you've never worked in care before showing passion towards enabling independence and person centred care will work in your favour, and it will help if you do your research into some policies such as the mental health act, health and safety, and cqc - who are they and what do they do for care services. Know all that and you should be fine!
