Confidentiality, would you disclose information to your neighbour about a resident for example?
Safeguarding, different types of abuse, physical, emotional, sexual, financial etc and what you would do if you suspected something or found bruises on a resident.
Flexibility to do shift work, including weekends and nights.
Willingness to undertake training eg nvq
Prevention of falls, importance of correct manual handling, potential issues with feeding, basic knowledge of medical issues such as stroke, dementia and how these can affect them.
Above all a willingness to learn, be part of a team, know when to escalate things to your team leader (abuse, Deteriorating health) and see the importance of treating residents as you would want your own parents / grandparents to be treated.
Be yourself (don't make to much of your degree etc) and I'm sure you'll be fine. Good luck!
