It sounds simple, but the best thing to do is to apply! Applications are accepted every day and they are screened by a person, not a piece of software. If you have transferable skills, make sure to create a cover letter and tell us how your skills may fit our needs.
To get a foot in the door, try volunteering. Porter Hills has many volunteering options from a few hours a month to as much as you can handle. It is very common for someone to volunteer, start getting to know some names and faces, and when an opening comes up, they are in a great position to apply and be strongly considered for employment!
