Dianuj was successful in finding a job through doing voluntary work and I will say that that is a good route to try.
Also, sign up for bank-work at your local hospital as that will give you a foot in the door, so to speak.
Don't be put off by not being called for interviews or not being successful at interviews because it will be good experience for you.
It won't hurt for you to apply for jobs even though you might not meet all of the requirements because your CV may make you considered to be worthy for an 'outside chance'.
Always give additional information about yourself in the application and also contact the department for a chat or even arrange a visit to see them.
We only require candidates to do a couple of very basic pratical tests because, in our experience, it's the basics that candidates fall down on.
Cheers
