Hiring: medical assistants and aides in San Diego - what worked for you?

A home-care agency in San Diego is taking applications for aides with paid training. I have been trying to stay organised about it. Shifts range from mornings to overnight. Do any of these pay for certification?

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
