Hiring: medical assistants and aides in Honolulu - any advice?

Several clinics and a hospital near Honolulu are hiring medical assistants, patient-care techs and schedulers. I have read a lot of threads here and could not find my exact situation. They mention tuition help for people who want to train further. Do any of these pay for certification?

The interview was short and focused on how I handle stress. Be ready with a real example.
