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

Several clinics and a hospital near Omaha are hiring medical assistants, patient-care techs and schedulers. This is my first time dealing with any of this. Shifts range from mornings to overnight. What is the interview process like?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
