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

A home-care agency in Pittsburgh is taking applications for aides with paid training. I have read a lot of threads here and could not find my exact situation. 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.
