Hiring: medical assistants and aides in St. Louis - first time posting

A home-care agency in St. Louis is taking applications for aides with paid training. I do not usually post, so bear with me. They mention tuition help for people who want to train further. 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.
