Hiring: medical assistants and aides in Knoxville (update)

Several clinics and a hospital near Knoxville are hiring medical assistants, patient-care techs and schedulers. I have read a lot of threads here and could not find my exact situation. Some do not require prior experience for entry-level roles. Do any of these pay for certification?

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