Healthcare support jobs hiring around Boston (update)

Several clinics and a hospital near Boston 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. Do any of these pay for certification?

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

Ask about overtime and shift differentials. The hourly rate does not tell the whole story.
