Volunteering at NYC Health + Hospitals interview questions

I've scheduled an interview with one of the Volunteer directors but I'm not sure what they would ask and how to prepare. Has anyone else also interviewed with them? Do they just ask basic questions like why you're interested or is there more to that? This is the first interview ive ever had so im pretty nervous even if its really short (like around 15-20 minutes). Thanks in advance
