Answer 2

I would maybe wear khakis and a polo, or something similar.  

I volunteered at Children's Hospital of Pittsburgh.  At my interview, they asked me about my education, why I wanted to be a volunteer, what are my strengths, weaknesses, what position I wanted to volunteer for, etc.

It will probably last under an hour.  Just be yourself and answer honestly.  You might want to have some questions in mind for your interviewer as well.  Good luck and keep doing great things.  People like you make the world a better place!
