Why are you interested in our school/program?

"I like that your program has such a dedication to community outreach, and this is one area in which podiatry can really help the underserved. I've come to appreciate what participating in special screens and the like can do for a community, and I feel it is my obligation--and privilege--to contribute where I can."

They are looking for flattery here, so flatter your interviewer. Before the interview, look up what the 'Mission Statement' or 'Vision' reads on their website. Then simply state how you know their values are [such and such, paraphrasing their Mission Statement and/or Vision], and that their values align with yours. You can also cite what demographic population seems to predominate in their program and how that applies with what aspect of podiatry you're most interested in.

"I know that your program champions the underserved, and I feel that this demographic has the most need for services like podiatry. Therefore, your values align perfectly with my own."
