Plan on finding out more about each school and then limiting the number of applications you'll send out. You'll save oodles on applications and trips and avoid a bunch of phonecalls and invites for interviews you aren't going to take. Podiatry schools do not know if you are interested in them or just applying everywhere. They don't know they are your second, third, 7th choice. They offer interviews to everyone because that's the only way to find out if you are interested in them. This isn't like medicine where people apply to a large number of schools hoping to secure interviews to a handful. Most people could eliminate schools straight from the get-go by just asking "would I want to live in that city". This is not a competitive process. If through some anti-miracle you can't secure an acceptance after interviewing at 2-3 schools then there is something glaringly wrong about your application or your personality. If you can't secure an interview after applying to a few schools you can always send out more applications.
