Multiple acceptances?

I have a question that may seem kind of silly and stupid, but I can't find clear answers online. Hypothetically, let's say an applicant interviewed at a school in September, and was notified of their acceptance at said school by October. However, let's say the applicant still has other interviews scheduled, or is hoping to get more interviews. Would this applicant "accept" the admissions offer and send in a deposit? Would they then be able to get this deposit refunded if they were... Multiple acceptances?
