The interviewers want to know that you have thought out all options and scenarios if you are not accepted to Temple University. Your answer to this question should also show the interviewers that your interest in the healthcare field goes deeper than your acceptance into pharmacy school. If you are not accepted, show that you will take a different path as a pharmaceutical assistant or sales representative, for instance.
Alternatively, you can let the interviewers know that one rejection won't stop you at all! Talk about your plan to reapply if rejected. Whatever path you choose, you must show the interviewers you have confidence and drive. It'll take more than one rejection to keep you down!
