Be careful what you share here. The interviewers want to know why you want to pursue a degree with them. Share your knowledge of what makes them prestigious or how they stand out from other universities with similar programs. Don't suggest that you were simply playing the numbers game, trying to get accepted somewhere. Convey that they're your top choice, that your values and mission statements align with theirs, along with any other considerations you put into your application. Convince them that Midwestern is the university for you.
