Imagine, then, the fear inspired in every high school senior by the word "optional" on a college application. You don't need an interview--it's "optional." If I'm the only one who doesn't do the "optional" piece, I'll really look terrible. For example, many if not most, "optional" interviews are non-evaluative and therefore don't really count. You don't really have much to lose.
