On-campus interviews are a gift. They will be by far the easiest interviews for you to find. Since they are "free" interviews, many students approach on-campus interviewing with little advance thought or preparation. As often happens, when something is given away for free, it has little perceived value. Be careful, however, that you spend this free resource wisely. On-campus interviewing is a once-in-a-lifetime activity. You will never again in your job search be granted the opportunity to simply "sign up" for interviews. Planning allows you to maximize this opportunity.
