Well so many things comes to mind when thinking about this kind of guarantee. Location is one for example. If I am willing to live and work in Chicago but Udacity found me the job in Sacramento, CA will I be willing to move to CA. I don't think so and that makes me the potential candidate where my fee won't be refunded as I say NO to the job offering based on the preference of the city I choose to work/live in.
