Have you ever had a stack for 100 resumes and had to figure out who to interview for the one position? You need to get rid of at least 80% quickly before it is worth your while to read them in more detail - that still leaves 20 to read, but that is way too much, now you are just looking for people who can probably do the job or meets any diversity requirements HR might have (and would be better, but you will interview anyone who lets you prove to HR you tried before hiring whoever comes out on top).
