If you are interviewing less than a dozen candidates a year then that probably means someone else in the organisation has already gone through a big pile of CVs to narrow it down to the 10-15 best candidates for you to interview. Having, briefly, sat at the start of that pipeline and seen 150+ reasonably relevant looking CVs (someone had already thrown out the very worst ones) roll in in a week for a fairly entry level programming position and having only a few hours spend to go from 150 to 10-15 candidates, you start making up some pretty arbitrary rules for throwing out CVs.
