I realize that this certainly varies by school, but is there a pattern? Do most public schools put each new application at the bottom of the pile while private research schools filter for strong applicants, or something? @gyngyn said something recently about modern software playing a large role in late applicants' potential for review at a certain school. I'm interested in learning more about this. If they are filtered, are they picked out mostly by stats or can other factors also be "read" by softwares?
