Entry-Level Jobs Going to Public State University Students

This somewhat brief article in a recent issue of the Wall Street Journal suggests that entry-level jobs in large companies are going to students who have graduated from large state schools, such as Texas A&M and University of Illinois (Urbana-Champaign). I'm not sure how reliable the study is, and the comments on the article bring up some major problems with the reporting in the article. However, one might see that it makes sense that large recruiting companies would make it easier on themselves to recruit from large state schools: to use crude economic terms, public universities are going to provide greater supply to meet the corporate demand. But this article does raise the question of whether larger state schools really do train their students with the "practical skills" they need for entry-level jobs better than elite liberal arts schools or Ivy League universities. Are the educations received at state schools more "useful" or "utilitarian" than those received at smaller, private institutions?
