I have spent an embarrassing amount of time this year trying to hire an exceptional recent college graduate for an entry level sales position.
Have you considered that "exceptional" recent graduates from "upper tier" schools might not be interested in an "entry level sales position"? Because that sounds like a pretty crappy job, one with a long, flat, dull career trajectory, and perhaps better suited to a mediocre student from a middling tier school, or one with an associates degree or perhaps even a high school diploma. Maybe there are entry level sales gigs that require an Ivy league education but from your bare description this doesn't sound like one of those and anyway the skills that make a good salesman - which are chiefly people skills - they don't teach in school and probably couldn't anyway.
Which is itself part of the reason that the university system is in crisis. You think you need an over achieving graduate from a prestigious school to do a job that a generation ago any shlub was qualified for. Meanwhile recent college graduates - and not even exceptional graduates from upper tier schools, all of them - have been led to believe that their degrees entitle them to salaries both commensurate with the amount of money they've borrowed to purchase them and generous enough to maintain the lifestyles they've grown accustomed to while attaining them. Whereas the fact is that most professions do not require any particular training and certainly not a rigorous and expensive course of 4-year study that most people are too stupid to learn from anyway.
Here's an old saying I made up a few months ago:
Even the stupidest mule will learn to pull the plow if beaten righteously enough.
Freaking beautiful, right? A hundred years ago they'd have put me in the aphorism hall of fame for that one. Nowadays, bupkis. The fact is that it probably doesn't matter who you hire, as long as it isn't a uniquely stupid person or one with some sort of genetic malady. And from what school they graduated is important only to your own sense of ego. What really matters is how good you are with the whip.
