Yeah, I was sort of leading the witness with those questions, because what you've said is undeniably true, and anyone with a brain can pretty easily come to that conclusion. Especially in our business, is the Naval Academy or Princeton grad any more capable than the Ohio State or Texas A&M grad (though the A&M grad will certainly be the most obnoxious about his alma mater)? Of course not. They're all 2ndLts who have to figure it out the hard way. There's no standardized testing as a platoon commander for which you can study all night and day and get a 100%. But when it comes time to transition (careers, not genders) the former have an undeniable advantage, probably due to either the prestige/shock factor or alumni network, or a combination of the two.
I've known Community College grads who I would pick to be on my team every day of the week, and Harvard grads who were so infatuated with their own intelligence that they didn't even care to know their Marines' names. And vice versa. Not to mention degree program. In no universe is chemical engineering at the University of Georgia easier or less meaningful than a Philosophy degree from Yale (obviously). But I'd be interested to see a study comparing like-degree programs from a state school and a top 10 Ivy. I'm not sure what they would "measure" in terms of actual career field effectiveness, but I'm sure it could be done. Or even just interviews with Fortune 500 CEOs to see if the recruiting factors actually translate over to success factors once those individuals are hired.
Disclaimer: I barely passed state college so if you're thinking I'm just a dumb, bitter, liberal-arts-degree holder that just needed a piece of paper in order to commission, you're probably not ENTIRELY wrong.
