Most of us think that being former applicants gives us a leg up on the guy or gal who's "faking" an application, but truth be told, most non-student admissions officers are up to speed on the tricks of the trade, so to speak. Other than being an extra set of hands, I didn't see how my role on a med school admissions committee was any different from the other officers. I voted just the same, and I evaluated applicants similarly.
Going into it I thought that I would be able to pick out the "fakers" and application padders, but it's not always so cut and dry. I found it extremely difficult to pick out a class of 180 from a pool of nearly 4,500 by just reading someone's application.
It's an enjoyable experience because you feel like you're helping to pick a class of superstars, but when you think of the thousands of applications that will fall to the axe because of your decision, you feel kind of crappy. It's a tough job, but it would give anyone tremendous insight into the way a med school class is selected. It's a lot more "hit or miss" than most think.
