9/25
I used to have Alpha Phi Omega on my resume when I was doing internships (read: for the first three years of membership), but since then I have found it to be no longer necessary to do so, as it was rather superfluous and wasted space on my resume for more relevant matters.
OTOH, if I was a fraternity officer and had learned skills necessary for the job I was seeking, that would be another matter altogether and I would toot my horn like crazy.
Slight aside: I don't care for folk who join GLOs solely to pad their resume; it indicates that either they didn't have the "game" necessary to get the job on their own merits and skills, or that they wanted to pimp the org because their employer might be a frat brother or sorority sister and they would get the hook up by default. I have met a LOT of Greeks who admitted to pledging for resume filler.
