So many church members have told me that I'm lucky that I can hide my Mormon-ness on my resume. In fact, the only "church cred" I have is my temple recommend. No mission, no sealing, and, most visibly, no BYU.
I turned down a full scholarship at BYU to attend SAIS. Nonetheless, I maintain some tenuous links to BYU, even though I went to "Satan's University" (UC Berkeley) rather than "The Lord's University". I'm on the rolls, so to speak, for the BYU International Society, the BYU Management Society, the BYU Political Affairs Society, and I've donated to Women's Research Institute. I still keep in touch with some BYU profs who work on Morocco, Arabic, and Islam.
In the end, though, I'm glad I'm a Bear instead of a Cougar.
Maybe DC is exceptional in that people are super-conscious of where they went to school + there are a lot of Mo's here compared to other cities on the East Coast. I've heard a lot of stories about illegal questions provoked by seeing BYU on the resume. For this job I had BYU WRI on my resume down at the bottom under "affiliations" and the woman who interviewed me (now my boss) asked me what my association was...I think she was just surprised and curious.
I always feel a little weird when filling out those job apps that ask for your high school (seriously, HR depts need to quit doing that, no one gives a damn where I went to elementary school when I'm filling out an app for a senior engineering position!). There's no way to not sound like a Catholic (which, of course, I'm not) with names like "Holy Innocents Elementary School" and "Saint Joseph High School" on your resume.
I've often wondered if asking about my pre-college education violated the rule about non-discrimination based on religion. These days, I just leave that section blank, but it's more out of annoyance than any desire to hide where I come from.
I don't think my BYU or mission have caused any concern to potential hirers, but maybe my line of work is different that way. The resume item that always gets the most interest is Peace Corps. Maybe it balances things out for people.
