I would probably take it out during rush, but that's just my opinion. (Think of recruitment as an interview, and would you wear the piercing to a job interview? An interview at a tatoo shop, yes, but an interview at a corporate office...perhaps it's best to err on the more conservative side).
I'm not a big fan of nose rings, but for the record, I prefer the "side of the nose" kind:

I do not like this kind at all (my niece has one and it repulses me to look at it)
