Would adding Mensa to your resume really help you get a job? I talked to a hiring manager friend about this a while ago and he felt adding things like that don't make sense unless you have some achievement related to Mensa. One caveat - he wasn't in the tech industry.
IQ is strongly correlated with job performance, so yeah, providing evidence that you're in the top 2% by IQ is a really valuable indicator.
My Dad was in Mensa, and reading their national magazine as a kid I was not exactly ever inclined to join, but as a quantifiable, generally useful piece of evidence about a candidate it's pretty hard to beat.
