beside being in the top 2%...
I don't think the OP really gets what mensa is or what it takes to become a member (whether s/he is a member or not).
I don't think it 'screams' anything, although many insecure folks might take it that way.
A basketball player would probably list their height on their stats/resume - it's a validated, measurable aspect of their biology. IQ tests are as well, and mensa membership is one signal of that measure.
It doesn't mean that you will definitely be a total success at any job requiring brainpower, but it's certainly an indicator. People might read a lot more in to it than you intend, but... you can't anticipate every possible objection anyone might have and just leave parts of your life off. If you put a certain school down, people might think it "screams" that you're some sort of elitist, for example. Do you leave that off? It's harder to get in to mensa that it is to get in to most universities.
Your motivation to go to a small club with alleged higher intelligence might also be a signal and one that a lot of recruiters/companies dislike.
Then you better not put it on your resume.
People list stats that are relevant to the job they're applying for. Why would a Mensa membership be relevant? Members of Mensa are known to be better programmers? If not, putting it down as if you think it is relevant somehow can give a bad impression.

When you know about a common objection in advance it's not a smart thing to do...
If Mensa was set up as an open competition which everybody (or at least a majority) participated in, then it would have more credibility.
At the moment most people are fine with the idea of Mensa as a club, but not as a guild of "special people".
I've been a dues-paying member for years but don't go to the meetings (who has the time?) and the monthly magazine/newsletter is terrible. The AG is even in-state this year for me (Florida), but I don't plan on going.
I already 'knew' I could get in because I had the appropriate test scores, but actually applying and paying the dues... I went through the process.
Went to a few meetings, but generally lame (well, the dinners were). You don't have much in-common with folks. I view the IQ stuff as inherently biological - it's sort of like joining a "tall persons" club, or a group of left-handed people. It's a rare biological condition, but not much you can do about it.
I was a bit hungover when I took the test, but I managed to pass (at least when I took the Mensa membership test, you were not told your resulting IQ 'score', you were only told whether or not you achieved the minimum to qualify for membership).
