(I'm not saying that working for a porn company is bad! Far from it. It just seems like it would be really difficult to break back into the corporate mainstream after working for a porn company due to the raised eyebrows during the screening process.)
The more difficult part is tolerating the passive-aggressive culture of "polite society" that exists at most "legitimate" companies. Porn company culture is very aggressive. At my current dull-corporation job it's almost a weekly occurrence where I want to tell my manager or someone else up the chain to fuck off and get out of my way, in regard to getting work done. Porn is the only industry I've worked in where an aggressive (tinged with a modicum of respect) attitude is rewarded. I hate the hypocrisy at large corporations who encourage "take initiative/leadership, get-it-done!" attitudes, but then push back when an employee actually does that.
The funny part was how curious everyone was about what went on there. I never really felt that much stigma about it from others...most of it was actually self generated. The other way I got past the potential stigma, though, was that I discussed how serious the business side was. The analytics we did, how much detailed knowledge we had about what downtime cost us, etc. Our HR training was done by lawyers, not consultants, because if the company got sued they were not going to get a sympathetic jury so I knew what what not to do as a manager there. That was actually pretty attractive to the VP of HR at my next company.
I'm not saying you won't find those that pass on you because of having porn on your resume but I don't think it's that big of an issue. As others have noted before most porn companies do business under a pseudonym that is innocent sounding and it's usually enough to get you past the screening that might filter if it said "Bang Bros" or whatever company it was.
The bigger issue is if you had school aged kids. They'd never have let me talk at career day. :-)
When asked by a recruiter for more portfolio I said "Well, there are more, but they're adult". Her response was "Wow, I've always wondered about who does those and how that all works!"
and:
"That must be great, you'd have all the passwords!"
Mind you, this is in the more liberal Australia.
My boss here in Brisbane keeps seriously considering getting into online adult services of some description. He also wants to build a weed dispensary web app, so we can launch the moment they legalise it!
Then cross-fingers hoping they find that description generic and boring enough that they don't Google it.
Either way, its turned out to be a total non-issue. I always used the innocuous name on my resume, but everybody generally already knew, and nobody cared. Seemed like most people I end up working with have worked there or have had a friend that did or hired someone that did at some point.
I was kind of surprised.
Most coworkers at companies I have worked at know what I have done in the past. Never had an issue. You don't bring it up at the office and you use calibration and gradually give out details and judge whether coworkers would be cool about it when talking to them outside of work.
Turned out I only looked for 2 weeks before finding a good job.
