Agreed. I don't have a Github, contribute to open source projects, go to conferences or meetups or any of that stuff on my off-time. When asked about it in interviews I tell them about the kind of projects I've done, and that's pretty much it. Its a straight forward agreement, I'll give my time and expertise (C/C++) and you'll pay me a fair amount. I'm not going to act like my life is all about programming because that would be a totally sad life in my opinion.
