Really? I've been at the same job since college and they just had my transcript, in-person interview, and drug test results. Social media doesn't come up in any interviews. Maybe HR searches for obvious red flags via Google, but not that I'm aware of. I don't work in software though. Is it really that common when applying for software positions?
