Not having a social media presence is seen as shady. Many companies not only require you to use social media, they require you post everything publicly so they can see it or make you "friend" their HR manager.
They use this to screen potential hires to see if they engage in anything that might make the company look bad or be liable at some point in the future.
Millions of people have been rejected from jobs because they don't have Facebook, or their Facebook account contains too few posts, or they posted a picture of themselves drinking at a party and that's an indicator of a risk that the company would rather not deal with.
