5. Oversharing
While this is certainly pest-worthy behavior, oversharingthat is, telling everyone every little thing you're doing, thinking, reading, watching, listening tocan be a big problem, even for the non-job seeker. Not only are your friends and family on your social networks, your future coworkers and supervisors are there, too.
Try to tailor your social media conversations to those people, rather than your friends and family. If your friends and family are the types who want to know every intimate detail of your life (hint: they're not), share it via email, not your networks.
If you can just follow some basic professional etiquette, you'll find you'll get a much better response from the people you're trying to impress, rather than if you drop your guard and post things you shouldn't.
