Social media sites serve many purposes. Your employees go onto sites such as Facebook
and Twitter to communicate with friends. Your company may use to the sites for brand promotion and marketing, as well as to gather customer data. Like it or not, social media has become an integral part of our lives
. Still, there are some uses for social networks that many companies look past. For example, CareerBuilder recently enlisted the help of Harris Interactive to poll more than 2,000 hiring managers and human resources professionals to find out how they might be using social media in the workplace to hire new employees. And although many of don't access the social Web for finding employees, those who do can gather serious insight into candidates. As a CIO who is likely faced with doing a fair share of IT hiring throughout the year, social media afford you opportunities to learn about job candidates before they even step in your door. You might even be surprised to find out what folks are sharing on social networks behind their employers' back.
