Social media sites such as Facebook, Twitter and LinkedIn has been front and center on many job hunters. Most likely if you have made some forays into these areas already. While many people are getting success by using these social sites into their job search strategy, if you have little experience using these sites, you might not know from where to begin. It is better if you decide your overall purpose before jumping into these social media sites. Recently Shama Hyder, social media expert and CEO of the Internet marketing firm, said in her interview, Click-to-Client, advises job hunters to first start with a focus. The biggest mistake she found in people that they just post their profiles on these social media sites without having any future employer in their mind. So It is better if you start with a purposeful profile and think from the perspective of what overall first impression that employer will have of you. Hyder suggests only listing interests that support or underscore your purpose.
