Your facebook is a representation of you, but you know that. If you still have a MySpace page floating out their how does it look? What are you tweeting? In the hiring I have done, I have made an extra effort to “Google” the people we are serious about. Make sure your social network pages represent you well. What content are you tweeting? Videos are you posting? What pictures are on your facebook page, flickr, Google+? What can a semi-tech savvy employer learn about you from your blog?
These are all great tools to assist you in presenting yourself to an employer…and remember, they are looking at them whether you know they are looking or not. A personal webpage is a great resource for the job hunt but make sure it looks good, I would rather go without a webpage than have my info out there on a shotty looking site.
A simple search of me found everything from a personal website to twitter to an ebay profile. A good employer will do this because they know you represent them. Don’t misrepresent yourself because you are desperate to get work…Search yourself and clean it up or delete it.
