The best-written CV is worthless if no one sees it!
In recent years it becomes increasingly popular to join the LinkedIn or Facebook social networking websites for professionals, where you may search for jobs and have your keyword-optimized, rich content profile with a current CV. Hiring managers use them more frequently to consult your profile and supplement or check against the CV you send along. If you do not have an account, create one and include your social media link(s) on your CV.
However, you should manage your online presence and eliminate any photos and statements that could reflect poorly on you. From an employer’s point of view, someone who emphasizes partying on a social networking site is not focused on jobs and those who post complaints about work or colleagues are less desirable candidates. The online CV should not include sensitive information as it could show a lack of respect for confidentiality and discretion.
