Linkedin, the online CV networking website, has been able to change the way that staff are recruited by firms. Previously, jobs might be advertised in expensive forms of media, such as newspapers. Today, it is possible to add all your education and work experience to your profile. You can then network with colleagues, friends and other industry professionals. This way, you expand your contact list and might be able to link with people at other companies. Recruiters commonly contact potential employees direct, which can dramatically reduce recruitment costs for employers.
