Careers fairs give you the chance to meet employers face-to-face, and to learn about current vacancies and opportunities available. The recruiters are trying to market their organisations to you. However, the fairs are also an opportunity for you to market yourself to potential employers. Often the stands will be manned by graduate recruitment staff and / or senior managers, who may also review future applications. They may remember meeting you at the fair, and so making a positive impression may help you make a later, successful application. If you’ve been particularly impressive they may even ask for your name and contact details, and watch out for your name as applications come in. Source: http://goo.gl/TuFxzi
