Are you selling your CV?
HOW CONFIDENTIAL IS YOUR APPLICATION? Do you apply for jobs on job boards, the popular ones and not so recognised ones?
Did you know that recruiters and employers can buy your CV from these job boards? They pay a fee which entitles them to search a candidate by name or designation or even company.
Yes, your current employer can find you there and see when you registered your CV!
Be careful not to post your CV everywhere, be selective and cautious.
