Head-hunters. A head-hunter can be an individual or an entire employment agency whose job it is to find potential employees for a company. This company has hired them specifically for this task. They are the middle man that connects the employer to the employee. A pro with head-hunters is that you do little of the work. They are the ones that connect you to your potential boss. Head-hunters are most commonly used to find applicants to fill executive positions, so the con would be unless you are applying to a high end position this particular resource may not be available to you.
