The employee selection process usually starts with a manager or boss commissioning human resources to fill a new or vacant position. The manager must first decide what qualifications she desires in a job candidate. For example, should the person have a college degree, or how many years of relevant experience is necessary? Once the manager establishes the job requirements, the human resources department places ads in the local newspaper and online. Sometimes, human resources uses a headhunter find candidates, someone who often specializes in a certain field, such as sales.
