Recruiters work as advocates for companies, convincing employees to choose them in a competitive market. They actively discuss the merits of companies for potential employees that might have multiple options. They are typically involved in organizing events for these potential employees. Their job is to be positive about the company and to serve as an informational contact for employees.
Skillset: Recruiters have to be able and willing to sell on behalf of the company. For this reason, they must have a background in marketing or sales. They must have strong communication skills, too, in order to deliver the message of the company. These things combine to make up the recruiter skillset.
Education: Many recruiters will study marketing in their undergraduate college. Some will go through a sales or human resource management program. These jobs are generally not populated with people who hold advanced degrees. A person who wanted to get ahead could do so with a masters degree in a related field, though.
Career Path: Building a career as a recruiter requires one to sell and communicate. This is one of the reasons why advertising, marketing and business backgrounds are so important. A communications or marketing degree will help a recruiter go far. Recruiters typically march up the ladder to additional HR positions.
