An executive search firm or "headhunter" are industry terms for a third-party recruiter who seeks out candidates often once normal recruitment efforts have failed. Headhunters are generally considered more aggressive than in-house recruiters or may have existing industry experience and contacts. They may use advanced sales techniques. They may also purchase expensive lists of names and job titles but more often will generate their own lists. They may arrange a meeting or a formal interview between their client and the candidate and will usually prepare the candidate for the interview, help negotiate the salary and conduct closure of the search. They are frequently members in good standing of industry trade groups and associations. Headhunters will often attend trade shows and other meetings nationally or even internationally that may be attended by potential candidates and hiring managers.
Headhunters are typically small operations that make high margins on candidate placements (sometimes more than 30% of the candidate’s annual compensation). Due to their higher costs, headhunters are usually employed to fill senior management and executive level roles. Headhunters are also used to recruit very specialized individuals; for example, in some fields, such as emerging scientific research areas, there may only be a handful of top-level professionals who are active in the field. In this case, since there are so few qualified candidates, it makes more sense to directly recruit them one-by-one, rather than advertise internationally for candidates. While in-house recruiters tend to attract candidates for specific jobs, headhunters will attract both candidates and actively seek them out as well. To do so, they may network, cultivate relationships with various companies, maintain large databases, purchase company directories or candidate lists and cold call prospective recruits.
