First of all, the headhunting industry charges only one party, and absolutely does not charge individuals; it only charges companies. A common person might ask, why don't these companies post job openings on specialized recruitment websites instead of paying headhunting firms to help find candidates? Actually, this is quite simple. Posting on a website also incurs a fee, and while companies may receive a large number of resumes this way, those with actual value are few, especially for very senior positions. Have you ever seen many managers or top-level executives go on 51job or ChinaHR? Moreover, many excellent talents in companies may not have a strong motivation to switch jobs unless they encounter a position that is extremely attractive, which would make them consider it. Additionally, some roles are complex and cannot be simply defined by programming experience; they require many extra conditions that need to be understood by the headhunters.
