Archadian is a specialized recruitment service used to source candidates for senior, executive or other highly specialised positions in organizations. The method usually involves commissioning a third-party organization, typically an executive search firm but possibly a standalone consultant, to research the availability of suitable candidates working for competitors or related businesses. Having identified possible recruits that match the client's requirements, the executive search firm may act as an intermediary to investigate whether the individual might be interested in moving to a new employer and also carry out initial screening of the candidate, negotiations on remuneration, and the employment contract.
