Recruitment is the overall process of identifying, sourcing, screening, shortlisting, and interviewing candidates for jobs within an organization. Recruitment also is the process involved in choosing people for unpaid roles. Managers, human resource generalists, and recruitment specialists may be tasked with carrying out recruitment, but in some cases, public-sector employment, commercial recruitment agencies, or specialist search consultancies such as Executive search in the case of more senior roles, are used to undertake parts of the process. Internet-based recruitment is now widespread, including the use of artificial intelligence (AI).
