Referral recruitment programs allow both outsiders and employees to refer candidates for filling job openings. Online, they can be implemented by leveraging social networks.
Mobile recruiting is a recruitment strategy that uses mobile technology to attract, engage, and convert candidates.
Some recruiters work by accepting payments from job seekers, and in return help them to find a job. This is illegal in some countries, such as in the United Kingdom, in which recruiters must not charge candidates for their services (although websites such as LinkedIn may charge for ancillary job-search-related services). Such recruiters often refer to themselves as "personal marketers" and "job application services" rather than as recruiters.
Employers may re-recruit prior rejected candidates or recruit from retired employees as a way to increase the chances for attractive qualified applicants.
In some companies where the recruitment volume is high, it is common to see a multi-tier recruitment model where the different sub-functions are grouped together to achieve efficiency.
