The sources of external recruitment include advertisements, employment agencies, educational institutions and employment exchanges. These sources are obtained from outside the company.
The external recruitment source, advertisements, covers a huge market area. Radio, television and newspapers are commonly used as mediums. Employment agencies, which could be private or public, match job openings with suitable applicants. They also categorize and screen applicants accordingly. Public employment agencies usually don't ask for any service payment. Education institutions like high schools, vocational and technical schools, colleges and universities usually have their own staff who assist in the recruitment of suitable fresh graduates or high school leavers. The government runs specific employment exchanges, which have become a means of employing people to work in government agencies.
