Checking of references: many organizations ask the candidates to provide the name of referees from whom information about the candidates can be solicited. Such information may be related to character, working, etc. the usual referees may be previous employees, person's associated with the educational institutions from where the candidates have received education, or other person's of prominence who may be aware of the candidates behaviour and ability. In our country references are not given adequate importance because of their biasness but these can give very useful information, which may not be available otherwise.
