When an organization finds that it needs to hire additional staff, it starts a recruitment process. Recruitment is aimed at developing a pool of possible candidates who are qualified for the job. Once the organization has the list of the qualified people then it must engage in selection to pick out the most qualified. The actual selection is usually completed through interview.
In the interview the candidate meets face to face with the members of the organizations who have been charged with the recruitment.
Care must be taken that the interview is properly conducted because a poorly conducted interview may lead to selection of the "wrong" candidate or they may even discourage and frighten an otherwise qualified person.
