Review resumes and match each candidate's background to the job requirements. Companies sometimes receive hundreds of resumes for an ad. However, human resources may only consider a half dozen. During bad economic periods, a number of candidates may have an education and experience that exceed the qualifications for the job. Contrarily, it may be tougher to find qualified candidates during good economic times. Nevertheless, human resources and the hiring manager must determine how many candidates they can realistically bring in for an interview.
