Employees sharing job postings with their family and friends is a common way to recruit. Why is it problematic to use this approach as the only recruitment method? a. Employees are very likely to recommend people who do not have the skills necessary for the job. b. Employees may only invite people who are similar to themselves, which may lead to illegal discrimination. c. This approach doesn't tend to increase the applicant pool very much. d. Employees tend to describe the job in overly positive terms, which can lead to negative applicant attitudes once they find out what the job is really like
