There are at least two important goals of employee selection.
First, human resources departments are trying to select employees who will be good at their jobs. The departments and others involved in the selection process must clearly understand the attributes and skills that will allow the employee to succeed at the job in question. They must then be sure to conduct their selection based on those attributes and skills.
Second, the department wants to select employees who will be likely to stay with the firm and be happy. They want to avoid having constant turnover, particularly at important positions. Therefore, they need to try to determine which potential employees would be likely to stay with the firm for the long term.
