Pre-employment personality tests can be effective in predicting job performance under certain conditions. These tests should be legal, job-related, and well-validated in order to add objectivity to the recruiting process. They are designed to measure specific traits exhibited by a job applicant and can help identify candidates with a positive demeanor, interpersonal skills, values, and working style that align with the position. The results of these tests are summarised in a report that gives recruiters insights on personality characteristics and behaviors that will contribute to good job performance and the ones that will interfere with it. However, pre-employment personality tests should be used in conjunction with other assessment methods and not solely relied upon to make hiring decisions.
