Using Personality Tests in Hiring: A Practical Guide
Which Frameworks Fit Hiring
DISC: most practical — describes observable workplace behavior. 16 Personalities: adds cognitive processing style. Strengths: identifies natural talents for role placement. Enneagram: better for post-hire team development, not selection.
Legal Considerations
Never use personality tests as the sole hiring basis. No type is inherently better for any job. Tests must comply with EEOC guidelines: job-related, non-discriminatory, consistent with business necessity. Be transparent with candidates.
Best Practices
Define what matters before testing. Choose the right framework for the question. Look for fit patterns, not perfect matches. Use results in interviews, not as filters. Build balanced teams with diverse work styles.
