The Rise of Pre-Employment Personality Testing
Pre-employment personality assessments are increasingly standard in corporate hiring. A 2019 survey found nearly 30% of US employers using personality tests, with rates significantly higher among large employers and in competitive fields. For candidates, encountering a personality assessment in the hiring process is now nearly inevitable — understanding how to approach it is essential career knowledge.
What Hiring Personality Tests Actually Measure
Professional hiring assessments are not generic personality tests — they are typically role-benchmarked, measuring specific trait combinations associated with high performance in the target role. Common frameworks:
- Big Five-based tests (SHL OPQ, Hogan, 16PF): Measure broad personality dimensions with established validity for predicting job performance. Most common in large-company hiring.
- DISC-based assessments: Measure behavioral style and communication preferences. Common in sales, customer service, and management hiring.
- Situational Judgment Tests (SJTs): Present work scenarios and ask how you would respond. Implicitly assess personality-relevant behaviors without direct self-report.
The Strategic Case for Honesty
The temptation to give socially desirable answers is understandable. The problem: professional assessments include validity scales — groups of items specifically designed to detect inconsistent or inflated responses. If you claim to "always" be organized while other responses suggest impulsive behavior, validity flags are raised. Additionally, if you successfully present an inflated personality profile and are hired, you have created a guaranteed mismatch between your actual traits and the role's demands — setting up eventual performance and satisfaction problems.
The honest approach: answer based on your typical behavior across typical work situations. Not your best day, not your worst. Your normal pattern.
How to Prepare Authentically
Step 1: Know your actual profile. Take the Big Five test and DISC assessment before any hiring process. Understanding your genuine profile helps you answer consistently and confidently.
Step 2: Understand the role requirements. Research the personality characteristics typically associated with high performance in this type of role. A sales role requires different traits than an engineering role. If your authentic profile aligns well, that is good news worth knowing. If it does not, that is equally important information.
Step 3: Answer based on typical behavior. When asked "I enjoy meeting new people," answer based on your actual typical response — not what you think the role needs. Consistent self-representation across dozens of items is more reliable than item-level manipulation.
Step 4: Use results for your own fit assessment. If a company provides feedback from personality assessments (some do), treat it as information about fit — from your perspective as well as theirs.
