The Rise of Personality Testing in Hiring
A 2019 survey found that 29% of US employers use personality tests in hiring, up from 15% a decade earlier. In the UK, 75% of FTSE 100 companies use psychometric assessments for graduate hiring. The trend is accelerating as organizations seek objective, structured methods to complement interview-based selection, which research consistently shows has limited predictive validity.
Understanding what personality assessments measure, how they are used, and what employers are actually looking for helps candidates approach these tests more strategically — and more honestly.
What Employers Are Actually Measuring
Professional personality assessments used in hiring are not looking for a single "perfect" personality type. They are typically assessing:
Role fit: Does your personality profile match the behavioral requirements of this specific role? Sales roles require different profiles than analytical roles. Management roles require different profiles than individual contributor roles. Employers develop role benchmarks — descriptions of the personality profile associated with high performance in a role — and compare candidates to those benchmarks.
Culture fit: Does your personality align with the organization's culture? High-growth startups may benchmark for high-Openness and tolerance for ambiguity. Traditional banks may benchmark for high-Conscientiousness and low risk-taking.
Derailers: Some assessments specifically screen for personality patterns associated with leadership derailment — the dark triad traits (narcissism, Machiavellianism, psychopathy), extreme emotional volatility, or interpersonal behaviors that damage team function. These are assessed through dark-side personality inventories like the Hogan Development Survey rather than standard Big Five assessments.
The Major Hiring Assessment Contexts
Graduate/Entry-Level Hiring
At this level, personality assessments are used primarily for culture fit and trainability screening when candidates have minimal work experience. Conscientiousness, intellectual curiosity (Openness), and Emotional Stability are the primary screening dimensions — they predict training success and early career performance in data-scarce candidate pools.
Mid-Level Professional Hiring
Here, assessments focus on role-specific fit. A sales hire will be assessed for Extraversion, achievement motivation, and resilience. A technical hire for analytical depth, detail orientation, and independent work capability. A manager hire for leadership style compatibility, conflict management approach, and team orientation.
Executive and Leadership Selection
The highest-stakes assessment context uses comprehensive instruments like the Hogan suite, combining bright-side strengths, dark-side derailers, and values measurement. Organizations at this level understand that the personality characteristics that enable someone to reach senior leadership (confidence, assertiveness, risk tolerance) can become liabilities (arrogance, recklessness, narcissism) under pressure. Nuanced derailer assessment is the primary value here.
Preparing for Personality Assessments
The best preparation is self-knowledge, not test manipulation. Understand your own Big Five profile before encountering employer assessments. Know your strengths and their shadow sides. Be able to articulate your work style preferences authentically. Take the Big Five test and DISC assessment to understand your profile — not to learn what to say in a hiring test, but to develop the self-awareness that makes honest responses to any personality assessment coherent and confident.
