What Personality Assessments Can (and Can't) Tell You
Hiring the right leader requires more than reviewing a resume or conducting a great interview. Organizations are increasingly incorporating personality assessments into their hiring process to gain additional insight into how candidates communicate, solve problems, lead teams, and respond to challenges.
While these tools can be valuable, they can also be misunderstood or overused. Personality assessments should enhance a hiring decision, not make it.
We’ve seen firsthand how assessments can enhance hiring outcomes, like stronger candidate alignment and on-the-job success, when used appropriately, and where they fall short when relied on as standalone predictors.
What Is a Personality Assessment?
A personality assessment is designed to measure behavioral preferences, communication styles, motivations, and workplace tendencies. Unlike technical skills tests or cognitive ability assessments, personality assessments are intended to provide insight into how someone approaches work rather than whetherthey possess the skills to perform it.
Many organizations use assessments during executive search or leadership hiring to better understand:
Leadership style
Decision-making preferences
Communication tendencies
Conflict resolution approach
Adaptability to change
Team collaboration style
Motivators and workplace preferences
The goal isn't to label candidates. It's to create a fuller picture of how someone may fit within a specific organization and leadership team.
What Can Personality Assessments Tell You?
When used correctly, assessments provide valuable context that interviews alone may not uncover.
Communication Style
Understanding whether a candidate prefers direct, collaborative, analytical, or relationship-driven communication can help hiring managers evaluate team compatibility and leadership effectiveness.
Leadership Preferences
Some leaders naturally excel at coaching and developing teams, while others thrive in fast-paced operational environments or strategic planning roles.
Neither style is inherently better—they simply align with different organizational needs.
Workplace Motivators
Assessments can help identify what energizes a candidate, whether that's solving complex problems, building relationships, creating structure, leading change, or achieving measurable results.
This information often supports stronger long-term retention when matched with the right organizational culture.
Potential Development Areas
No executive is perfect.
Assessments frequently reveal opportunities for coaching and leadership development that organizations can proactively address after hiring.
Rather than being viewed as weaknesses, these insights often become valuable onboarding and succession planning tools.
What Can't Personality Assessments Tell You?
This is where many organizations make costly mistakes.
A personality assessment should never be treated as a prediction of future performance.
It cannot accurately measure:
Industry expertise
Technical knowledge
Emotional intelligence in real-world situations
Integrity
Work ethic
Business judgment
Cultural contribution
Ability to navigate organizational politics
Track record of delivering results
A candidate may score perfectly for a desired behavioral profile yet lack the leadership experience necessary for the role.
Likewise, an executive whose assessment differs from an "ideal" profile may become one of the strongest leaders in the organization because of experience, adaptability, and proven execution.
Should Personality Assessments Eliminate Candidates?
In most cases, no.
Using assessments as a pass-or-fail screening tool can unintentionally eliminate highly qualified leaders who think differently but perform exceptionally.
Instead, assessment results should generate better interview questions.
For example:
How does this executive handle conflict?
What environments bring out their best performance?
How have they adapted their leadership style over time?
What types of teams have they built successfully?
The assessment becomes a conversation starter—not the final decision.
Frequently Asked Questions
Are personality assessments accurate for hiring?
Personality assessments can provide valuable behavioral insights, but they should not be used as the sole predictor of job performance. They work best when combined with interviews, experience evaluation, and reference checks.
Should executive candidates complete personality assessments?
Many organizations include assessments as part of executive hiring. They can improve discussions around leadership style, communication, and team fit when interpreted by experienced professionals.
Do personality assessments predict leadership success?
No. Leadership success depends on many factors, including experience, decision-making, emotional intelligence, organizational culture, and business strategy. Assessments offer additional context—not certainty.
What is the biggest mistake companies make with personality testing?
Treating assessment results as a hiring decision instead of one component within a comprehensive executive evaluation process.
The Bottom Line
Hiring great leaders isn't about finding someone with the "perfect" personality profile.
It's about identifying candidates whose experience, leadership capabilities, business judgment, and behavioral style align with the organization's goals.
Personality assessments can add meaningful insight, but they should never replace thoughtful interviews, proven experience, or professional executive search expertise.
The best hiring decisions come from evaluating the whole leader—not just the assessment report.
Let's Talk About Assessments
Whether you're considering adding personality assessments to your hiring process or reevaluating how you're using them today, it's important to understand both their value and their limitations.
When interpreted correctly and paired with thoughtful interviews, experience, and business context, assessments can become a useful tool for making more informed hiring decisions. But they work best as one piece of a comprehensive evaluation, not the entire picture.
