Personality at Work Series: DISC • Holland Codes • 16 Personalities
Two finalists are being considered for the same management role.
Both have the required experience.
Both performed well in their interviews.
Their personality assessments show some meaningful differences.
One candidate scores high in Dominance and Enterprising interests. The other shows stronger Steadiness, Conventional interests, and an Introverted preference.
It would be easy for a hiring team to turn those differences into conclusions.
The first candidate looks like the leader.
The second looks more suited to support work.
That is exactly where personality assessments can become dangerous.
Neither assessment tells you which candidate is more capable of leading the department.
It tells you something about how each candidate may prefer to approach work.
Used responsibly, that information can help a hiring team ask better questions, understand potential strengths and challenges, and compare candidates against the actual requirements of the role.
Used carelessly, the same information can become another source of bias.
The difference comes down to how the assessment is used.
Start With the Job, Not the Personality
Before looking at assessment results, define what successful performance actually requires.
Suppose you are hiring a production supervisor.
The role may require someone who can:
- Coordinate the work of 25 employees
- Respond quickly when production problems occur
- Maintain safety and quality standards
- Coach less-experienced employees
- Resolve disagreements between departments
- Track production performance
- Communicate with management
- Make decisions under pressure
Those are job requirements.
“High D” is not a job requirement.
“Extravert” is not a job requirement.
“ESTJ” is not a job requirement.
“Enterprising” is not a job requirement.
Personality information becomes useful after the organization understands the work.
Then the hiring team can ask:
How might this candidate’s natural work style support these requirements?
and:
Where might this candidate need to adapt?
That keeps the assessment connected to the job.
In the United States, this connection also matters from an employment-practices standpoint. The U.S. Equal Employment Opportunity Commission notes that employment tests and selection procedures should be appropriately related to the job and the purpose for which they are being used. Employers should also understand whether selection procedures create adverse impact for protected groups.
For additional guidance, see the EEOC’s guidance on employment tests and selection procedures.
What Personality Assessments Can Tell You
Personality assessments can provide useful information about tendencies.
Depending on the framework, they may help a hiring team understand things such as:
- Preferred pace
- Communication style
- Comfort with structure
- Decision-making tendencies
- Occupational interests
- Attention to detail
- Preference for collaboration or independent work
- Response to change
- Natural sources of motivation
These insights can add context to the rest of the hiring process.
Suppose a candidate for a field service manager role shows strong Realistic interests.
That may suggest a genuine attraction to practical, technical, hands-on environments.
If the same person also shows High D behavioral tendencies, they may be comfortable making decisions and taking ownership.
An Introverted preference might suggest that they process information more internally before responding.
None of those results tells you whether the person can manage technicians, meet service targets, handle difficult customers, or understand the equipment.
Those questions still need evidence.
What Personality Assessments Cannot Tell You
A personality result does not tell you whether someone is intelligent.
It does not tell you whether someone has integrity.
It does not prove that someone will perform well.
It does not determine leadership ability.
It does not establish technical competence.
It does not tell you whether someone will get along with a particular manager.
And it should not become a pass-or-fail test based on someone’s personality label.
An Introvert can be an excellent salesperson.
A High S employee can make difficult decisions.
A High D candidate can be patient and collaborative.
A Conventional type can be innovative.
An Artistic type can work accurately within strict requirements.
People develop skills.
They adapt to circumstances.
They behave differently depending on experience, responsibility, motivation, and context.
That is why personality should remain one source of information rather than becoming the hiring decision.
The Problem With the “Ideal Personality”
Many hiring mistakes begin with a seemingly reasonable idea:
What personality type would be perfect for this job?
The hiring team then starts building a personality template.
Salespeople should be High I.
Managers should be High D.
Accountants should be High C.
Engineers should be Introverted Thinkers.
Customer service employees should be Social types.
This feels structured.
It can also become stereotyping with numbers attached.
Jobs are usually more complicated than the stereotype.
Consider outside sales.
The role certainly may reward confidence, relationship building, persistence, and comfort with interaction.
But one successful salesperson may win business through visible energy and persuasion.
Another may succeed by listening carefully, understanding the customer’s technical problem, and building credibility over time.
The performance requirement is selling effectively.
There can be more than one personality path to that result.
Use Assessments to Explore Fit, Not Define Eligibility
A better approach is to distinguish between qualification and work-style fit.
Qualification answers questions such as:
- Does the candidate have the required experience?
- Can they perform the technical work?
- Do they hold the necessary licenses or certifications?
- Can they demonstrate the competencies required by the role?
Personality adds another layer:
- What parts of the role may feel natural?
- What aspects may require more conscious adaptation?
- What work environment may help this person perform?
- What potential strengths deserve further exploration?
- What challenges should the interview team investigate?
That distinction is important.
A candidate should not be rejected simply because their personality does not resemble the hiring manager’s mental picture of the role.
DISC in Hiring: Look at Behavior Without Turning It Into a Scorecard
DISC can help describe behavioral tendencies such as directness, pace, interaction, patience, and attention to detail.
Each style can contribute differently.
High D Candidates
A candidate with strong Dominant tendencies may appear:
- Direct
- Decisive
- Comfortable taking ownership
- Results-focused
- Willing to challenge obstacles
Those tendencies may be useful in a role requiring rapid decisions or visible accountability.
They can also prompt useful interview questions:
Tell me about a situation where moving quickly would have created unnecessary risk. How did you know when to slow down?
The purpose is not to prove that High D is good or bad.
It is to investigate how the candidate manages a likely tendency.
High I Candidates
A candidate with strong Influential tendencies may appear expressive, persuasive, socially confident, and enthusiastic.
Instead of concluding that the candidate will automatically excel in a people-facing role, explore how those tendencies translate into performance.
For example:
Tell me about a time when you had to gain support from someone who was initially skeptical of your idea.
You are looking for evidence of influence, not simply sociability.
High S Candidates
Candidates with strong Steady tendencies may value cooperation, consistency, and supportive relationships.
That might help in roles requiring patience, continuity, or team coordination.
A hiring team could ask:
Tell me about a time when you had to make an unpopular decision that affected people you worked closely with.
That gives the candidate an opportunity to demonstrate how they handle a situation that may require behavior outside their natural preference.
High C Candidates
Candidates with strong Compliant tendencies may pay close attention to accuracy, standards, and evidence.
Those tendencies can be valuable in technical, quality, regulatory, or analytical work.
A useful question might be:
Tell me about a situation where you had incomplete information but still had to make a decision.
Again, the goal is not to penalize carefulness.
It is to understand how the candidate adapts when the situation requires something different.
Holland Codes in Hiring: Understand What Kind of Work Attracts the Candidate
Holland Codes are particularly useful because they focus on occupational interests.
They can help explain what kinds of work naturally capture someone’s attention.
A Realistic candidate may enjoy practical problems, equipment, field work, or tangible outcomes.
An Investigative candidate may be drawn to analysis, diagnosis, research, or complex questions.
An Artistic candidate may enjoy design, originality, interpretation, and open-ended problem solving.
A Social candidate may be attracted to teaching, coaching, service, or collaboration.
An Enterprising candidate may enjoy persuasion, leadership, negotiation, and visible goals.
A Conventional candidate may appreciate structure, records, organization, and repeatable systems.
These interests can be meaningful when evaluating role alignment.
But interest is still not ability.
A person may enjoy analytical work without being qualified to perform advanced engineering analysis.
Someone may enjoy leadership without yet having the judgment required to lead a department.
An employee may have relatively low Social interests and still be an excellent manager.
Holland information helps answer:
What kinds of work is this person likely to find engaging?
It does not answer:
Can this person do the job?
16 Personality Preferences in Hiring
The 16 Personality Types framework can add context around how candidates prefer to process information, make decisions, interact, and organize their work.
Extraversion and Introversion
One of the most common hiring stereotypes is assuming that Extraverts are better communicators.
Communication skill and Extraversion are different things.
An Extraverted candidate may respond quickly and think through ideas aloud.
An Introverted candidate may prefer to process the question before answering.
If an interviewer rewards fast verbal response, they may unintentionally favor one style.
For a role requiring presentations, the relevant question is whether the candidate can present effectively.
For a role requiring customer communication, evaluate customer communication.
Do not substitute personality preference for evidence.
Sensing and Intuition
Sensing-oriented candidates may naturally focus on concrete information and practical experience.
Intuitive candidates may pay more attention to patterns, possibilities, and future implications.
Both can be valuable.
A maintenance manager may need practical attention to current equipment problems and the ability to recognize when repeated failures point to a larger systemic problem.
The work determines what matters.
Thinking and Feeling
Thinking preferences may influence attention to logic, consistency, and objective criteria.
Feeling preferences may increase attention to human impact, relationships, and values.
Neither preference determines whether someone can make sound decisions.
Hiring teams should evaluate decision quality directly.
Judging and Perceiving
Judging-oriented candidates may prefer defined plans, deadlines, and closure.
Perceiving-oriented candidates may be more comfortable keeping options open and adapting as conditions change.
Most jobs require some degree of both.
A project manager needs planning.
That same project manager also needs to respond when the plan stops matching reality.
Do Not Use Personality to Replace the Interview
A personality report can create an illusion of certainty.
The candidate suddenly seems understandable.
That can tempt interviewers to stop investigating.
If the assessment says someone is highly analytical, the hiring team may assume the person is good at analysis.
If the report suggests leadership tendencies, they may assume leadership ability.
If the candidate appears highly organized, the team may stop asking for evidence of follow-through.
That is backwards.
Assessment findings should create questions that the interview can test.
They should not answer questions the hiring process has not investigated.
Keep the Core Interview Structured
A strong hiring process evaluates candidates consistently.
That means candidates for the same role should be assessed against the same important job requirements and, where practical, asked the same core structured interview questions.
This creates a more useful comparison.
Suppose the role requires conflict management.
Every finalist might be asked:
Tell us about a situation where two people you depended on strongly disagreed. What did you do?
The hiring team can score each response against the same criteria.
Assessment results can add context afterward.
Perhaps one candidate’s DISC profile suggests a naturally direct style.
Another appears more harmony-oriented.
Now the hiring team can compare the evidence from the interview with the tendencies suggested by the assessment.
That is more informative than assuming how either person would behave.
For more on this process, see Structured Interviews: A Smarter Way to Evaluate Candidates.
Look for Evidence That Confirms or Challenges the Assessment
Personality results are most useful when they become part of a larger evidence set.
Imagine a candidate whose results suggest strong High D tendencies.
The interview shows that the candidate consistently seeks input before making consequential decisions.
That is useful information.
Perhaps experience has taught the person when to slow down.
Another candidate may appear highly cooperative on an assessment but describe several situations where they addressed poor performance directly.
Again, useful.
People are more complex than their assessment profile.
The hiring process should be interested in those complexities.
Be Careful With “Culture Fit”
Personality assessments sometimes get pulled into discussions of culture fit.
That phrase can become problematic when it really means:
Would this person act like the people already here?
A team of fast, forceful people may interpret another High D candidate as a natural fit.
A quieter, more deliberative candidate may feel different.
Different may be exactly what the team needs.
A better question is whether the candidate can work effectively within the organization’s legitimate expectations and contribute to the work.
Consider what the team currently lacks as well as what already feels familiar.
Hiring only people who resemble successful incumbents can gradually narrow the range of perspectives available to the organization.
Avoid the “Mini-Me” Hiring Problem
Managers naturally respond positively to candidates who remind them of themselves.
They may communicate similarly.
They may solve problems the same way.
Conversation feels easier.
Personality information can accidentally reinforce this bias.
A High D manager may see another High D candidate as strong and decisive.
The same manager may view a High S candidate as lacking urgency.
A highly analytical manager may respect another detail-oriented candidate while interpreting a more relational style as less rigorous.
Those are interpretations.
The job requirements should decide which behaviors matter.
A disciplined process forces the manager to explain:
What evidence shows that this trait matters for successful performance in this role?
That is much harder than saying:
This person just feels like a better fit.
Compare Candidates Against the Role, Not Against Each Other
Candidate comparison becomes more useful when the job remains the reference point.
Suppose two finalists are being considered for a regional sales leadership role.
Candidate A is highly outgoing, competitive, and comfortable driving fast decisions.
Candidate B is more measured, structured, and relationship-focused.
The question should not be:
Which personality is better?
It should be:
What does this specific role require, and what evidence do we have that each candidate can meet those requirements?
Perhaps the team needs aggressive market expansion.
Perhaps it needs operational discipline after a period of uncontrolled growth.
Perhaps both capabilities matter.
Once the work is clear, the differences between the candidates become more meaningful.
This is also the principle behind structured candidate comparison: compare each finalist against defined role criteria so strengths, challenges, and tradeoffs become visible.
Personality Should Be One Input Among Several
Strong hiring decisions combine different kinds of evidence.
The resume tells you about experience.
Technical evaluation can show whether the candidate has required skills.
Structured interviews provide examples of past behavior and judgment.
References may provide additional context.
Personality assessments can help explain work-style tendencies and interests.
No single source should carry the entire decision.
When several independent sources point in the same direction, confidence increases.
When they conflict, the hiring team has something worth investigating.
That is one of the most valuable roles an assessment can play.
It can reveal questions.
What About Benchmarking?
Some organizations compare candidates with successful employees or role benchmarks.
This can be useful when the benchmark is based on meaningful job requirements and interpreted carefully.
It becomes risky when the organization assumes:
Our best employee looks like this, so the next hire should look the same.
The strongest current employee may succeed because of experience, relationships, unusual expertise, or strengths that compensate for other weaknesses.
Copying one person’s personality profile can turn a successful employee into a stereotype of the role.
A benchmark should help identify patterns worth examining.
It should not become a personality clone machine.
Do Not Hide Behind the Assessment
Hiring managers sometimes treat assessment results as objective because they produce numbers.
Numbers can still be misused.
A score does not become a valid hiring requirement merely because software generated it.
Someone still has to decide:
- Why the measure matters
- How it relates to the role
- How much weight it should receive
- What other evidence will be considered
- How conflicting information will be handled
That human judgment needs to remain visible.
If a hiring team cannot explain why an assessment result matters to job performance, it probably should not carry significant weight in the decision.
Watch for Adverse Impact and Accessibility
Responsible assessment use also requires attention to how selection practices affect different groups of applicants.
A procedure that appears neutral can still create concerns if it disproportionately excludes protected groups and cannot be appropriately justified.
The EEOC’s Uniform Guidelines on Employee Selection Procedures address adverse impact and methods employers can use when evaluating selection practices.
Disability considerations matter as well. Employment tests and other selection criteria may also be subject to requirements under the Americans with Disabilities Act, including issues involving job relatedness, business necessity, and reasonable accommodation.
Employers can review additional information from the EEOC’s employment testing guidance and the Americans with Disabilities Act.
For specific legal or compliance questions, employers should work with qualified employment counsel rather than relying on an assessment vendor or a blog article.
A Practical Process for Using Personality Assessments Responsibly
1. Define the Role
Identify the actual responsibilities, outcomes, skills, working conditions, and behaviors required for success.
Start there.
2. Decide What the Assessment Is Intended to Add
Be specific.
Are you trying to better understand communication tendencies?
Occupational interests?
Preferred pace?
Approach to structure?
Do not use an assessment simply because it is available.
3. Keep Basic Qualifications Separate
Verify experience, certifications, technical skills, and other genuine requirements independently.
Personality should not substitute for qualification.
4. Use Assessment Results to Create Questions
Turn tendencies into areas for investigation.
If a candidate appears highly independent, ask for examples of effective collaboration.
If they appear conflict-avoidant, ask about a difficult disagreement.
If they appear highly detail-focused, ask about situations requiring rapid decisions.
5. Evaluate Every Candidate Against the Same Core Criteria
Candidates should face the same important standards.
This makes comparison clearer and reduces the opportunity for personality labels to distort expectations.
6. Compare Evidence
Look at the resume, assessment, structured interview, skills evidence, and other relevant inputs together.
Do they reinforce one another?
Do they conflict?
Where do you need more information?
7. Discuss Strengths and Challenges
Avoid trying to label someone a “fit” or “misfit.”
Identify potential strengths.
Identify possible challenges.
Ask whether those challenges matter for this particular job.
8. Document the Reason for the Decision
The hiring team should be able to explain why the selected candidate was chosen using job-related evidence.
“She was an ENFJ” is not a useful hiring rationale.
“She demonstrated the technical experience, coaching capability, judgment under pressure, and cross-functional communication required by the role” is.
Personality may help explain how she is likely to approach those responsibilities.
It should not replace the evidence that she can perform them.
Example: Hiring a Maintenance Supervisor
Consider a plant hiring a maintenance supervisor.
The role requires technical credibility, work prioritization, coaching, coordination with production, safety awareness, and decision-making during equipment failures.
Candidate A shows strong Dominant and Realistic tendencies.
The hiring team might initially think:
Perfect. Decisive and hands-on.
But the interview still needs to establish whether the candidate can develop technicians, cooperate with production, and maintain safety discipline when pressure is high.
Candidate B shows stronger Steady and Investigative tendencies.
The team might worry that the candidate will move too slowly.
The structured interview may reveal that the candidate has managed dozens of emergency shutdowns and can make fast decisions when the situation requires it.
The assessment still provides useful information.
Candidate A may need to consciously slow down and gather input in some situations.
Candidate B may prefer more analysis when time permits.
Neither tendency tells the team who should be hired.
The evidence does.
Example: Hiring a Sales Manager
A company is filling a sales management role.
One candidate has High I and Enterprising tendencies.
They are engaging, confident, and persuasive.
Another candidate is more High C, Conventional, and Introverted.
If the organization equates sales leadership with charisma, the first candidate may appear to be the obvious choice.
But suppose the department’s primary problem is not motivation.
It is forecast accuracy, inconsistent pipeline management, poor coaching discipline, and weak follow-through.
Now the role looks different.
The second candidate’s strengths may deserve much more attention.
Or the first candidate may have already demonstrated exceptional operational discipline despite their personality tendencies.
The assessment cannot settle the question.
It helps the team see the tradeoffs.
Example: Hiring an Engineer
An engineering team may assume that an Investigative or Thinking-oriented candidate is naturally a better fit.
Those preferences certainly may align with some aspects of engineering work.
But the role may also require communicating with customers, managing field technicians, coordinating production changes, or leading projects across departments.
A candidate’s technical competence needs direct evidence.
Their assessment can then help the organization anticipate how they may approach the broader work around that technical expertise.
Structured Hiring Reduces the Temptation to Stereotype
Stereotyping thrives in vague hiring processes.
When nobody has clearly defined the job requirements, interviewers rely more heavily on impressions.
When questions differ dramatically between candidates, comparisons become difficult.
When there is no scoring framework, the most memorable candidate can feel like the strongest candidate.
When personality results are added to that environment, they can become another source of intuition.
Structure helps.
Define the role.
Use consistent criteria.
Conduct structured interviews.
Gather multiple forms of evidence.
Compare finalists side by side.
Then use personality insights to add context to the decision.
This makes the assessment more useful precisely because it carries less responsibility for determining the outcome.
Personality Can Be Even More Valuable After the Hire
There is another reason to avoid treating assessment results as a screening mechanism.
The same information can become extremely useful after someone joins the organization.
A manager can use personality insights to think about:
- Communication
- Feedback
- Onboarding
- Delegation
- Team interaction
- Motivation
- Conflict
- Development
The assessment becomes part of understanding how to help a capable employee succeed.
That is a much broader use than simply deciding whether someone gets through the hiring gate.
Using Multiple Frameworks Can Reduce Oversimplification
One advantage of looking through several personality frameworks is that the candidate becomes harder to reduce to a single label.
A candidate may be:
- High D in DISC
- Investigative and Realistic in Holland
- Introverted and Thinking in 16 Personalities
Calling that person simply “a High D” misses much of the picture.
Their Dominant behavior may show up alongside a strong interest in analysis and practical technical work.
Their Introversion may influence how they process information.
Another High D candidate could have a completely different pattern.
Talent Insights combines DISC, Holland Codes, and 16 Personality types for this reason: each framework describes a different part of how someone approaches work.
The broader picture can help reduce the temptation to make a hiring decision from one personality label.
Learn more in the Personality Types Explained series and Why Personality Assessments Are More Useful Together Than Alone.
The Hiring Team Still Owns the Decision
An assessment should support professional judgment.
It should not become the authority that makes the decision.
The hiring team still has to determine:
- What the job requires
- Which evidence matters
- How much weight each input deserves
- What tradeoffs are acceptable
- Which candidate has demonstrated the strongest overall alignment
That responsibility cannot be outsourced to a personality profile.
Final Thoughts
Personality assessments can make hiring more thoughtful.
They can expose differences between strong candidates that might otherwise be difficult to articulate.
They can help interviewers ask better questions.
They can reveal potential strengths and challenges worth exploring.
They can provide useful context when several candidates all look qualified on paper.
But their value depends on discipline.
Start with the job.
Evaluate real qualifications and competencies.
Use consistent interview criteria.
Treat personality as evidence about tendencies rather than proof of capability.
Compare candidates against the work they will actually be responsible for doing.
That approach gives hiring teams the benefit of personality insight without reducing people to personality types.
And that is where assessments become most useful: helping people make better decisions about complex candidates rather than making the decision for them.

Frequently Asked Questions
Should personality assessments be used in hiring?
They can be one useful part of a broader hiring process when they are relevant to the role and interpreted appropriately. Assessment results should be considered alongside qualifications, experience, structured interviews, skills evidence, and other job-related information.
Can an employer reject a candidate because of a personality assessment?
Employers should be cautious about using personality results as automatic pass-or-fail criteria. Selection procedures should be connected to legitimate job requirements, and employers should consider applicable employment laws and potential adverse impact. Organizations should consult qualified employment counsel about their specific use of assessments.
What is the biggest risk of using personality assessments in hiring?
One major risk is turning tendencies into stereotypes. A hiring team may assume that an Introvert cannot sell, a High S candidate cannot lead, or a High D candidate will automatically make a strong manager. Those conclusions go beyond what personality results can establish.
Should employers create an ideal personality profile for each job?
Employers should begin with job requirements rather than trying to create a perfect personality type. Different people can succeed in the same role through different strengths and working styles.
How should DISC be used in hiring?
DISC can provide context about behavioral tendencies such as pace, directness, interaction, patience, and attention to detail. Those insights can help hiring teams identify areas to explore during interviews rather than serving as proof that someone can or cannot perform a job.
How can Holland Codes help in hiring?
Holland Codes describe occupational interests. They can help hiring teams understand what kinds of work a candidate may naturally find engaging, but they do not establish skill or competence.
Can Introverts succeed in leadership or customer-facing roles?
Yes. Introversion describes a preference for how someone directs and restores energy. It does not determine leadership ability, communication skill, confidence, or customer effectiveness.
How should personality assessments work with structured interviews?
Use consistent core interview questions and job-related criteria for candidates being evaluated for the same role. Personality results can provide context and suggest areas worth exploring, while the structured interview provides comparable behavioral evidence.
What should be included in a strong candidate comparison?
A strong comparison can include qualifications, relevant experience, skills, structured interview evidence, assessment insights, and the specific requirements of the role. The purpose is to make important strengths, challenges, and tradeoffs visible.
Are personality assessments subject to employment law?
Employment tests and selection procedures can be subject to federal, state, and local employment laws. EEOC guidance addresses issues including job relatedness, adverse impact, disability considerations, and other requirements affecting selection procedures. Employers should seek legal advice about their particular process.
