Olivia Grant chose a sales career for the money, then spent four years dreading every cold call and networking dinner. Her switch to a quieter research role reveals the role of personality in career choices better than any job advert could.
Most people pick careers based on grades, pay, family pressure, or whatever job appears first after graduation.
Personality rarely enters the conversation, even though it influences how much energy a job gives or takes each day.
A good fit can make demanding work feel meaningful, while a poor fit can make even well-paid work exhausting.
Personality is not destiny, and skills, values, and circumstances matter just as much.
Olivia’s long road to a better fit runs through each section that follows.
You will learn how personality traits relate to work, what research reveals, where personality tests fall short, and how to use this knowledge wisely.

Personality at a Glance
Personality describes the fairly stable patterns in how you think, feel, and behave across situations.
It grows from a mix of genes, upbringing, culture, and experience, as described in how personality develops over life.
Psychologists most commonly describe personality using five broad traits rather than fixed types.
The research behind the five major personality traits offers the strongest scientific base for career thinking.
Olivia’s personality showed clear patterns long before she entered sales in Ottawa.
She loved deep conversations with one or two people, careful research, and quiet time to think before deciding anything.
How Personality Influences Career Choices
Energy and social needs
Some people gain energy from constant interaction, while others need to recharge quietly alone.
Olivia left every sales conference completely drained, even when she had performed well and closed new deals.
Preferred pace and structure
Certain people thrive on routine and clear rules, while others prefer variety and freedom. A mismatch here can make a job feel either suffocating or chaotic.
Values and motivation
Personality also affects what people find rewarding, such as helping others, solving puzzles, or earning status.
Work that matches these motivations feels more meaningful and easier to sustain.
Stress tolerance
Some people stay calm under pressure, while others feel stress deeply and need steadier environments.
High-pressure roles can wear down people who are naturally more sensitive to stress.
Decision style
Some people decide quickly on instinct, while others need time, data, and reflection.
Olivia’s careful decision style clashed with the fast, pushy rhythm of monthly sales targets.
The Big Five Traits and Career Fit
Openness to experience
People high in openness tend to enjoy new ideas, creativity, and plenty of variety. They may thrive in research, design, writing, or entrepreneurship, where curiosity is rewarded.
Conscientiousness
Conscientious people tend to be organized, reliable, and goal-driven in nearly any work setting.
This trait supports success in almost every career, from accounting to surgery to project management.
Extraversion
Extraverts gain energy from people and activity, so they may enjoy sales, teaching, events, or leadership roles.
Introverts may prefer roles with deeper concentration and fewer constant interactions, though many lead successfully.
Agreeableness
Agreeable people tend to be warm, cooperative, patient, and caring toward the people around them. They may enjoy nursing, counseling, social work, or customer care, though they may struggle in highly competitive settings.
Emotional stability
People with high emotional stability stay calm under pressure and recover quickly from setbacks. They may handle emergency services, trading, or crisis management more comfortably than others.
| Trait | High scorers may enjoy | Possible challenges |
|---|---|---|
| Openness | Research, design, writing | Repetitive routine work |
| Conscientiousness | Accounting, medicine, management | Rigid perfectionism |
| Extraversion | Sales, teaching, events | Isolated desk roles |
| Agreeableness | Nursing, counseling, care | Highly competitive settings |
| Emotional stability | Emergency work, trading | Rarely a barrier |
Holland’s Six Career Personality Types
Psychologist John Holland proposed that people and work environments can be grouped into six types, called RIASEC.
Most people match a blend of two or three types rather than just one.
Realistic
Realistic types enjoy hands-on work with tools, machines, plants, or animals, and they like seeing results.
Common careers include engineering, construction, farming, and skilled mechanical or electrical trades.
Investigative
Investigative types enjoy analyzing problems, researching questions, and working with complex ideas for long stretches.
Olivia scored highest here, which matched her love of research and careful analysis.
Artistic
Artistic types value creativity, self-expression, and freedom from rigid rules or tight supervision.
They may thrive in design, music, writing, acting, photography, or advertising work.
Social
Social types enjoy helping, teaching, and caring for other people in meaningful ways.
Teaching, nursing, counseling, coaching, and social work tend to suit this type well.
Enterprising
Enterprising types enjoy leading, persuading, competing with rivals, and taking calculated business risks.
Sales, management, law, politics, and entrepreneurship tend to attract this energetic type.
Conventional
Conventional types prefer order, data, and clear procedures in their daily work.
Accounting, administration, banking, insurance, and logistics usually fit this preference very well.
| Type | Core interest | Example careers |
|---|---|---|
| Realistic | Hands-on work | Engineer, electrician, farmer |
| Investigative | Analysis and research | Scientist, analyst, researcher |
| Artistic | Creativity | Designer, writer, musician |
| Social | Helping people | Teacher, nurse, counselor |
| Enterprising | Leading and persuading | Salesperson, manager, lawyer |
| Conventional | Order and data | Accountant, administrator, banker |
From the Eyes of Research
Some personality traits appear to support job performance across nearly every occupation studied so far.
In a meta-analysis by Murray Barrick and Michael Mount, conscientiousness was the only trait linked to performance across all five occupational groups studied.
Extraversion predicted performance mainly for managers and salespeople, whose work centers on social interaction.
Fitting well with a job and an organization also appears to matter for how people feel and behave at work.
A meta-analysis of 172 studies by Amy Kristof-Brown and colleagues linked fit with work attitudes, performance, withdrawal, strain, and tenure.
These relationships held broadly across many different jobs, organizations, situations, and settings.
Popular personality tests are not all equally reliable when people use them for career decisions.
Writing in Fortune about the Myers-Briggs test, Roman Krznaric noted roughly a 50 percent chance of getting a different type after five weeks.
Most of this research comes from Western workplaces, and personality explains only part of career success.
Still, it suggests that traits and fit matter, while some popular tests deserve caution.
The Limits of Personality Tests
Personality tests can start useful conversations, but they should never make career decisions for you.
Results can change with mood, life stage, and how honestly someone answers on a given day.
Type-based tests can also box people into narrow labels that ignore growth and context.
Olivia once avoided research roles because an online quiz labeled her a “people person,” which never felt true.
Science-based measures of the Big Five are generally more reliable than popular type quizzes.
Even so, results work best alongside reflection, feedback, and real experience in actual jobs.
Introverts, Extraverts, and Career Success
Introverts can thrive in almost any career, including sales and leadership, when the role allows recovery time.
Many build quiet strengths like deep listening, careful planning, and steady attention to detail.
Olivia learned more about the quieter introvert temperament and stopped seeing her need for solitude as a flaw.
Instead, she began looking for work that respected it rather than punished it.
Extraverts may struggle in isolated roles with little contact, but they can add social elements to their week.
Volunteering, mentoring, or team projects can balance quieter jobs for people who crave interaction.
When Your Job and Personality Clash
Not everyone can change careers quickly, because bills, family duties, and local job markets limit options. A poor fit can still be eased while you plan a longer-term move.
Small changes, such as swapping tasks with colleagues or adjusting your schedule, can reduce daily strain.
Simple ideas for learning to enjoy daily work can also make a difficult season more bearable.
Before leaving sales, Olivia asked to handle client research and written proposals for her team.
Those tasks gave her energy back while she prepared for a bigger change.
How to Use Personality in Career Decisions
Reflect on energy, not just ability
Ask which tasks energize you and which drain you, even if you perform both well. Olivia was good at sales, yet it emptied her, while research filled her with energy.
Combine personality with strengths and values
Personality is one piece of a larger puzzle that includes skills, values, and interests.
Methods for spotting your natural strengths add another valuable layer of insight to the picture.
Test careers before committing
Shadow professionals, take short courses, volunteer, or try side projects before making big changes.
Olivia spent three months helping a research team part-time before leaving sales completely.
That season felt uncertain, yet a healthy season of searching is a normal part of finding the right path.
Make decisions carefully
Write down pros, cons, and risks, then talk with people already working in the field. Sound habits for better career decision making reduce costly mistakes and regret.
Build a professional identity that fits
Your career should feel like an honest expression of who you are and who you want to become. Building a professional identity that fits makes work feel less like a costume.
Conclusion
Olivia spent four years dreading cold calls before admitting that her personality and her job were pulling in opposite directions.
Today she works as a user researcher, and she says her energy at the end of the day finally matches her effort.
The role of personality in career choices is real, though it works best alongside skills, values, and honest experimentation.
Research supports the value of traits and fit, while popular online quizzes deserve caution.
This week, list your three most energizing and three most draining work tasks, and look for the pattern.

I’ve actually have been digging deep into this area recently and I would say that INTJ are on point, INFP maybe but don’t know if I would say diplomat – the job options is on point and the ESFP a little, but I also read they are excellent emergency medical personnel.
Yes you are right. Most of the personality types are flexible and overlap with each other. There is no strong boundary between them, however, they are distinct enough to be termed different. Thank you for your thought Rose.
I made such a test about personality type, and the result was INFJ. It seems to me most of the things are true about personality types as many of the traits are corresponding correctly. Thanks for sharing this post. I agree that the jobs we choose might depend on our personality.
Yes! Personality types are real, though there is always overlaps here and there. Thanks for finding the post useful Nelly.
I remember nearing the end of my time in college and trying to figure out what I wanted to do when I grew up. It’s so daunting and all the personality tests and recommended careers were so overwhelming. I do think people tend to gravitate towards something that inevitably matches their personality. I hate thinking of people who feel “stuck” in a career that they’re not a good fit for. As you pointed out, it can be detrimental to your mental health. Great post, thank you.
Exactly, personality plays a big role in job successes. That explains why another excels where another fails. Though there are other factors, but personality is in the frontline.
Thank you Gloria for finding this post worthy.
what gets to me the most in the working field is the demands bosses make, you give 110% and it`s still not enough.
Thanks for share your opinions
Thank you Roseline for your thought. That is why it’s good to liberate oneself from the rat race of employment. Being under a boss seldom be a good experience. While it is good to start life learning from bosses, it’s better to have that experience and proceed to independence.
Thanks for your thought once again Roseline.
You are right Nisee and Nisee, thank you for stopping by.
