The candidate who interviewed perfectly and quit in four months
They said all the right things. They had the right energy. The hiring manager loved them. You had a flicker of doubt you could not justify, so you let it go. Four months later they resigned and the postmortem turned up nothing useful because every tool you used said they were a good fit.
The tools were not wrong. They were just not measuring enough.
Five traits is a blurry photo
Most personality assessments report five broad scores: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism. That is the equivalent of describing a photograph by its five dominant colors. You get something, but you lose the composition, the texture, the thing that actually makes it a specific image of a specific person.
A candidate who scores 50th percentile on Agreeableness could have high Trust paired with low Cooperation. Or low Trust paired with high Cooperation. Those are completely different people in a team setting: one believes the best of colleagues but pushes back hard on process; the other assumes the worst but goes along to keep peace. A five-trait test reports them as identical.
The 30-facet OCEAN personality test breaks each domain into six subfacets. Same validated science, six times the resolution.
What 30 facets actually looks like
Two real profiles. Same broad Conscientiousness score. Completely different people:
"Their Conscientiousness at 94 is extraordinary: Deliberateness at 100, Self-Discipline at 90, Orderliness at 90. For a compliance-heavy operations role, this is the profile you want. For a fast-moving startup where priorities shift daily, it might mean they cannot adapt."
"High intellectual curiosity at 90 paired with low excitement-seeking at 10. This person does not chase novelty through experiences or thrills; the stimulation is cognitive. They want hard problems, not a ping-pong table."

The employee who is fully compliant and already leaving
You have someone right now who hits every metric, shows up on time, completes every required training, and is updating their resume tonight. You can feel it. But there is nothing in your system that captures it because your system measures behavior, not wiring.
High Self-Discipline (C5) with low Achievement-Striving (C4) means they will do whatever is asked of them and never once push for more. They look like a model employee right up until they leave, because the thing that was missing (internal drive, ambition, a sense of building toward something) was never measured. The broad Conscientiousness score looked fine. The facets told the real story.
Same job, one person exhausted by it, the other restless
Two People leads with nearly identical job descriptions. One absorbs the entire floor's stress through her skin and runs hot all day. The other walks through the same environment and barely registers it. Same role, same title, same 360 feedback score. One will burn out in eighteen months. The other will get bored.
The difference is three facets: Sympathy (A6), Vulnerability (N6), and Activity Level (E4). None of them show up on a broad five-trait report. All three are measured here.

How it works
Send your candidate the test link. They complete 120 questions in about 15 minutes on any device and get their basic five-domain profile immediately. They share their results link with you. From there you can unlock the full 30-facet extended profile, or run a hiring or team dynamics report that unlocks the profile automatically.
Frequently asked questions
What is the difference between 5 traits and 30 facets?
Most personality tests report five broad domains. Each domain is composed of six subfacets. A candidate who scores 50% on Agreeableness could have high Trust and low Cooperation, or the reverse. Those are completely different people in a team, but a 5-trait test reports them as identical. The 30-facet test separates them.
Is using a personality test for hiring legal?
Yes. The Big Five framework complies with EEOC guidelines and has been validated across demographic groups with no adverse impact on protected classes. It should be used as one component of a comprehensive hiring process alongside interviews, work samples, and references.
How long does it take?
About 15 minutes. 120 questions, works on any device. Candidates can receive their own personality report, which improves their experience of your hiring process.
How is this different from MBTI or DiSC?
MBTI has no predictive validity for job performance in peer-reviewed research. DiSC measures four behavioral styles without the resolution to distinguish between two people who present similarly but are wired differently. The Big Five is the only personality framework with decades of meta-analytic evidence linking specific traits to job outcomes. Full comparison here.
