During my last job application, I completed what the company described as a “work style questionnaire.” It took about 25 minutes. The instructions said there were no right or wrong answers and that I should respond honestly based on my natural preferences. It felt like a personality quiz—the kind of thing you might find in a magazine. I thought nothing of it until a colleague in HR told me, months later, that the questionnaire had generated a detailed personality profile that was used alongside my interview to determine whether I was a good cultural fit.
Nobody told me that during the application. Nobody told me what traits were being measured. And nobody told me the test was made by one of the largest psychometric companies on the planet.
What the SHL OPQ Actually Is
The Occupational Personality Questionnaire is developed by SHL, a global talent assessment company whose tests are used by over 10,000 organisations worldwide, including the majority of FTSE 100 companies and a significant portion of the Fortune 500. The OPQ measures 32 personality characteristics grouped into three domains: relationships with people, thinking style, and feelings and emotions. It is not a clinical test like the MMPI. It is a workplace behaviour assessment designed to predict how someone will perform in a professional setting.
The standard version—the OPQ32r—presents 104 blocks of statements. Each block contains three or four statements, and you are asked to select which statement is most like you and which is least like you. This forced-choice format is specifically designed to prevent candidates from gaming the test by selecting only socially desirable answers. You cannot simply agree with everything positive. You must make trade-offs, and those trade-offs reveal your genuine behavioural preferences.
Why Most Candidates Do Not Know They Are Being Profiled
Here is the part that unsettles people. Many employers do not explicitly tell candidates that the “work style questionnaire” or “behavioural assessment” they are completing is a validated psychometric instrument that generates a detailed personality profile. The language in the invitation email is deliberately neutral. Candidates assume it is a minor step in the process. In reality, the OPQ profile is often reviewed before the interview even takes place—and in some cases, it determines whether an interview is offered at all.
The forced-choice format makes the OPQ difficult to prepare for through memorisation, but understanding how the test is structured and what dimensions it measures gives candidates a significant advantage. Spending time with an SHL OPQ practice test helps you understand the forced-choice mechanism, recognise which personality dimensions map to common job competencies, and approach the real assessment with realistic expectations rather than blind confusion.
What the 32 Scales Actually Measure
The OPQ’s 32 scales cover everything from “persuasive” and “controlling” to “data rational” and “emotionally controlled.” It measures how outgoing you are, how you handle conflict, whether you prefer structured or flexible environments, how you process information, and how you respond to pressure. The profile is then matched against a competency framework specific to the role you are applying for. A candidate for a sales position will be evaluated differently from a candidate for a compliance role, even though both take the same test.
This is what makes the OPQ powerful—and what makes it feel invasive to candidates who were not expecting it. The test does not label you as good or bad. It maps your natural tendencies against the behavioural requirements of the specific job. If you score high on “independent-minded” but the role requires close teamwork and consensus-building, the mismatch will appear in your profile—even if your CV and interview were flawless.
The Test You Already Took Without Knowing
If you have applied for a corporate role at a mid-size or large company in the last five years, there is a reasonable chance you completed an SHL assessment. The company administers over 30 million assessments annually across 150 countries. The OPQ is just one product in their portfolio, but it is the one most likely to appear in professional hiring pipelines for management, finance, consulting, and corporate strategy roles. The next time an employer asks you to complete a “short questionnaire” as part of your application, read the fine print. It might be 25 minutes. It might feel casual. But somewhere on the other end, a personality profile is being generated—and someone is reading it before they read your CV.
