Big 4 Personality Tests: Deloitte, EY, PwC, KPMG

Which tests the Big 4 use

Deloitte and PwC rely primarily on the SHL OPQ32, a 104-item forced-choice questionnaire that measures 32 behavioral dimensions. EY frequently uses the Hogan HPI, which assesses seven personality scales linked to professional performance. KPMG varies by office and country, alternating between the SHL OPQ32, Saville Wave, and occasionally proprietary assessments developed internally.

These tests are administered online, typically after the CV screening and before interviews. You receive an email link with a few days to complete the questionnaire. Duration varies from 25 to 40 minutes depending on the format. The common thread across all of them is the forced-choice format, which prevents candidates from artificially maximizing every dimension.

Understanding which test your target firm uses gives you a concrete preparation advantage. An OPQ32 with its 104 triads of statements feels very different from a Hogan HPI with its agree/disagree format. Knowing what to expect eliminates the surprise factor that degrades first-time performance.

Consulting vs audit profiles

In consulting, firms look for profiles with strong assertiveness, the ability to take a position in front of a client and defend a recommendation. Innovation, tolerance for ambiguity, and social energy are also highly valued. A consultant who scores low on these dimensions will be perceived as a risk, even if their technical skills are strong.

In audit, the expected profile is different. Firms prioritize rigor, reliability, and process adherence. A high score in conscientiousness and discipline is virtually essential. Assertiveness remains important, but it manifests differently: it is about knowing how to ask the right questions of the client, not about selling a strategic vision.

In transaction services and advisory, the profile approaches that of consulting with additional emphasis on stress resilience and the ability to work under extremely tight deadlines. Candidates for these roles should expect the personality assessment to weight composure and drive heavily.

Key dimensions assessed

Regardless of the service line, five dimensions consistently appear in Big 4 evaluation frameworks. The first is influence: your ability to persuade, negotiate, and structure an argument. The second is resilience: how you react to pressure, criticism, and setbacks. These two dimensions are non-negotiable across all Big 4 roles.

The third dimension is results orientation: your level of ambition, persistence, and tendency to set high goals. The fourth is collaboration: your ability to work in teams, integrate others' contributions, and manage conflict constructively. The fifth is adaptability: your openness to change, intellectual curiosity, and capacity to operate in uncertain environments.

Preparation strategies

The first step is to identify precisely the target position and service line. An audit candidate who prepares like a consultant will make positioning errors in their responses. Read the job description carefully, identify the behavioral competencies mentioned, and translate them into personality dimensions. This is not manipulation but informed self-presentation.

Next, familiarize yourself with the forced-choice format. In an OPQ32, each block presents four statements: you must choose the one that describes you most and the one that describes you least. This format is disorienting the first time. Practice eliminates the surprise effect and improves response consistency by 10 to 15 percent.

Finally, work on your internal consistency. SHL and Hogan tests incorporate social desirability and consistency scales. If your responses are contradictory, the report will flag it to the recruiter, who will steer the interview toward those inconsistencies. Practicing beforehand helps you develop a stable, coherent response pattern.

What causes Big 4 candidates to fail

The most frequent mistake is overplaying the charismatic leader profile. Candidates maximize assertiveness and ambition while minimizing cooperation and empathy. The result is an unbalanced profile that experienced recruiters spot immediately. The firms are looking for collaborative leaders, not individualists. A profile that screams authority but lacks teamwork raises red flags.

The second mistake is neglecting preparation entirely. Many candidates spend weeks on case interviews but completely ignore the personality test. Yet an unfavorable report can eliminate a candidate before they even reach the interview stage. Personality is not a secondary filter in Big 4 recruitment; it is a decision criterion in its own right.
