The battery candidates report
Game-based and immersive assessments measure the same substrate as classic tests — numeracy under time, deduction, working memory, behavioural tendencies — through interactive tasks. Training the underlying skills transfers; memorising answers cannot, because there are none to memorise.
Selection stacks in management consulting (mbb), normally run the online battery as the first cut — before any interview — which is why it eliminates more candidates than every later stage combined. The preparation that pays is format preparation: the items change, the demands do not.

What McKinsey says it values
McKinsey publishes its own framework, and behavioural screening tends to mirror the published values. Knowing them will not hand you answers — questionnaires flag inconsistent role-play — but it tells you which of your genuine strengths are worth letting through clearly:
- Put client interests first
- Adhere to highest ethical standards
- Preserve the obligation to dissent
- Develop a non-hierarchical meritocracy
What the screening reads for
Across candidate reports and the sector's published role profiles, the behavioural side of McKinsey screening effectively reads for: structured problem-solving · drive & entrepreneurship · personal impact. The aptitude side is simpler to summarise — accuracy at pace — and it is also the side that responds fastest to practice.
How to prepare
Run the timed formats until the interface and the pacing are boring, then use the per-exercise rank to find the module that would drag your profile down and concentrate there. For the personality questionnaire, take a full practice pass first: seeing your own profile before the employer does is the one legitimate edge available, and answering consistently beats answering “perfectly”.
Frequently asked questions
What assessments does McKinsey use in hiring?
Candidates consistently report the following in McKinsey's selection process: Solve (problem-solving game) + personal-fit assessment. Processes change by role, region and year, so treat your own invitation email as the definitive list — and this page as preparation for the formats it is most likely to name.
Can I prepare for the McKinsey assessment?
Yes — the formats train even when the exact items cannot be known. Timed numeracy, deductive logic and interactive modules all reward familiarity: candidates routinely move several bands between a cold first attempt and a practised one. For the personality questionnaire, practice shows you your own profile before McKinsey sees it, which is what an honest preparation can deliver.
Is Persona Prep affiliated with McKinsey?
No. Persona Prep is an independent practice platform with no connection to McKinsey or to any test publisher. We build practice for the assessment FORMATS candidates report; we never reproduce any company's or publisher's actual test content.
What is McKinsey looking for in the personality questionnaire?
McKinsey publishes its own framework — Put client interests first, Adhere to highest ethical standards, Preserve the obligation to dissent, Develop a non-hierarchical meritocracy — and behavioural screening tends to mirror it. In practice that means the questionnaire reads for: structured problem-solving; drive & entrepreneurship; personal impact. Consistency matters more than a "perfect" profile: modern questionnaires flag contradictory answering.
