Korn Ferry Assessment: What to Expect and How to Prepare
You applied to a bank, a retailer or a ministry. A week later an email arrives with a Korn Ferry logo and a link to "complete your assessment". Most candidates have the same reaction: who is Korn Ferry, and why are they testing me? This guide answers that, walks through each part with a worked example, and gives you a realistic preparation plan. If you already know what you are facing and just want to practise, our Korn Ferry practice tests are built around exactly these formats.
Who Is Korn Ferry?
Korn Ferry is a US-listed organisational consultancy headquartered in Los Angeles. It started life in 1969 as an executive search firm, the people who quietly recruit chief executives and board members, and it is still one of the largest names in that business. It has since grown well beyond headhunting. It bought the UK test publisher Talent Q in 2014 and the consultancy Hay Group, known for job evaluation and reward work, in 2015. In 2018 it retired its sub-brands, including Hay Group, Futurestep and Lominger, and began going to market as a single "Korn Ferry" brand.
Today the company reports its business in several segments: consulting, digital (its technology and assessment platforms), executive search, professional search and interim, and recruitment process outsourcing (RPO).
Why a Different Employer Sends You a Korn Ferry Test
Korn Ferry sells its assessments to other organisations. When a company licenses the tools, it sends you an invitation through Korn Ferry's platform, but the company remains your counterpart. It decides which tests you take, which comparison group you are measured against and what score is good enough. Korn Ferry provides the instruments, not the job.
Some employers also outsource recruitment to Korn Ferry's RPO or professional search teams, in which case a Korn Ferry consultant may run your interviews too. The tests are the same family either way.
The Korn Ferry Candidate Journey
There is no single fixed Korn Ferry assessment. Employers mix and match modules. A typical journey for a graduate or mid-level role looks like this:
- Invitation email. A link, a deadline (often a few days to a week) and a list of the modules you will take. It tells you exactly what to practise.
- Online ability tests. Usually one to three of numerical, verbal and logical reasoning, taken unsupervised at home.
- Personality or competency questionnaire. Untimed or loosely timed, measuring how you tend to work rather than what you can do.
- Interview or assessment centre. For senior and graduate scheme roles, possibly a day of exercises such as an in-tray, a presentation and a competency interview.
At executive level, Korn Ferry also runs its KF4D assessment, which looks at four dimensions: competencies, experiences, traits and drivers.
The Ability Tests: Elements and Its Adaptive Format
Korn Ferry's best-known ability tests come from the Talent Q range and are called Elements. They cover numerical, verbal and logical reasoning. Two features set them apart from the tests most candidates have practised on, and both trip people up the first time.
They are adaptive. You start on a question of medium difficulty. Answer correctly and the next one gets harder; get it wrong and it gets easier. The test homes in on your level, so the score depends on how difficult the questions you answered correctly were, not just how many you got right. If the test feels hard, that is usually a good sign.
Each question has its own timer. Rather than one clock for the whole test, Elements gives you a fixed amount of time per question, displayed on screen. The exact allowance differs by test type and by version, so we will not quote a number your invitation may contradict. You cannot "bank" time on easy questions, and you cannot skip ahead and come back. When the timer runs out, the test moves on.
Combine those two features and you get the most important tactical rule for Korn Ferry ability tests: always submit an answer before the timer expires. A reasoned guess has a chance of being right; a blank does not.
Read the instruction line on every question: some items ask for more than one answer.
Numerical Reasoning
You get a table or chart, usually business data, and a question that needs one or two calculation steps. The maths is school level: percentages, ratios, averages, currency conversion. The difficulty is doing it accurately while a timer counts down.
Worked example. A table shows a company's staff numbers by region. Northern region: 240 employees last year, 276 this year. Southern region: 310 last year, 341 this year. The question asks which region grew faster in percentage terms, and by how many percentage points.
Northern grew by 36 on a base of 240, which is 15%. Southern grew by 31 on a base of 310, which is 10%. Northern grew faster, by 5 percentage points. The trap answers are "Northern, by 5%" when the options distinguish between percent and percentage points, or Southern because 341 is the bigger number.
Our article on Korn Ferry numerical reasoning tests has more examples and calculator tips.
Verbal Reasoning
You read a short passage and judge a statement or answer a question about it, using only what the passage says. This is where general knowledge becomes a liability.
Worked example. The passage says: "Since the company introduced a four-day week for its support team, customer complaints have fallen by a fifth. Management attributes this to lower fatigue, although the same period saw the launch of a redesigned self-service portal."
Statement: "The four-day week caused the drop in complaints."
Instinct says True. The correct judgement: you cannot conclude this. Management attributes the fall to the four-day week, and the passage explicitly offers a competing explanation. The skill is noticing the gap between a claim and what the text establishes. Words like "attributes", "suggests", "most" and "some" are where the points are won or lost.
Logical and Abstract Reasoning
Logical reasoning in the Korn Ferry range uses shapes instead of words or numbers. You see a series or grid of figures and have to identify the rule that connects them, in the tradition of Raven's Progressive Matrices.
Worked example. Four boxes in a row. Each contains a square with a black dot in one corner. Box one: dot top-left. Box two: dot top-right. Box three: dot bottom-right. Box four: dot bottom-left. Meanwhile, the number of small lines along the bottom of each box goes 1, 2, 3, 4. Which figure comes next?
The dot moves one corner clockwise each step, so it returns to top-left. The lines increase by one, so there should be five. The answer is the square with the dot top-left and five lines. Distractors typically get one of the two rules right.
The fastest way to solve these under a per-question timer is a checklist: position, rotation, number, size, shading, and whether two rules run at once. Same order, every time.
The Personality and Competency Questionnaires
Korn Ferry's questionnaires come in several flavours. Dimensions is the Talent Q personality questionnaire, which maps your preferred working style across areas such as how you relate to people, how you approach tasks and how you handle pressure. Aspects is a lighter range built for screening large numbers of applicants. At senior levels, the KF4D framework adds questions about your motivations (drivers) and your career experiences.
These are not tests in the pass-or-fail sense, but they are not decorative either. Your profile is compared with what the employer has defined as important for the role.
Worked example. You might be asked to rank or rate statements such as:
- "I like to have a clear plan before I start a task."
- "I enjoy persuading others to change their minds."
- "I stay calm when deadlines move unexpectedly."
No single statement has a right answer; a controller role might reward the first, a sales role the second. What hurts candidates is inconsistency: rating yourself as extremely structured in one section and extremely spontaneous in another, because you were guessing what the employer wanted each time.
My advice is dull but effective: answer as you are on a normal working day, not on your best day and not on your worst. Keep two or three real work situations in mind as reference points, and answer quickly.
In-Tray and E-Tray Exercises
For senior roles, graduate schemes and some public sector posts, the online tests can be followed by an assessment centre. A common exercise there is the in-tray, or its digital cousin the e-tray: you step into a role and work through an inbox of emails, reports and requests in a limited time.
Worked example. You are the new operations manager. You have 45 minutes and your inbox holds, among others: a complaint from your biggest client about a late delivery, a reminder that a team member's leave request needs approval by today, an invitation to a networking lunch next month, and a warning from IT that a system update tonight may interrupt order processing.
A strong response prioritises the client complaint and the IT warning, because both affect customers now, and links them: is the late delivery related to the systems issue? It approves or delegates the leave request because the deadline is hard, and parks the lunch invitation. Assessors watch what you prioritise, what you delegate, and whether you connect items. Doing everything yourself is rarely right.
Our guide to assessment centres covers the other exercises.
How Korn Ferry Results Are Used
Your performance on the ability tests is converted into a score that compares you with a norm group: a reference population of people who took the same test, such as graduates or managers. Results are often reported as a percentile or on a banded scale. A 70th percentile means you scored higher than about 70% of that comparison group.
What the employer does with that is up to the employer. Some set a cut-off and screen out everyone below it. Others combine ability scores with the questionnaire into an overall fit indicator against a role profile, and use it alongside your CV and interview. For leadership roles, Korn Ferry offers benchmarks drawn from its large database of assessed professionals, but no client's exact weighting is public. Be wary of anyone who claims to know the exact pass mark for your application.
Because comparisons are relative, you do not need a perfect score, and a weaker module can sometimes be offset elsewhere. Do not abandon the session if one test goes badly.
An Honest Preparation Plan
Preparation will not turn an average reasoner into a genius. It does remove the penalty for unfamiliarity, which is unusually large with an adaptive, per-question-timed format.
Days 1 to 2: diagnose. Take one timed practice test of each type your invitation lists. Do not study first. Note which type felt worst and where you ran out of time.
Days 3 to 7: build speed on your weak spot. Short daily sessions of 20 to 30 minutes beat one long Sunday cram. Drill percentage change and table reading, separate claims from facts, and run your shape checklist until it is automatic. Our general guide to online aptitude tests covers the broader techniques per test type.
Days 8 to 10: rehearse the format. Practise under per-question time limits, not just an overall timer. This is the single most Korn Ferry-specific thing you can do. The Korn Ferry training package simulates this format so the real test does not feel like the first time.
The day itself. Re-read the invitation for modules, deadline and calculator rules. Use a laptop, not a phone, keep scrap paper and a calculator nearby, and test when you are fresh, not at 11 pm after a full working day.
If you are also applying to employers who use other publishers, the formats differ in useful ways. Our SHL test guide explains how SHL's tests compare, so you can adjust your practice instead of starting over.
FAQ
Why am I taking a Korn Ferry test when I applied to a different company?
Korn Ferry is a consultancy that sells its assessment tools to other organisations. The employer you applied to has licensed Korn Ferry's tests and uses them in its own selection process. Korn Ferry hosts the platform; the hiring company sets the benchmark and makes the decision.
Is the Korn Ferry assessment the same as Talent Q?
Largely, yes. Korn Ferry acquired the UK test publisher Talent Q in 2014, and the Talent Q products, including the adaptive Elements ability tests and the Dimensions personality questionnaire, now run under the Korn Ferry name. Many invitations and practice resources still use the Talent Q labels.
Can I go back and change an answer in the Korn Ferry ability tests?
Generally no. The Elements tests are adaptive: each answer influences the difficulty of the next question, so once you submit and the timer moves on, the question is closed. Treat every answer as final and do not leave a question unanswered when the clock runs out.
Can you fail the Korn Ferry personality questionnaire?
There is no pass mark in the sense of right and wrong answers, but your profile is compared with what the employer considers important for the role, so it can count against you. The best approach is to answer honestly and consistently. Trying to play an ideal candidate tends to produce an inconsistent, flat profile that raises more questions than it answers.
How long should I prepare for a Korn Ferry assessment?
One to two weeks of short daily sessions is enough for most candidates. Spend most of that time on timed numerical, verbal and logical practice so the per-question timer feels familiar, and set aside an evening to reflect on your work examples for the personality questionnaire and any later interview.
Conclusion
A Korn Ferry assessment looks intimidating mainly because it arrives from a company you did not apply to, in a format you have probably not seen. The parts that are genuinely different, the adaptive difficulty and the timer on every question, are exactly the parts practice handles best. Learn the format, always submit an answer, be consistent in the questionnaire, and you will be measured on your ability rather than your surprise.
