Key Takeaways

The Oliver Wyman online assessment screens you on numerical reasoning and cultural fit before you ever speak to an interviewer, so accuracy under time pressure and honest, values-aligned answers are what get you through.

The assessment usually has two parts: a competency assessment and a timed numerical reasoning test, with a verbal reasoning test added for some roles

Budget 45 to 60 minutes total, with the numerical section carrying the most weight on whether you advance

The numerical test rewards speed and accuracy on charts, tables, percentages, and growth rates, not advanced math

Many versions use negative marking, so only answer when you are confident and never blind-guess

The competency assessment maps to Oliver Wyman's five values, so answer honestly rather than trying to game it

What Is the Oliver Wyman Online Assessment?

The Oliver Wyman online assessment is a digital pre-interview screen sent by email once your application is accepted. It typically combines a values-based competency assessment with a timed numerical reasoning test, and some roles add a verbal reasoning test. Your results help decide who advances to first-round interviews.

This is a relatively new gate in the firm's process, added to screen a larger and more diverse pool of applicants efficiently. The good news is the format is predictable once you know what each section measures. The bad news is the numerical test is timed and tightly scored, so weak preparation shows up fast.

In my experience at Bain, screens like this are not designed to trick you. They exist to filter out candidates who cannot work quickly with numbers or whose values clearly clash with the firm before a single interviewer's time is spent.

Where Does the Assessment Fit in the Recruitment Process?

The online assessment sits early in the process, right after your application clears the initial review. Oliver Wyman, now part of the expanded Marsh brand, invites screened applicants by email to complete the test within a set window, often around 7 days.

Here is the typical sequence:

Application: submit your resume and cover letter through the firm's careers portal
Online assessment: complete the competency and numerical sections within the deadline
First-round interviews: conversational and case interviews with consultants
Final-round interviews: more case and fit interviews, sometimes with partners

A strong application is what earns the invite in the first place, so a sharp consulting resume matters before the assessment ever lands in your inbox. Once you pass the screen, the next hurdle is the Oliver Wyman case interview, which is where most candidates are made or broken.

Case interviews carry more weight than the online screen. If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days.

What Sections Are on the Oliver Wyman Online Assessment?

The assessment is built around two core sections, with a third added for some roles and regions. Each one measures a different thing, so you cannot prep for all of them the same way.

1. Competency assessment

The competency assessment shows you short scenarios drawn from day-to-day life at Oliver Wyman and asks how you would respond. The goal is to see how well your instincts and values line up with the firm's culture. There are no objectively correct answers in the way a math question has one.

You will often pick which response is most like you and least like you, or rate how strongly you agree with a statement. Some versions also ask you to flag the strengths you showed in past work and extracurricular experiences. Answer honestly, because the scenarios are designed to catch inconsistency when you try to perform an idealized version of yourself.

2. Numerical reasoning test

The numerical reasoning test is the section that screens most candidates out. You read data from charts and tables and answer multiple-choice questions involving percentages, ratios, growth rates, and averages. The test is timed and scored, and the pressure is the hard part rather than the math.

The style sits closer to a GMAT or standard graduate numerical reasoning test than to a gamified case simulation. You will not face the systems-thinking puzzles some other firms use. You will face clean data interpretation that you must do quickly and accurately, sometimes with interactive tables or tabs you click through to reveal more data.

3. Verbal reasoning test (some roles)

For certain roles and regions, you may also sit a verbal reasoning test. This section gives you passages of text and asks whether statements are true, false, or cannot be determined from the passage. It rewards careful reading and the discipline to answer only from the information given, not from outside knowledge.

How Is the Numerical Reasoning Test Structured?

The numerical reasoning test is typically a timed, multiple-choice section of up to 20 to 30 questions completed in roughly 20 to 30 minutes. That leaves you about a minute per question, which is why pacing decides outcomes. Exact counts and timing shift by role, region, and year, so treat any single number as a guide rather than a guarantee.

Here is what to expect on the key mechanics:

Element	What to expect
Question count	Up to 20 to 30 multiple-choice questions, varying by role and year
Time	Roughly 20 to 30 minutes, about a minute per question
Format	Charts, tables, and data sets, sometimes with interactive tabs
Scoring	Many versions apply negative marking, so wrong answers can cost points
Calculator	Usually allowed, but speed still depends on strong mental math
Cut-off	No officially published pass mark, so aim for high accuracy

The negative marking is the detail most candidates miss. When a wrong answer subtracts points, blind guessing on every question can pull your score down rather than up. Skip the question you cannot crack, bank the ones you can, and come back if time allows.

Here is an illustrative example of the kind of question you might see.

Example: A company sold 4 million units last year at $25 each. This year, unit sales grew 15% and the price rose to $28. By what percentage did total revenue increase?

Last year's revenue was 4 million times $25, or $100 million. This year's units came to 4.6 million, and at $28 each that is $128.8 million. The increase is $28.8 million on a $100 million base, so revenue grew 28.8%.

Notice the trap. The price rose about 12% and volume rose 15%, so a rushed candidate might add them to 27% and miss the compounding effect. Speed without accuracy is how good math students still fail this section.

How Does the Competency Assessment Map to Oliver Wyman's Values?

The competency assessment is a cultural-fit filter built on Oliver Wyman's five core values. According to Oliver Wyman's careers site, those values are Be Brave, Lead With Heart, Strive For Breakthroughs, Work As One, and Own Our Impact. The scenarios you rate are designed to surface whether you naturally act in line with them.

Use this table to understand what each value signals and how it shows up in the assessment.

Value	What it means	How it shows up
Be Brave	Stand behind your beliefs and persevere through difficulty	Scenarios about raising a hard truth with a client or team
Lead With Heart	Combine passion with rigor and support the people around you	Choices that weigh empathy against pure results
Strive For Breakthroughs	Pursue ambitious ideas and uncommon insight	Scenarios rewarding a fresh approach over the safe default
Work As One	Build trust and achieve together what you could not alone	Choices about collaboration versus going solo
Own Our Impact	Act with integrity and hold yourself to high standards	Scenarios testing accountability when something goes wrong

Keep these values in mind, but do not contort every answer to fake the firm's culture. The strongest candidates answer how they would actually behave, and that authentic version happens to align with the values because they belong at the firm. The same alignment carries straight into your Oliver Wyman behavioral interview later in the process.

Behavioral and fit questions trip up more candidates than people expect. My fit interview course shows you how to align your stories with a firm's values without sounding rehearsed.

How Do You Prepare for the Oliver Wyman Online Assessment?

Effective prep splits cleanly across the two sections: drill timed numerical reasoning, then study the firm's values for the competency part. You do not need months, but you do need focused, timed practice rather than passive reading.

Follow this plan in the days before your test.

Practice timed numerical tests: work through chart-and-table questions under a strict clock so the pace feels normal
Drill core math: get fast at percentages, percentage change, ratios, growth rates, and averages
Sharpen mental math: build speed so the calculator is a backup, not a crutch
Study the five values: read them on the firm's careers site so the competency scenarios feel familiar
Do a dry run: check your internet connection and find a quiet space before the real attempt

The single highest-return habit is building fast, accurate mental math, because it pays off on the numerical test and again in every case interview that follows. Treat the calculator as a safety net for the heaviest calculations only.

What Are the Best Tips to Pass?

Passing comes down to managing time, protecting your score from negative marking, and answering the competency section like yourself. These tips target the mistakes I see candidates make most.

Tip #1: Prioritize accuracy over finishing

With negative marking in play, a wrong answer is worse than a blank one. It is better to answer fewer questions correctly than to rush through every one and rack up penalties.

Tip #2: Triage the questions

Bank the quick wins first and flag anything that needs heavy calculation. Coming back to a hard question with two minutes left beats burning four minutes on it early and running out of time.

Tip #3: Read the chart before the question

Spend a few seconds orienting to the axes, units, and what each column means. Half of the errors on data questions come from misreading the table, not from the math.

Tip #4: Answer the competency section honestly

The scenarios cross-check your answers for consistency, so a manufactured persona tends to unravel. Respond as you genuinely would while keeping the firm's values in the back of your mind.

Tip #5: Set up your environment

Slow loading between questions eats into a timed test, so use a stable connection and a quiet room. Have scratch paper, a pen, and a calculator ready before you start.

Clearing the Oliver Wyman online assessment is mostly a preparation problem, not a talent problem, so the single most important action is to practice the numerical section under a timed clock until speed and accuracy stop competing with each other.

Frequently Asked Questions

What is the Oliver Wyman online assessment?

The Oliver Wyman online assessment is a pre-interview screen sent by email after your application is accepted. It usually has two parts: a values-based competency assessment and a timed numerical reasoning test. Some roles and regions also add a verbal reasoning test. Your performance helps decide whether you advance to first-round interviews.

How long is the Oliver Wyman online assessment?

Plan for 45 to 60 minutes in total. The competency assessment usually takes 20 to 30 minutes, and the numerical reasoning test is typically a timed 20 to 30 minute section with up to 20 to 30 questions. Exact timing varies by role, region, and the year you apply.

Is the Oliver Wyman numerical reasoning test hard?

It is one of the tougher consulting numerical tests, mostly because of the time pressure and the scoring. You read charts and tables and solve percentage, ratio, and growth problems quickly. The math itself is not advanced, but the pace and accuracy demands catch out candidates who do not practice under timed conditions.

Does the Oliver Wyman assessment have negative marking?

Many versions of the numerical reasoning test apply negative marking, meaning a wrong answer can subtract points. Because of this, you should only answer when you are confident rather than guessing on every question. The competency assessment is not scored for right or wrong answers in the same way.

Can you use a calculator on the Oliver Wyman online assessment?

You are usually allowed a calculator on the numerical reasoning test. Even so, leaning on it for every step slows you down. Practice fast mental math for percentages and ratios so you only reach for the calculator on the heavier calculations.

How do you pass the Oliver Wyman online assessment?

Practice timed numerical reasoning tests built around charts, tables, percentages, and growth rates until speed and accuracy are second nature. For the competency assessment, answer honestly while keeping Oliver Wyman's five values in mind. Prioritize accuracy over completion, since unanswered questions usually hurt less than wrong ones.
