Oliver Wyman interview questions and tips for the application process

The journey to securing a position at Oliver Wyman is challenging but achievable with the right preparation. Oliver Wyman seeks candidates who are not only intellectually capable but also business-minded, innovative thinkers, and culturally sensitive. Understanding what differentiates Oliver Wyman—its open team culture, industry specialization, and case team model—will significantly enhance your chances during the application process.

The overview of Oliver Wyman application process

There are five major steps in the Oliver Wyman application process:

1. Online Application
2. Online Test
3. Screening Interview
4. Case Interviews
5. Outcome

The process begins with the online application, where you’ll upload your CV and cover letter on Oliver Wyman's careers website. While it seems straightforward, it's essential to craft your application documents in a way that clearly demonstrates your value and fit for the company culture.

Shortlisted candidates then proceed to the online test, a computer-based assessment that evaluates your numerical, verbal, and logical reasoning abilities. This serves as a preliminary filter, testing basic skills required for consulting. Applicants who perform well in the online test move on to the screening interview, typically conducted via telephone or video. This 30-45 minute interview tests your motivation for consulting, your knowledge of Oliver Wyman’s business, and your overall cultural fit.

The most challenging part is the case interviews, where you'll be presented with 2-3 real business problems that assess your analytical thinking, systematic problem-solving approach, and ability to simplify complex issues. Finally, selected candidates are notified of the decision within 1-2 weeks of completing all interview rounds. While the final decision and online application processes are fairly straightforward, the online test, screening interview, and case interviews require thorough preparation.

1. Online application

Your online application is the foundation of your candidacy and an opportunity to make a lasting impression on Oliver Wyman’s recruiting team. The firm receives thousands of applications each year, so it's crucial to create materials that stand out and accurately reflect your qualifications and experience.

Optimizing your CV

When structuring your CV, focus on achievements and attributes that align with Oliver Wyman’s core values: impact, leadership, and problem-solving abilities. Organize your CV into clear sections—skills, education, experience, and extracurricular activities—and use bullet points to describe your accomplishments. Emphasize quantifiable outcomes. For example, instead of saying, “worked on a consulting project,” say, “developed a market entry strategy for a fintech startup that identified $5M in potential revenue streams.”

Structuring your cover letter

Your cover letter should complement your CV and tell a compelling story about your interests and background. Avoid generic statements about consulting and focus on something concrete about Oliver Wyman’s business and culture. Read recent work or thought leadership articles on the firm’s website and reference them. For example, you could mention how Oliver Wyman’s research on digital transformation in banking relates to your field of study or internship experience.

Pay attention to tone and style. The opening paragraph should capture the reader’s attention by showcasing your genuine interest in Oliver Wyman. The second paragraph should highlight 2-3 key experiences that demonstrate the skills needed for the job, and the third paragraph should restate your enthusiasm and what you can bring to the company. Keep the letter concise—no more than one page—and proofread it carefully to avoid formatting or grammatical mistakes.

2. Cracking the Oliver Wyman online test

The online test is your first substantial challenge in the Oliver Wyman recruitment process. It typically consists of three main sections: numerical reasoning, verbal reasoning, and logical reasoning, all designed to assess the cognitive abilities needed for consulting.

• Numerical reasoning: You’ll be asked to interpret numerical data in tables, charts, and graphs and perform calculations. Common question types include percentage differences, growth percentages, and profit margins. The challenge lies in completing these tasks within a time limit while identifying the most relevant information from complex data.
• Verbal reasoning: This section evaluates your ability to read and analyze business-related texts. You’ll be given passages and asked multiple-choice questions to test your ability to differentiate between facts, assumptions, and conclusions. Time is crucial as the passages are lengthy, and the questions are designed to test your comprehension and inference skills.
• Logical reasoning: This section tests your abstract problem-solving skills, including pattern recognition, sequence completion, and deductive reasoning. While the questions may seem abstract, these skills are essential for consulting.

Preparation tips

To prepare for the online test, start by taking practice diagnostic tests to identify your strengths and weaknesses. Numerous websites offer real practice questions used by Oliver Wyman. Focus on time management during practice—learn to prioritize questions and recognize when to move on to the next one. For numerical reasoning, improve your mental arithmetic, especially percentages, ratios, and simple algebra. For verbal reasoning, practice active reading to speed up comprehension. For logical reasoning, engage in regular exercises like puzzles to sharpen your pattern recognition skills.

3. Acing the screening interview

The screening interview is your first personal interaction with Oliver Wyman and a key test of your cultural fit and interest in consulting. This 30-45 minute interview, typically conducted by a consultant or HR professional, is designed to learn more about you, your background, and your fit with the firm’s culture.

Expect both behavioural and motivational questions. You may be asked, “Why consulting?” or “Why Oliver Wyman?” along with questions about teamwork, leadership, and problem-solving. The interviewer will evaluate not only your responses but also your communication style—your ability to think on your feet and maintain focus throughout the interview.

Answering behavioural questions

Use the STAR method (Situation, Task, Action, Result) to structure your answers. For example, when asked about a leadership experience, describe the specific setting (Situation), the task at hand (Task), the actions you took (Action), and the outcome (Result). This approach helps you deliver concise yet comprehensive answers that highlight your contributions and results.

Preparation tips

To prepare for the screening interview, research Oliver Wyman’s latest projects, culture, and the industries it focuses on. Visit the company website, read recent reports and press releases, and create a few thoughtful questions to ask your interviewer. This shows that you’ve done your homework and are genuinely interested in the firm.

4. Mastering Oliver Wyman case interviews

Case interviews are the toughest and most critical part of Oliver Wyman’s hiring process. These interviews simulate real consulting cases, testing your problem-solving, analytical thinking, and communication under pressure.

Oliver Wyman’s case interviews typically follow a standard pattern:

• The interviewer presents a business problem.
• You ask clarifying questions to understand the issue fully.
• You break down the problem using a structured approach.
• You apply quantitative analysis where relevant.
• You recommend a solution based on your findings.

Types of cases

• Market entry: These cases involve advising a company on whether to enter a new product or geographic market. You’ll need to assess market size, growth potential, competition, customer needs, and more.
• Profitability: In these cases, you’ll diagnose and address business performance issues, such as declining profit margins. You’ll analyze revenue drivers and cost structures.
• Investment: These cases focus on evaluating acquisitions or investments. You’ll need to consider value, synergy potential, and strategic fit.

Preparation tips

Start by familiarizing yourself with common case formats like market entry, profitability, and pricing. However, don’t treat them as rigid formulas—Oliver Wyman interviewers will look for creativity and resourcefulness in your approach. Practice with mock cases and get feedback on your thought process and presentation. Focus on communicating your approach clearly and succinctly, and engage in a conversational dialogue with the interviewer.

5. The outcome

Oliver Wyman typically makes its decision within 1-2 weeks after the case interviews. During this time, review your performance and consider sending a polite thank-you email to your interviewers, reaffirming your interest in the company. If you don’t receive an offer, ask for constructive feedback to improve for future applications. Many candidates apply several times before receiving an offer.
