The Aon case study interview is a 30 to 60-minute exercise where you and an interviewer solve a business problem together. It is the hardest part of Aon's hiring process. You will face one to two cases in every round, so you need to pass all of them to get an offer.

 

Aon hires through Aon Inpoint and its Strategic Advisory group, both of which lean heavily on insurance, risk, and human capital cases. This guide gives you the exact six-step method, twelve real example cases, the full interview process, and the tips that work.

 

But first, a quick heads up:

 

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

 

What Is an Aon Case Study Interview?

 

An Aon case study interview, also called a case interview or simply a “case,” is a 30 to 60-minute exercise in which you and the interviewer work together to develop a recommendation for a business problem. Aon uses cases to test how you think, not what you already know.

 

These business problems can be anything that real companies face:

 

• A retail company is considering entering a new market segment. Analyze whether they should proceed

 

• A pharmaceutical company is launching a new drug. How should they price it?

 

• A tech startup is experiencing stagnant growth. Identify potential avenues for expansion

 

• An airline is experiencing delays. Identify potential causes and propose solutions

 

Aon case study interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that Aon solves for their clients. Many Aon case study interviews are based on actual projects that interviewers have worked on.

 

While consulting projects typically last between 3 to 9 months, Aon case study interviews condense solving the business problem into just 30 to 45 minutes.

 

Aon case study interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.

 

They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.

 

Although Aon case study interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed. You can solve every case using structured thinking and basic business sense.

 

Who Is Aon and Which Teams Use Case Interviews?

 

Aon is one of the world's largest professional services firms, with roughly 60,000 employees across more than 120 countries and over $12 billion in annual revenue. Aon advises clients on risk, insurance, reinsurance, retirement, health, and human capital.

 

Not every Aon role uses a case interview. Cases show up most often in Aon's consulting and strategy teams. The two you should know are:

 

Aon Inpoint: A global strategy consulting practice focused exclusively on the insurance industry. Inpoint helps insurers and brokers find profitable growth and improve operations. It serves clients from offices in Chicago, New York, London, Rotterdam, Singapore, Sydney, and Hong Kong.

 

Aon Strategic Advisory and Strategy & Technology Group: Teams that run strategy and total rewards projects, such as compensation benchmarking, talent strategy, and market entry studies for corporate clients.

 

If you are interviewing for an analyst or consultant role on one of these teams, expect cases. If you are interviewing for a benefits, broking, or actuarial role, you are more likely to get technical and competency questions instead of a full strategy case.

 

How Do Aon Cases Differ From a Typical Consulting Case?

 

Aon cases follow the same structure as any consulting case, but the scenarios skew toward Aon's areas of expertise: insurance, risk, and human capital. Instead of a generic profitability case, you might be asked to size an insurance market or weigh the cost and value of an employee wellness program.

 

Here is how Aon cases tend to differ:

 

Element	Typical Strategy Case	Aon Case
Industry focus	Any industry	Insurance, risk, reinsurance, benefits, retirement
Common case types	Profitability, market entry, M&A	Insurance market entry, benefits design, pension performance, risk mitigation
Data style	Mostly quantitative	Mix of qualitative judgment and targeted math
Format	Often interviewer-led	Interviewer-led, plus a case presentation in the superday

 

You do not need insurance knowledge to pass. You do need to be comfortable structuring a problem and doing math quickly. The labels change, but the thinking is the same.

 

What Is the Aon Interview Process?

 

The Aon interview process for consulting and strategy roles usually has two stages: a first-round phone or video interview, followed by a superday with multiple cases and a behavioral interview. The full process takes about 29 days on average, based on Glassdoor data from over 1,000 candidate reports.

 

Aon First Round Interview

 

The first round is usually a 30 to 45-minute phone or video interview. It includes one to two short cases and a few fit questions such as why consulting and why Aon. The goal of this round is to screen for structured thinking and genuine interest in the firm.

 

Aon Final Round Interview (Superday)

 

The final round is a superday, often run by the Inpoint team. Recent candidates report a superday made up of one case presentation, two live cases, and one behavioral interview.

 

The behavioral portion uses standard consulting behavioral questions such as “tell me about a time you resolved conflict on a team” and “give an example of a time you went above and beyond.”

 

Some Aon teams also add an online aptitude assessment or a one-way recorded video interview before the superday. These test numerical reasoning, logical reasoning, and communication. Ask your recruiter what to expect so nothing catches you off guard.

 

How Hard Is the Aon Interview?

 

Aon interviews are moderately difficult. Candidates rate the process 2.81 out of 5 on difficulty and 61.8% positive on Glassdoor. The cases themselves are not as brutal as MBB cases, but the bar rises in insurance-heavy teams where interviewers expect you to engage seriously with the scenario.

 

What Does an Aon Case Study Interview Assess?

 

Aon case study interviews assess five qualities: logical and structured thinking, analytical problem solving, business acumen, communication skills, and personality and cultural fit. All five can be judged inside a single 30 to 60-minute case, which is what makes the format so effective.

 

1. Logical and structured thinking: Consultants need to be organized and methodical to work efficiently.

 

• Can you structure complex problems in a clear, simple way?

 

• Can you take large amounts of information and identify the most important points?

 

• Can you use logic and reason to reach sound conclusions?

 

2. Analytical problem solving: Consultants work with a lot of data to build recommendations for complex problems.

 

• Can you read and interpret data well?

 

• Can you perform math computations smoothly and accurately?

 

• Can you run the right analyses to draw the right conclusions?

 

3. Business acumen: A strong business instinct helps consultants make the right calls and recommendations.

 

• Do you understand fundamental business concepts?

 

• Do your conclusions make sense from a business perspective?

 

4. Communication skills: Consultants need strong communication to work with teammates and clients.

 

• Can you communicate in a clear, concise way?

 

• Are you articulate in what you are saying?

 

5. Personality and cultural fit: Consultants spend a lot of time in small teams, so fit makes the whole team work better.

 

• Are you coachable and easy to work with?

 

• Are you pleasant to be around?

 

How to Solve an Aon Case Study Interview

 

There are six steps to solving an Aon case study interview: understand the case, structure the problem, kick off the case, solve quantitative problems, answer qualitative questions, and deliver a recommendation. Steps four and five may swap order depending on the case, but the rest stay in sequence.

 

Step 1: Understand the Case

 

Your Aon case study interview begins with the interviewer giving you the background information. While they speak, take meticulous notes on the most important details. Focus on the context of the situation and the objective of the case.

 

Don't be afraid to ask clarifying questions if you do not understand something. You may also want to summarize the background back to the interviewer to confirm your understanding.

 

The most important part of this step is to verify the objective. Not answering the right business question is the quickest way to fail a case study interview.

 

Step 2: Structure the Problem

 

Next, develop a framework to help you solve the case. Case interview frameworks break a complex problem into smaller, manageable components. Think of it as brainstorming ideas and organizing them into categories.

 

Before you start, it is completely acceptable to ask the interviewer for a minute or two to collect your thoughts.

 

Ideally, you want your framework to be as MECE as possible. MECE stands for mutually exclusive and collectively exhaustive. Each element should have zero overlap with the others, and together they should cover all the important areas of the case.

 

Once you have identified the major areas to explore, walk the interviewer through your framework. They may ask questions or offer feedback.

 

Step 3: Kick Off the Case

 

After presenting your framework, you'll start digging into different areas to solve the case. How this begins depends on whether the case is candidate-led or interviewer-led.

 

In a candidate-led case, you propose which area of your framework to start with and give a reason. There is generally no wrong area to pick first.

 

In an interviewer-led case, the interviewer tells you which area to start in or gives you a question to answer directly. Aon case study interviews are generally interviewer-led, but you may occasionally get a candidate-led case.

 

Step 4: Solve Quantitative Problems

 

Your Aon case will most likely have a quantitative element. You might calculate a profitability or financial metric, estimate the size of a market, or estimate a specific figure.

 

The key is to lay out your approach upfront before doing any math. If the interviewer approves your structure, the rest of the problem is just execution.

 

When doing case interview math, talk through your thinking out loud so the interviewer can follow each step. Once you have an answer, explain how it affects the recommendation you are forming.

 

Step 5: Answer Qualitative Questions

 

Your Aon case will likely also have qualitative elements. You may be asked to brainstorm a list of ideas or to give your opinion on a business issue.

 

The key is to structure your answer. When brainstorming, group your ideas into clear categories. When giving an opinion, state your position first, then enumerate the reasons that support it.

 

When you finish, connect your answer back to the case objective. How does it affect the recommendation you are forming?

 

Step 6: Deliver a Recommendation

 

In the final step, present your recommendation and the major reasons behind it. You do not need to recap everything you did, so summarize only the most important facts.

 

It is also good practice to include next steps you would take with more time or data. These can be framework areas you did not explore or open questions you could not fully answer.

 

Learning case interviews on your own can take months. If you want a step-by-step shortcut, my case interview course teaches the full method in as little as 7 days.

 

Aon Case Study Interview Examples

 

Aon does not publish case examples on its website. Below are twelve realistic Aon-style cases compiled from candidate reports and aligned with Aon's focus areas of insurance, risk, and human capital. Practice each one start to finish.

 

Example #1: A large multinational corporation has growing exposure to cyber threats. How would you advise them to strengthen their cybersecurity measures?

 

Example #2: An insurance company is considering entering a new market segment, such as pet insurance. Assess the market potential and recommend a market entry strategy.

 

Example #3: A manufacturing company is facing high employee turnover. What HR strategies would you propose to improve retention?

 

Example #4: A company wants to optimize its employee benefits package to attract and retain talent while managing costs. Develop a plan to balance the two.

 

Example #5: An organization's pension fund is underperforming versus benchmarks. Analyze the causes and recommend investment strategies to improve returns.

 

Example #6: A company wants to launch a health and wellness program for employees. Outline the key components and estimate the return on investment.

 

Example #7: Evaluate the risks of a merger between two companies in different regulatory environments and recommend mitigation strategies.

 

Example #8: An organization must comply with new regulatory requirements. Develop a plan to assess current compliance and implement the changes needed.

 

Example #9: A technology startup is scaling fast and needs to hire many employees quickly. Design a talent acquisition strategy that keeps quality high.

 

Example #10: Analyze employee engagement and satisfaction at a company and propose initiatives to improve morale and productivity.

 

Example #11: A regional insurer is considering whether to open an office in a new country. Build the business case and recommend a resource allocation.

 

Example #12: A reinsurance broker wants to grow its share of a specific market. Identify where the growth could come from and how to capture it.

 

How Do You Tailor Your Framework to Aon's Focus Areas?

 

You tailor your framework for Aon by adding the factors that matter in insurance, risk, and human capital. The structure stays MECE, but the buckets reflect what Aon's consultants actually work on. This shows industry awareness and makes your analysis more relevant.

 

Useful additions by case type:

 

• Risk and insurance cases: Add regulatory compliance, risk exposure, claims experience, and reinsurance options to your framework.

 

• Market entry cases: When the market is insurance or benefits, account for regulation, competitor products, distribution channels, and the claims process.

 

• Human capital cases: For employee and benefits problems, consider engagement, retention, training costs, and workforce planning.

 

• Value drivers: Across all cases, tie your analysis back to cost-effectiveness, operational efficiency, and client satisfaction.

 

Many Aon cases borrow concepts from insurance case interviews and financial services case interviews, so practicing insurer economics and underwriting basics pays off.

 

How Much Does Aon Pay Consulting and Strategy Roles?

 

Aon strategy and consulting analysts earn roughly $76,000 to $93,000 in base salary, with total compensation often reaching $80,000 to $111,000 including bonus. Pay varies by team, location, and experience. The figures below are based on Glassdoor and Salary.com data from 2025 and 2026.

 

Role	Base Salary	Total Comp
Strategy Analyst (Inpoint)	$76K to $93K	$80K to $111K
Strategy Consulting Specialist	$82K to $90K	$84K to $136K
Entry-level analyst (other teams)	$60K to $70K	$65K to $80K
Senior consultant	$110K+	$134K+

 

Aon pay sits below MBB but is competitive within the insurance and risk consulting space, and it comes with strong benefits and clear progression.

 

Aon Case Study Interview Tips

 

Below are my top ten tips for preparing for Aon case study interviews, drawn from coaching thousands of candidates.

 

1. Start preparing early

 

Mastering cases takes time. Many of the skills can't be learned in a day or a week. Ideally, start at least a month or two before your interview to give yourself enough time to learn and practice.

 

2. Learn the right strategies the first time

 

It is far more effective to learn the right strategies upfront than to build bad habits and fix them later. Good case habits take time to form, so build them from the start.

 

3. Practice with a case partner

 

Practicing with a partner is the best way to simulate a real interview. You can work on communication, presentation, and collaboration in ways you simply can't when practicing alone.

 

4. Keep a list of feedback from each case

 

Keep a journal of the feedback you get from each practice case. This lets you spot trends and prioritize. If you keep hearing that your structure needs work, that becomes your top focus.

 

5. Focus on improving one thing at a time

 

After a few practice cases you'll have a long list of improvement areas. Pick one thing to nail before each case. This works far better than trying to fix everything at once.

 

6. Sense check your numbers

 

Missing or adding a zero is the most common math mistake. Do a quick sense check after each calculation to confirm the order of magnitude. If you multiply 115 million by 22, expect billions, since 100 million times 20 is 2 billion.

 

7. Ask clarifying questions if needed

 

You will not be penalized for asking. If a term is unfamiliar, ask for the definition, and if you missed a number, ask the interviewer to repeat it. Clarity makes the case easier to solve.

 

8. Structure your approach before doing any math

 

Lay out your approach before calculating so the interviewer can follow you. A clear structure helps you avoid dead ends and unnecessary work.

 

9. Talk through your calculations out loud

 

Speaking through your math lowers your error rate and lets the interviewer follow along. If you get stuck, they can only help if they can hear what you are doing.

 

10. Be coachable and easy to work with

 

At the end, the interviewer asks: would I want to work with this person? Take their suggestions, and when they challenge you, explain your reasoning politely while acknowledging their point.
