Charles River Associates case interviews test how well you solve economic and data-driven business problems. CRA is an economic consulting firm, so its cases lean on antitrust, litigation, finance, and life sciences questions far more than typical strategy cases do. To land an offer, you will need to pass every single case.

 

If you have an interview coming up, this guide has you covered. As a former Bain Manager and interviewer, I have helped thousands of candidates prepare for cases at firms like CRA. Below is everything you need to crush your Charles River Associates case interview.

 

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 Changed in 2026?

 

This guide was expanded in 2026 to reflect how Charles River Associates actually interviews. We added a full breakdown of CRA's economic consulting focus, how its data-driven cases differ from strategy cases, real CRA case examples, an updated interview process, and current 2026 salary figures.

 

What Is Charles River Associates?

 

Charles River Associates (CRA) is a global economic consulting firm founded in 1965 and headquartered in Boston. The firm provides economic, financial, and management consulting to law firms, corporations, accounting firms, and governments. It is publicly traded on the Nasdaq under the ticker CRAI.

 

CRA has grown from a single office in 1965 to more than 20 offices worldwide. The firm employs roughly 1,600 people, including over 1,000 consultants, with staff from more than 70 countries.

 

Much of CRA's work supports high-stakes legal and regulatory matters. Its experts are frequently hired to provide analysis and expert testimony in antitrust cases, litigation, and disputes over financial damages.

 

What Does Charles River Associates Do?

 

Charles River Associates works across two broad areas: economic litigation and management consulting. Its consultants build economic and financial models, analyze large datasets, and present findings that hold up in court and in front of regulators.

 

CRA's main practice areas include:

 

• Antitrust and competition economics

 

• Litigation support and expert testimony, including damages analysis

 

• Finance and financial economics

 

• Forensic services, such as forensic accounting, eDiscovery, and cybersecurity

 

• Life sciences, including pharmaceutical and healthcare work

 

• Labor and employment economics

 

• Energy and management consulting

 

Knowing which practice area you are interviewing for matters. A life sciences case looks very different from an antitrust or finance case, so research the group before you start preparing.

 

How Are Charles River Associates Cases Different From Other Case Interviews?

 

Charles River Associates cases are more data-driven and economics-focused than the strategy cases used at firms like McKinsey, BCG, and Bain. Instead of only brainstorming a framework, you are often asked what data you would need, how you would analyze it, and what that data would prove.

 

A classic CRA-style question is: two airlines want to merge, so how would you approach it, what data would you need, why would you need it, and what problems might you find with that data? This tests economic reasoning and judgment about data, not just structure.

 

There are four main ways CRA cases differ from typical strategy cases:

 

• They are data-driven. You are judged on how you would source and analyze data, not only on your framework.

 

• They have an economic and legal flavor. Topics like antitrust, damages, market definition, and pricing come up often.

 

• They sometimes expect specific answers. Candidates report that CRA cases feel less open-ended, as if there is a correct analytical path.

 

• They rely heavily on quick math. Estimation, market sizing, and the occasional brain teaser are common.

 

CRA cases are a form of economic consulting case interview, which rewards analytical depth and comfort with numbers. Expect quantitative estimation, market sizing, and sometimes a brain teaser or two.

 

What Is a Charles River Associates Case Interview?

 

A Charles River Associates case interview is a 30 to 45 minute exercise where you and the interviewer work together to solve a business or economic problem. CRA uses cases to see how you would handle the analytical, data-heavy work the firm does for clients.

 

These problems are drawn from the kind of work CRA actually does. For example:

 

• How much did a company lose because of a competitor's patent infringement?

 

• Should a pharmaceutical company acquire a smaller drugmaker?

 

• How would a proposed merger affect competition in a market?

 

• What is the size of a particular market or product category?

 

Like most consulting firms, CRA condenses a months-long project into a short exercise. Many CRA cases are based on real engagements its interviewers have worked on.

 

CRA cases can cover many industries, including energy, life sciences, healthcare, financial services, technology, and consumer products. No specialized knowledge is required for entry-level roles, though a strong grounding in economics, statistics, or finance helps.

 

Nailing your CRA case interviews is critical to getting a job offer. You will need to pass every single one of them.

 

What Is the Charles River Associates Interview Process?

 

Charles River Associates typically runs two rounds of interviews. You will face a mix of behavioral questions, case interviews, and for some candidates, an online assessment and a group case interview.

 

Some candidates are asked to take a numerical, writing, or critical thinking assessment before or between rounds. The first round is often a 30 to 45 minute virtual interview with one or two interviewers, mixing behavioral questions and a short case.

 

CRA behavioral questions ask you to describe a past experience that shows a specific skill. Examples include:

 

• Tell me about a time you resolved a conflict

 

• Give an example of when you used data to solve a problem

 

• Tell me about a time it was difficult to be honest

 

The final round is usually a half-day of three to five interviews with senior staff. It mixes more cases, behavioral questions, and sometimes a group case interview with other candidates.

 

Here is what the process generally looks like:

 

Stage	What to Expect
Application	Resume and cover letter submission
Online assessment (some roles)	A numerical, writing, or critical thinking test
First round	One 30 to 45 minute interview with 1 to 2 interviewers, mixing behavioral questions and a short case
Final round	A half-day of 3 to 5 interviews with senior staff, including cases, behavioral questions, and sometimes a group case

 

The exact process varies by office, practice area, and role. PhD and advanced degree candidates often go through a slightly different track, since CRA recruits heavily from doctoral programs.

 

CRA weighs fit as heavily as analytics, so prepare your stories as carefully as your cases. My Fit Interview Course walks you through 98% of consulting fit questions if you want a head start.

 

What Does a Charles River Associates Case Interview Assess?

 

Charles River Associates case 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 in a single 30 to 45 minute case.

 

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 data and identify the most important points?

 

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

 

Analytical problem solving: consultants work with huge amounts of data to build recommendations.

 

• Can you read and interpret data well?

 

• Can you do math computations smoothly and accurately?

 

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

 

Business acumen: a strong business instinct helps consultants make the right calls.

 

• Do you understand fundamental business and economic concepts?

 

• Do your conclusions make sense from a business perspective?

 

Communication skills: consultants need to work with teammates and clients effectively.

 

• Can you communicate in a clear, concise way?

 

• Are you articulate in what you are saying?

 

Personality and cultural fit: consultants spend a lot of time working closely in small teams.

 

• Are you coachable and easy to work with?

 

• Are you pleasant to be around?

 

Being able to judge all five qualities in a short case is what makes CRA case interviews so effective.

 

How Do You Solve a Charles River Associates Case Interview?

 

There are six steps to solving a Charles River Associates case interview: understand the case, structure the problem, kick off the case, solve quantitative problems, answer qualitative questions, and deliver a recommendation.

 

1. Understand the case

 

Your CRA case interview will begin 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.

 

Do not be afraid to ask clarifying questions if something is unclear. 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.

 

2. Structure the problem

 

The next step is to develop a framework to structure the case. Strong, tailored case interview frameworks make the rest of the case far easier to solve.

 

Before you build your framework, it is fine to ask the interviewer for a minute to collect your thoughts.

 

Ideally, your framework should be as MECE as possible. MECE means mutually exclusive and collectively exhaustive, so each element has no overlap and the elements together cover every important issue.

 

Once you have your major areas, walk the interviewer through your framework. They may ask a few questions or give feedback.

 

3. Kick off the case

 

Once you finish your framework, you will start digging into different areas to solve the case. How this starts depends on whether the case is candidate-led or interviewer-led.

 

In a candidate-led case, you propose which area to investigate first and give a reason for your choice. There is generally no right or wrong area to start with.

 

In an interviewer-led case, the interviewer tells you where to start or gives you a question to answer. CRA cases are generally interviewer-led, though you may occasionally get a candidate-led case.

 

4. Solve quantitative problems

 

Your CRA case will almost certainly have a quantitative element. You may calculate a profitability or financial metric, estimate the size of a market, or estimate another figure.

 

The key is to lay out a structure with the interviewer before doing any math. Once they approve your approach, the rest is simple execution. When doing case interview math, talk through every step out loud so the interviewer can follow you.

 

Once you have an answer, explain how it affects the recommendation you are forming.

 

5. Answer qualitative questions

 

Your CRA case will also have qualitative parts. You may be asked to brainstorm ideas or 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 and then list 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?

 

6. Deliver a recommendation

 

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

 

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

 

What Are Some Charles River Associates Case Interview Examples?

 

Charles River Associates does not publish official case examples. Based on candidate reports, CRA cases tend to be data-heavy and often touch antitrust, litigation, life sciences, or finance.

 

Here are real CRA-style cases that candidates have reported:

 

• Market sizing: How many new golf balls are used in the United States each year?

 

• Antitrust and data: Two airlines want to merge. What data would you need, and what issues might that data have?

 

• Life sciences: A pharmaceutical company is deciding whether to acquire or develop a drug for a specific condition. Should it?

 

• Revenue growth: A large consumer products company wants to grow sales. How would you help?

 

To prepare, practice the common case types you might face. Each one below links to a full walkthrough.

 

• Market entry case: assesses whether to enter a new market or launch a new product. Example: a tech startup is considering entering the European market with a new mobile app. How would you assess the feasibility and potential challenges?
  
  
• Profitability case: focuses on improving a company's profits. Example: a manufacturing company is seeing declining profits. What is causing it, and how would you fix it?
  
  
• Mergers and acquisitions case: evaluates the benefits and risks of a deal. Example: a pharmaceutical company is weighing the acquisition of a biotech startup. How would you assess the fit, synergies, risks, and financials?
  
  
• Growth strategy case: develops strategies to grow the business. Example: a retail chain wants to expand its market share. What strategy would you recommend, given consumer trends and competition?
  
  
• Pricing case: sets or optimizes a pricing strategy. Example: a software company is launching a subscription service. How would you set the price to grow revenue and adoption?
  
  
• Operations case: improves operational processes to cut costs and delays. Example: a logistics company is facing supply chain delays. How would you find the bottlenecks and fix them?
  
  
• Product launch case: builds a plan to launch a new product. Example: a consumer electronics company is about to release a new smartphone. How would you build a launch plan that lands well?

 

Practicing these case types is the fastest way to get comfortable. My Case Interview Course teaches a method for building tailored frameworks for any of them in as little as 7 days.

 

How Much Does Charles River Associates Pay?

 

Charles River Associates pays first-year analysts and associates a base salary of roughly $91,000 to $95,000, based on the firm's 2026 job postings. Including bonus, median analyst total compensation lands near $97,000 according to Levels.fyi.

 

Pay rises quickly with degree level, practice group, and experience:

 

Role	Base Salary (2026)
Analyst or Associate (Bachelor's or Master's)	$91,000 to $95,000
Forensic Services Associate	$100,000 to $120,000
Senior Associate (PhD or ABD, economics)	$175,000 to $220,000

 

PhD economists usually enter at the senior associate level, with base salaries well above $175,000 according to CRA's 2026 postings. That is one reason CRA is a popular landing spot for advanced degree holders.

 

Compensation also varies by city. Higher cost-of-living offices like New York and Boston tend to pay at the top of these ranges.

 

How Hard Is It to Get Into Charles River Associates?

 

Getting into Charles River Associates is hard. Popular roles draw hundreds to thousands of applicants, and the firm hires candidates with strong quantitative backgrounds and top academic records.

 

CRA recruits heavily from economics, finance, statistics, mathematics, accounting, and computer science backgrounds. It also hires many PhD and advanced degree holders, especially in its economic litigation and life sciences groups.

 

The good news is that CRA's process rewards preparation. Because its cases follow a more analytical, data-driven path, candidates who practice economic reasoning and quantitative problems can stand out.

 

Make sure to research your specific practice area, network with current consultants, and give yourself at least a month or two to prepare.

 

How Do You Prepare for Charles River Associates Case Interviews?

 

There are seven steps to preparing for Charles River Associates case interviews: learn what a case is, learn the right strategies, practice a few cases alone, practice with a partner, practice with a consultant, work on your weak spots, and stay sharp.

 

1. Understand what a case interview is

 

The first step is to understand exactly what case interviews are. Once you are familiar with them, learn what a great CRA case performance looks like, which makes the next step go faster.

 

Before moving on, you should know:

 

• The overall objective of a case interview

 

• The structure and flow of a case interview

 

• The types of questions you could be asked

 

• What a great case interview performance looks like

 

2. Learn the right strategies

 

Now that you have the background, learn the right strategies so you build good habits from the start. It is much more effective to learn good strategies the first time than to fix bad ones later.

 

The fastest way to learn these strategies is to go through our Case Interview Course. If you prefer reading case interview prep books, the three I recommend are:

 

• Hacking the Case Interview

 

• The Ultimate Case Interview Workbook

 

• Case Interview Secrets

 

Hacking the Case Interview gives you exactly what to do and say in every step of a case. It is concise and straight to the point, so it is the best first book for beginners.

 

Case Interview Secrets teaches core ideas like the issue tree, drill-down analysis, and a hypothesis-driven approach through stories. If you have read the first book, this one gives you a second author's perspective.

 

Case in Point offers many specific frameworks, though most are too complex for a real case. If you have time, it can be worth a quick skim.

 

At a minimum, read one of the first two books. If you have time, read both to get strategies from two authors.

 

3. Practice 3 to 5 cases by yourself

 

Once you know the strategies, start practicing. It is usually better to practice with a partner, but for your first 3 to 5 cases I recommend working by yourself.

 

There are three reasons for this:

 

• You get the hang of the structure and format faster without waiting on a partner

 

• You can practice many parts, like building frameworks and solving math, on your own

 

• As a beginner, you may struggle to find a partner or to give good feedback yourself

 

4. Practice 5 to 10 cases with a partner

 

Next, practice with a partner. This is the best way to simulate a real case, and some skills only improve with live practice.

 

When you case with a partner, leave enough time afterward for feedback. For a case of 30 to 40 minutes, spend at least 15 to 20 minutes on feedback, since that is where most of your improvement comes from.

 

Do not move on until you have done at least 5 to 10 cases and feel comfortable.

 

5. Practice with a former or current consultant

 

At this point, ask former or current consultants to give you a practice case. They know exactly how to run cases and give feedback, so you will catch issues your earlier partners missed.

 

If you feel you are plateauing with your partner, that is a sign to do a mock with a consultant. You can find them among friends, classmates, colleagues, recruiting contacts, and your wider LinkedIn network.

 

If you do not have access to former consultants, Case Interview Coaching pairs you with experienced interviewers who give detailed, actionable feedback.

 

6. Work on your improvement areas

 

Now strengthen the weak spots you have collected. Common ones include:

 

• Creating a more complete and mutually exclusive framework

 

• Doing math calculations faster and more smoothly

 

• Adding more structure to your qualitative answers

 

• Leading the case more proactively

 

• Delivering a more concise recommendation

 

Focus on one thing at a time, which is far more effective than trying to fix everything at once. Some areas, like math, are better practiced alone, while others, like leading the case, are better with a partner.

 

7. Stay sharp

 

If you have made it this far, congratulations. The key now is to avoid burning yourself out with too many cases.

 

Each case makes you a little better, but too many can cause case fatigue right before your interview. At the same time, going weeks without a case makes you rusty.

 

Once you have reached case mastery, do no more than two cases per week in the lead-up to your interview. This keeps you sharp without the fatigue.

 

What Are the Best Charles River Associates Case Interview Tips?

 

Below are my top ten tips for Charles River Associates case interviews.

 

1. Start preparing early

 

Mastering CRA cases takes time, and most skills cannot be learned in a day or a week. Ideally, start at least a month or two before your interview so you have time to learn and practice.

 

2. Learn the right strategies the first time

 

It is much more effective to learn good strategies up front than to fix bad habits later. Good habits take time to build, so start them from day one.

 

3. Practice with a case partner

 

Practicing with a partner is the best way to simulate a real CRA case. It lets you work on communication, presentation, and collaboration in a way solo practice cannot.

 

4. Sense check your numbers

 

Missing or adding extra zeroes is the most common math mistake. Do a quick sense check after each calculation to confirm your answer is the right order of magnitude.

 

For example, if you multiply 115 million by 22, expect an answer in the billions, since 100 million times 20 is 2 billion.

 

5. Predict the interviewer's next question

 

A great way to stand out is to answer follow-up questions before they are asked. After each answer, think about what the interviewer might ask next and address it right away.

 

6. Have a firm recommendation

 

Do not flip back and forth between two answers. Take a firm stance instead. There is no single right recommendation, so as long as yours is backed by data and evidence, it will be accepted.

 

7. Be coachable and easy to work with

 

You need to show you can solve the case and that you would be a good teammate. At the end, the interviewer asks themselves whether they would want to work with you.

 

When the interviewer offers guidance, take it. When they challenge your answer, calmly give your reasoning while acknowledging their point.

 

8. Use a hypothesis-driven approach

 

Throughout the case, hold a hypothesis about the answer. A hypothesis-driven approach is just an educated guess that you keep refining as you gather more data.

 

This has two benefits. It keeps you focused on the most relevant areas, and by the time you are asked for a recommendation, you already have a refined answer ready.

 

9. Be 80/20

 

You have limited time, so you cannot explore every area or answer every question. Focus on the issues that have the biggest impact on your recommendation.

 

The 80/20 principle says 80% of the outcome comes from 20% of the effort. In a case, that means prioritizing the few questions that matter most.

 

10. Be enthusiastic

 

Show enthusiasm during the interview. It makes the case more enjoyable for the interviewer and signals that you are passionate about consulting and the firm.

 

Interviewers want to hire people who love the work and will work hard. Enthusiasm is a strong signal of both.
