Pulsepoint Sepsis Test: Pricing a rapid blood test for hospital labs

A pricing case with limited information, the kind of problem CRA says its case interview uses, and close to the pricing-model case an antitrust intern described. CRA has no published sample case and no separate Management Advisory interview guide, so this is the closest honest practice, set in life sciences. The full version is MedSuite Technologies, a library pricing case on a healthcare product, not a CRA case. Charles River Associates (opens in a new tab), read

Step 1: Read the case

Pulsepoint, a medical diagnostics company, has built a rapid blood test that spots sepsis in under an hour. Hospitals today send blood to an outside lab. Pulsepoint's CEO asks what it should charge per test at launch in the US. How would you work it out?

Step 2: Ask clarifying questions

Open a question to hear the interviewer's answer.

Who buys the test and how is it used?

Interviewer: Hospital labs buy it and run it in the emergency department on patients who might have sepsis. It replaces the outside lab test.

What does the hospital pay for the outside lab test today?

Interviewer: About forty dollars per test, and results take most of a day.

What does it cost Pulsepoint to make and ship one test?

Interviewer: About twelve dollars. Fixed costs are covered by other products, so ignore them.

Does the test save the hospital money, and where?

Interviewer: Yes. In about one in ten tested patients the result arrives a day earlier than it would have, which saves one day in intensive care, worth about fifteen hundred dollars.

What is the goal, and are there competitors?

Interviewer: Maximise profit per test over the first year without losing the hospital's adoption. One rival has a slower rapid test; it is not listed in the data you have so far.

Step 3: Structure your answer

Take two minutes. Say how you would set a launch price: what you need to know, in what order, and what the answer would look like.

2:00
Show what a strong structure covers
  • Plays back the goal: a price per test, for hospital labs in the US, to maximise first-year profit while keeping adoption.
  • Sets the floor and the ceiling: the cost to make a test is the floor, and the value to the hospital is the ceiling.
  • Values the test for the hospital: the outside test it replaces, plus the intensive care days saved, per test.
  • Looks at alternatives and competitors: the outside lab price and the rival rapid test decide how much of the value Pulsepoint can keep.
  • Thinks about demand: how many tests a hospital runs, how sensitive it is to price, and what a pilot price could teach.
  • Names what would change the answer: the share of patients where the test saves a day, contract length and how fast hospitals adopt.

Step 4: The interviewer's next question

One in ten tested patients saves one intensive care day worth fifteen hundred dollars. The test replaces a forty dollar outside test and costs twelve dollars to make. What is the most a hospital should pay per test, and what price would you propose?

Show what a strong answer does

Value per test from the saved day is 10% × 1,500 = 150 dollars; add the forty dollars it replaces and the ceiling is about 190 dollars, against a floor of 12. A strong answer does not price at cost plus a margin: it proposes a price well below the ceiling, around 100 dollars, so the hospital keeps a clear gain, says what it would test next (the one in ten, the rival's price) and states the answer in one line.

Worked: The pricing-model case (antitrust intern interview, reported), in The reported steps: reason aloud, use statistics, ground it in economics

An antitrust intern wrote that a senior staff member gave him a hypothetical competition case about building a pricing model, where statistics and econometrics were central and the reasoning mattered more than the exact answer. CRA publishes no figures, so this walk-through follows only the steps the account describes. Read the official case (opens in a new tab) (read )

How you might work it is ours, not Charles River Associates' answer key.

  1. Say what is being priced and who reacts

    Restate the product, the market and who could respond to a price change (buyers, rivals). In competition work the interviewer wants to see you think about how others react, not only about the client's costs.

  2. Name the data you would want

    Prices and quantities over time and across products or regions, costs and any event that moved prices. Say what you would ask for if you could not have it.

  3. Describe the statistical model in plain words

    Explain that you would estimate how quantity changes when price changes while holding other drivers fixed, for example with a regression, and say which controls you would add and why.

  4. Tie the result to an economic fact

    Read the estimate in business terms: how sensitive buyers are to price, and what that implies for the client's best price or for a harm claim. The reported advice is that sound logic backed by economic facts matters more than the exact answer.

  5. Show the math and name the limit

    Do the arithmetic aloud, state the assumption most likely to be wrong, and say how the answer moves if it changes. CRA's page asks you to show your math.

Method: Candidates report; not on the firm's pages

The Charles River Associates interview process, and what trains each step

  1. Apply to a practice and an office

    CRA asks for a one-page resume and a cover letter that says why you want consulting and CRA; for multi-practice or multi-office roles, name the practices and offices you would consider. A Talent Acquisition team member emails you if your background matches the role.

    Source: Charles River Associates careers (opens in a new tab), checked

    Train it with:

  2. Assessment, in some roles

    CRA says assessments may cover numeracy, writing and critical thinking, and are usually timed, so track your start and finish times. Its pages do not say which roles get one.

    Source: Charles River Associates careers (opens in a new tab), checked

    Train it with:

  3. First round: on campus or virtual

    CRA says the first round is on campus or virtual and that the process varies by office and practice group. A Finance analyst wrote on CRA's site that hers was thirty minutes with two staff, checking skills, interest in economic consulting and practice fit.

    Source: Charles River Associates careers (opens in a new tab), checked

    Train it with:

  4. Experience interview and case interview

    CRA describes an experience interview (your experience, skills and goals, with prompts such as "Tell me about a time when you have...") and a case interview that tests how you approach a problem with limited information: there is usually no single correct answer, so explain your reasoning and show your math.

    Train it with:

  5. Second round in an office

    CRA says second-round interviews generally take place in one of its offices, where you meet several consultants and colleagues over coffee or lunch. A Finance analyst described four back-to-back interviews and a lunch with junior staff; an antitrust intern described four sessions of about thirty minutes. CRA gives no offer timeline; the Finance analyst says an interviewer phoned her with the offer, then a formal letter followed.

11 Charles River Associates-style interview questions

In our words, not CRA's, grouped by the interview parts CRA names: the experience interview, the case on limited information, the Management Advisory sectors (Life Sciences and Energy) and the timed assessment, with what a strong answer does.

Experience interview

CRA: questions about your experience, skills and career goals, including prompts such as "Tell me about a time when you have...".

  1. Why economic consulting, and why CRA rather than a strategy firm or a bank?

    What a strong answer does: Names what CRA's practice does (data and economics applied to a client's question), one project of yours that used the same skills, and how the work differs from finance or strategy, in under a minute.

    Practice it:Fit interview practice

  2. Walk me through a course project or job where you worked with data and what you concluded.

    What a strong answer does: Gives the question, the method, one number and the conclusion, then ties the method to the practice's work. An antitrust intern was asked how his classes and research linked to the practice.

    Practice it:Fit interview practice

  3. Tell me about a time you had to explain a technical result to someone who did not want the detail.

    What a strong answer does: Picks a moment of choice, says what was cut and why, and ends with what the listener did next.

    Practice it:Fit interview practice

Case interview: limited information

CRA: there is usually no single correct answer, so explain your reasoning and show your math.

  1. A manufacturer of hospital equipment asks how to price a new product with no direct competitor. How do you set the price?

    What a strong answer does: Sets a floor (cost) and a ceiling (value to the buyer against what it replaces), then shares the value, asks about rivals and says how a pilot would test it.

    Practice it:MedSuite Technologies Hospital Software Pricing

  2. You have prices and quantities for a product across twenty regions over five years. What would you do to learn how demand reacts to price?

    What a strong answer does: Says it would estimate quantity against price controlling for income, season and other drivers, notes that price and demand can move together for other reasons, and states what it would check.

    Practice it:Case Structure Practice Tool

  3. Two competing suppliers want to merge. What do you look at first?

    What a strong answer does: Defines the market, looks at the combined share and how close the products are, asks whether buyers can switch and whether new entrants would come, then says which fact would change its view.

    Practice it:Case Structure Practice Tool

Management Advisory: Life Sciences and Energy

CRA's services site names Life Sciences and Energy as the sectors for its management consulting; the jobs page puts these roles under Management Advisory.

  1. A drug maker is deciding the launch price of a specialty medicine. What do you need to know?

    What a strong answer does: Looks at the patients who benefit and what the alternatives cost, who pays and how access works, the cost to make and serve, and the price range that keeps the product used.

    Practice it:MedSuite Technologies Hospital Software Pricing

  2. A utility's fast-charging network lost money after a grid tariff change. How do you find the cause and a fix?

    What a strong answer does: Splits profit into price, volume and cost, isolates the cost that changed (peak power charges), checks which customer segment carries it and proposes pricing or load changes with their effect.

    Practice it:Voltigo FastCharge Turnaround

  3. How big is the US market for home batteries, and how would you decide whether to enter it?

    What a strong answer does: Sizes it from households that want backup or time-of-use savings times adoption and price, cross-checks against installer capacity, then states what the entry decision rests on.

    Practice it:Market Sizing Practice Tool

Timed assessment

CRA: assessments may cover numeracy, writing and critical thinking, and are usually timed.

  1. A price rises from 80 to 92 and quantity falls from 500 to 470. Did revenue go up, and by how much?

    What a strong answer does: Computes 80 × 500 = 40,000 and 92 × 470 = 43,240, so revenue rose by 3,240 or about 8%, and notes demand fell about 6% against a price rise of 15%.

    Practice it:Case Math Practice Tool

  2. A chart shows a firm's share of a market falling from 40% to 30% while the market grows from 100 to 150. Did its sales fall?

    What a strong answer does: Multiplies share by market size for both years (40, then 45), so sales rose, and says why the share alone misleads.

Charles River Associates interview prep questions

How do I prepare for the CRA case interview?

Start with CRA's own page, Prepare to Apply & Interview: it says the case interview tests how you handle limited information, that there is usually no single correct answer, and that you should explain your reasoning and show your math. Then find out which practice you are applying to, because CRA says the process varies by office and practice group: economic consulting practices lean on experience questions and quantitative reasoning, and the Management Advisory roles in Energy and Life Sciences are strategy consulting. On Road to Offer a free account includes 1 full AI-graded case, such as MedSuite Technologies, a pricing case; Corbelworks (pricing) and Dunmore Cargo Bikes (market sizing) are worked cases with a model answer for every step and need no account; case math, chart and market sizing drills cover the numbers. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.

Where can I practice CRA-style case interviews for free?

CRA publishes no practice cases of its own, only interview tips and two past recruiter webinars. On Road to Offer, the sample case on this page (pricing a new hospital test) runs in your browser with no account, and your first full case is free with a free account, no card. Corbelworks (a pricing case) and Dunmore Cargo Bikes (market sizing) are free to read in full with a model answer for every step, no account. None of them is a CRA case; they are general practice cases chosen for the pricing, sizing and energy and life sciences questions CRA's practices work on.

Does CRA run case interviews?

Yes, but the format depends on the practice. CRA's interview page lists an experience interview and a case interview that tests how you approach a problem with limited information. Candidate accounts on CRA's own site describe a pricing-model case with statistics and econometrics in the Antitrust practice and a mix of behavioral questions and case studies in Finance. CRA's careers pages do not describe the Management Advisory interview separately, so ask your recruiter what to expect.

Is CRA a management consulting firm?

Partly. CRA's careers site lists economic practices such as Antitrust & Competition Economics, Finance and Forensic Services next to Energy, Life Sciences and Marakon, and its services site says CRA and its subsidiary Marakon do management consulting, with Life Sciences and Energy as named sectors. The jobs page lists Management Advisory analyst and associate roles. CRA's own application advice says to explain why you want economic consulting and how it differs from finance and strategy consulting, so say which side you are applying to.

What are CRA's practices and which one interviews like a strategy case?

CRA's careers page lists Antitrust & Competition Economics, Energy, Finance, Financial Economics, Forensic Services, Intellectual Property, Labor & Employment, Life Sciences, Marakon, Risk, Investigations & Analytics and Transfer Pricing. The jobs page puts the Energy and Life Sciences strategy roles under Management Advisory. CRA does not say which practice uses which case; expect questions tied to the practice you apply to, which an antitrust intern also wrote.

How many interview rounds does CRA have?

CRA says the first round is on campus or virtual and the second round generally takes place in one of its offices, and that the process varies by office and practice group. A Finance analyst described a thirty-minute first round with two staff, then four back-to-back interviews and a lunch in Boston. An antitrust intern described about two hours in four sessions of about thirty minutes.

Is the CRA case interview candidate-led or interviewer-led?

CRA's pages do not say. The antitrust intern's account describes working through a pricing-model case with a senior staff member while explaining the reasoning. Practise both: offer a short structure first, then answer one directed question at a time with a number.

Does CRA have an online test or assessment?

CRA says assessments may cover numeracy, writing and critical thinking, and are usually timed. It does not say which roles get one or give a sample. Practise quick math, chart reading and a short written summary under a clock; Road to Offer has no CRA test simulator, so the closest practice is the case math and chart drills.

Can I use AI in a CRA interview?

No. CRA's recruiting page says it expects you to turn off all AI applications during virtual and live interviews, to answer honestly if asked about your AI use in the application process, and to use AI only to assist your application materials, not to replace your voice.

Does CRA publish case interview guidance or sample cases?

Not sample cases. It publishes interview tips, a candidate-written FAQ and two recruiter webinars: Acing the Job Interview (17 October 2024) and Case Closed: Demystifying the Case Interview (3 September 2025), whose page says the recruiting team will teach how to approach case-style questions. Neither page contains a worked case, and both dates have passed. Unlike McKinsey, whose sample cases include suggested answers, CRA leaves practice cases to you.

When does CRA recruit interns and graduates?

CRA's FAQ says internship postings typically go up in mid-August and internship recruiting usually ends in March, and that it recruits at several schools in the US and UK. A 2027 graduate Management Advisory posting says resume review begins on 31 August and continues on a rolling basis. Check the posting for your office.

What should I put in a CRA cover letter?

CRA says to explain your interest in the role, consulting and CRA, give examples of your strengths and, for multi-practice or multi-office roles, name the practices and offices you would consider. Its application advice adds that a strong application answers why economic consulting and what in your experience shows you can do the work, and warns against reusing a generic investment banking or strategy consulting letter.
