The Compass Lexecon interview is a two to three round process that pairs numerical and verbal reasoning tests with motivation questions and an economics case built around a merger, a damages claim, or a market definition problem. This guide breaks down every round, the questions candidates actually report getting, verified pay bands by level, and the prep plan that separates offers from rejections.

Key Takeaways

 

Compass Lexecon interviews test applied microeconomics and econometrics rather than business judgment, and most candidates move from application to decision in under a month.

 

• Most processes run a reasoning test, a motivation-heavy screen, and a case round with economists, though the sequence shifts by office and practice

 

• Glassdoor puts the average hiring process at 27 days across 273 candidate reports

 

• Cases center on merger review, damages estimation, and market definition, not profitability trees or market entry

 

• Analysts report $80,000 to $112,000 annually on Glassdoor, while senior economists report $140,000 to $253,000

 

• Every application requires a cover letter, resume, transcript, and writing sample, so your written work is judged before you ever interview

 

What Is the Compass Lexecon Interview Process?

 

The Compass Lexecon interview process typically runs two to three rounds over roughly four weeks. Most candidates complete numerical and verbal reasoning tests, a screening interview covering motivation and background, and a final round of one-on-one interviews with analysts, economists, and senior staff that includes an economics case study.

 

1. Application: submit a cover letter, resume, transcripts, and writing sample
   
   
2. Online assessment: a timed numerical reasoning test plus a verbal or abstract reasoning test
   
   
3. Screening interview: a 30 to 60 minute conversation with an analyst or economist about your background and motivation
   
   
4. Final round: two to four back-to-back interviews with economists and senior staff, at least one of which is a case
   
   
5. Decision: an offer or rejection, typically within a week or two of the final round

 

The order is not fixed. Candidates in Milan report a single 60 minute interview split evenly between motivation questions and a case, while candidates in Madrid report a reasoning test followed by a two-person panel and then a separate interview with the prospective team lead.

 

That variation is the single most important thing to understand before you prepare. Your invitation email is the authority on your specific format, and the recruiter will tell you what to expect if you ask.

 

What Does Compass Lexecon Do and Why Does It Matter for Your Interview?

 

Compass Lexecon is an economic consulting firm that provides expert economic analysis for antitrust cases, regulatory proceedings, and commercial disputes. It was founded in 1977, is headquartered in Chicago, and operates as a subsidiary of FTI Consulting.

 

The firm reports more than 600 professionals across 23 offices worldwide. Its clients are law firms, corporations, regulators, and government agencies rather than the CEOs and boards that hire management consultants.

 

That client base changes what interviewers look for. You are being assessed on whether you can produce analysis that survives cross-examination in a courtroom, not on whether you can pitch a growth strategy.

 

The credentials matter for your motivation answer. Compass Lexecon has been ranked an "Elite" competition economics firm by Global Competition Review for nineteen consecutive years as of the 2026 GCR 100. During that research window the firm advised on the FTC v. Meta antitrust suit, the $69 billion Microsoft and Activision merger, and the $34 billion Bunge and Viterra deal.

 

Knowing two or three of those matters by name is the cheapest credibility you can buy. Candidates who can discuss the economic argument in a real Compass Lexecon case immediately separate themselves from those who read the homepage an hour before the call.

 

What Should You Submit With Your Compass Lexecon Application?

 

Compass Lexecon's own recruiting brochure lists four documents to submit with your application: a cover letter, a resume, transcripts, and a writing sample. All four are expected, and university postings for the analyst role repeat the same list.

 

The writing sample is the requirement candidates most often fumble. Interviewers use it as evidence that you can explain an empirical result to a reader who is smart but not an economist, which is exactly what the job requires.

 

Pick a thesis chapter, an econometrics term paper, or a policy memo where you owned the analysis. Avoid group projects where your contribution is invisible and avoid anything longer than about 20 pages.

 

Your consulting resume needs to prove technical ownership, not exposure. "Ran regressions in Stata" is weak, while "estimated the price effect of a 2019 merger using a difference-in-differences model on 40,000 transaction records" is a conversation starter.

 

If you want a second set of eyes before you submit, my resume review and editing service gives you unlimited revisions with a 24-hour turnaround.

 

Your cover letter should name the practice area you want. Antitrust and competition, international arbitration, securities and financial markets, and valuation all recruit separately, and generic letters read as generic interest.

 

Referrals help here too. Glassdoor reports that 68% of Compass Lexecon candidates applied online, 24% came through campus recruiting, and 8% arrived through an employee referral, which means consulting referrals are rarer and therefore more distinguishing than at large management consulting firms.

 

What Happens in the Compass Lexecon Online Assessment?

 

Most Compass Lexecon candidates take two timed tests early in the process: a numerical reasoning test and a verbal or abstract reasoning test. Candidates consistently describe the numerical section as GMAT style and roughly 30 minutes long, with time pressure rather than difficulty as the real constraint.

 

The verbal section is closer to GRE reading comprehension and is straightforward for native English speakers. Some candidates also report three or four logic-based questions mixed into the quantitative section.

 

Glassdoor candidate reports show skills tests appearing in 14% of Compass Lexecon interview processes and personality or aptitude assessments in another 10%. That means the tests are common but not universal, and their presence often depends on your office and role.

 

Practicing case interview math under a timer is the single best preparation for this stage. The arithmetic itself is not hard, but candidates who compute percentages, ratios, and growth rates slowly run out of clock and leave questions blank.

 

What Fit and Motivation Questions Does Compass Lexecon Ask?

 

Motivation questions carry more weight at Compass Lexecon than at most firms. One candidate in Milan described a 60 minute interview where the first half was entirely motivational and centered on whether they actually understood what the firm does.

 

Here are the questions candidates report most often:

 

• Why economic consulting rather than management consulting, academia, or finance

 

• Why Compass Lexecon specifically

 

• What is competition economics, and what do we actually do here

 

• Walk me through your resume

 

• Tell me about a time you used data to answer a hard question

 

• Which econometric methods and software are you comfortable with

 

• Explain the theory behind your thesis or research paper

 

That last question is where PhD and master's candidates get tested hardest. One candidate reported a partner with a Harvard economics doctorate pressing them on the theory behind their banking and competition research for most of the interview.

 

A strong "Why Compass Lexecon" answer has three parts: a specific practice area, a real matter the firm worked on, and a link to your own quantitative background. Here is an example.

 

Sample answer: "I want to work on merger control, and Compass Lexecon is where the largest merger cases actually get argued. Reading the economic submissions in the Microsoft and Activision matter is what convinced me that competitive effects analysis is the work I want to do. My thesis estimated diversion between competing grocery chains, so market definition is already the problem I have spent two years thinking about."

 

Notice that the answer never praises the firm's culture. Vague enthusiasm reads as filler to an interviewer who has heard it 200 times, while a named case and a matching skill read as genuine interest.

 

If your behavioral answers still feel unstructured, my fit interview course covers 98% of the questions you will get in a few hours.

 

What Does a Compass Lexecon Case Interview Look Like?

 

A Compass Lexecon case is an applied economics problem, not a business strategy problem. You are typically given a scenario, asked how you would approach the analysis, and pushed on your assumptions and your data.

 

Three archetypes come up repeatedly in candidate reports.

 

Merger review. You evaluate a proposed acquisition from a competition authority's perspective. One London candidate reported analyzing a proposed merger across two hour-long technical interviews with managing directors.

 

Your job is to define the relevant product and geographic market, measure concentration, assess whether the merging parties are close substitutes, weigh any efficiency claims, and recommend clearance, remedies, or a block.

 

Damages estimation. You calculate the harm caused by conduct such as price fixing or predatory pricing. One candidate was asked to develop an approach for quantifying the damage caused by a dominant firm's predatory pricing in a specific European market.

 

The core move is building a but-for benchmark: what would the price have been absent the conduct. Everything else is controlling for alternative explanations so the number you land on survives challenge.

 

Microeconomic theory. Some offices skip the applied case and test fundamentals directly. One candidate reported a case built on the theory of the firm and warned that interviewers look for conceptual precision rather than a clever answer.

 

Others report broader economics questions, such as how a slowdown in Chinese GDP would affect a Chinese exporter, or how you would value a company using a discounted cash flow model.

 

Some processes add a written component where you read a short case, discuss it, and then write up your recommendation on a computer. Treat the writing as part of the assessment rather than an afterthought, because clear written economics is the actual deliverable of the job.

 

The good news is that the underlying habits transfer. Structuring a problem into clean buckets, running clean arithmetic, and delivering a crisp recommendation are the same skills the standard economic consulting case interview rewards, and my case interview course builds them in about seven days.

 

How Is a Compass Lexecon Case Different From a Management Consulting Case?

 

The difference is what gets tested. A management consulting case tests business judgment under uncertainty, while a Compass Lexecon case tests whether your economics is correct and defensible.

 

Dimension	Compass Lexecon case	Management consulting case
Core skill	Applied microeconomics and econometrics	Business judgment and structured problem solving
Typical scenario	Merger review, damages, market definition	Market entry, profitability decline, acquisition
Data provided	Regression output, price series, statistical tables	Revenue tables, market share charts
Who you advise	A law firm, a regulator, or a court	A CEO or a board
Math involved	Coefficients, standard errors, concentration indices	Back-of-envelope profit and market sizing math
Output	A defensible estimate with stated limitations	A confident recommendation with next steps

 

In my experience at Bain, the strongest case answer was the one that committed to a recommendation and moved. Economic consulting inverts that instinct, because an economist who overclaims gets destroyed on the stand, so naming your assumptions and your error bars is a strength rather than hedging.

 

The habit to keep is structure. The habit to drop is the template, since forcing standard case interview frameworks onto an antitrust problem signals that you have not understood the role.

 

What Technical Concepts Do You Need to Know?

 

You need working fluency in industrial organization and applied econometrics. You do not need to be able to derive results, but you do need to explain what a number means and what would make it wrong.

 

These are the concepts that appear most often in Compass Lexecon interviews:

 

• Market definition: the hypothetical monopolist test and how a small but significant price increase reveals whether a market is drawn correctly

 

• Concentration measures: calculating the Herfindahl-Hirschman Index before and after a merger, and reading the change against regulatory thresholds

 

• Diversion ratios: what share of one firm's lost customers goes to the other party, and why that drives upward pricing pressure

 

• Regression interpretation: coefficients, standard errors, p-values, and R squared, plus what each one does and does not prove

 

• Causal identification: difference-in-differences, instrumental variables, omitted variable bias, and selection bias

 

• Damages logic: but-for benchmarks, overcharge estimation, and pass-through to downstream buyers

 

• Vertical theories: foreclosure, raising rivals' costs, and when a vertical merger actually harms competition

 

• Software fluency: loading data, running a regression, and reading output in Stata, R, or Python

 

Compass Lexecon's own materials describe analyst work as spreadsheet modeling, regression analysis, industry research, and drafting expert reports and government filings. The interview is a preview of that work rather than a proxy for it.

 

How Much Does Compass Lexecon Pay?

 

Based on Glassdoor data from August 2026 covering 472 submitted salaries across 35 job titles, Compass Lexecon pay ranges from roughly $47,000 for interns to $350,000 at the senior vice president level.

 

Role	Reported annual pay	Salaries submitted
Intern	$47,000 to $76,000	13
Analyst	$80,000 to $112,000	172
Senior Analyst	$95,000 to $130,000	125
Economist	$128,000 to $235,000	51
Senior Economist	$140,000 to $253,000	33
Vice President	$202,000 to $296,000	22
Senior Vice President	$228,000 to $350,000	5

PhD economists command a much higher entry point. A Compass Lexecon senior economist listing posted through the American Economic Association's Job Openings for Economists board for the 2025 to 2026 hiring cycle stated a base salary of $250,000 for candidates with a relevant PhD, plus eligibility for a signing bonus and an annual discretionary bonus.

 

That gap between the analyst and economist tracks is the defining feature of the economic consulting career path. Analysts who want the senior economics roles generally leave for a doctorate after two to four years, and Compass Lexecon openly markets its analyst role as preparation for graduate study.

 

How Long Does the Compass Lexecon Hiring Process Take?

 

The average Compass Lexecon hiring process takes 27 days according to 273 Glassdoor interview reports updated in April 2026. Timelines swing widely by role, from an average of 6 days for consultant candidates to 60 days for research analyst internship candidates.

 

Individual experiences vary even more. Candidates report processes running anywhere from about ten days for a Madrid internship offer to several weeks for a full analyst cycle with a reasoning test and multiple rounds.

 

Campus timelines are the ones you can actually plan around. Compass Lexecon runs virtual information sessions for North American analyst and intern candidates and has posted application deadlines in early autumn for the following summer, so undergraduate applications generally close a full academic year before the start date.

 

Glassdoor's stage data shows what a typical process contains. One-on-one interviews appear in 27% of reported processes, phone interviews in 19%, skills tests in 14%, group or panel interviews in 11%, and presentations in 9%.

 

How Do You Prepare for the Compass Lexecon Interview?

 

Four weeks is enough time if you use it on the right things. Here is how I would sequence it for a candidate targeting an analyst or intern role.

 

Tip #1: Rebuild your industrial organization fundamentals first

 

Compass Lexecon cases sit on top of industrial organization theory, so market structure, pricing, market power, and welfare analysis need to be automatic. Spend the first week rereading your undergraduate IO notes rather than doing practice cases.

 

Candidates who tested well on the theory of the firm case reported that interviewers wanted conceptual precision, not creativity. If you cannot explain why a monopolist restricts output in two clean sentences, you are not ready for the applied questions.

 

Tip #2: Get fast at reading regression output

 

You should be able to look at a coefficient table and say what the estimate means, whether it is precisely estimated, and what would bias it, all within about two minutes. Pull three published economics papers and practice reading only their results tables.

 

Add the identification vocabulary as you go. Naming endogeneity, omitted variable bias, or a plausible instrument is what turns a description of a number into an economic argument.

 

Tip #3: Learn three real Compass Lexecon matters in depth

 

The firm publishes its case work openly, so pick three matters and learn the economic argument on both sides. FTC v. Meta, the Microsoft and Activision merger, and Illumina's €5.9 billion acquisition of Grail are all recent and all well documented.

 

This does double duty. It sharpens your motivation answer and gives you a reference point when an interviewer asks how you would approach an unfamiliar merger.

 

Tip #4: Practice writing your recommendation, not just saying it

 

Since some processes ask you to write up your analysis on a computer after discussing the case, set a 45 minute timer and write a one-page economic recommendation on a merger of your choosing. Then cut it by a third.

 

Concision under time is a learnable skill and almost nobody practices it. The candidates who write well are the ones who get staffed on expert reports early.

 

Tip #5: Drill timed arithmetic before the reasoning test

 

The numerical test punishes slow computation more than weak math. Twenty minutes a day of percentage, ratio, and growth rate drills for two weeks will move your score more than any content review.

 

The same drills pay off in the case, where a botched concentration calculation undermines every qualitative point you make afterward.

 

Tip #6: Prepare to defend your own research

 

Whatever is on your resume, assume an economist will ask you to explain the theory behind it and then push back. Rehearse a two minute summary of your thesis or largest project, then rehearse the three hardest follow-up questions you would ask yourself.

 

Candidates applying with a PhD face the sharpest version of this, since the job market paper conversation often is the interview.

 

Tip #7: Run one full mock in the real format

 

In the final week, simulate your actual invitation end to end: reasoning test, motivation questions, case, and any written component. Stamina and time management are what break down on the day, and you only find those gaps by running the whole thing once.

 

Having coached hundreds of candidates one-on-one, the pattern I see most is strong preparation on content paired with zero rehearsal of the format. The full mock fixes that in a single afternoon.

 

What Mistakes Do Compass Lexecon Candidates Make Most?

 

There are four mistakes that account for most rejections at this firm.

 

Preparing with management consulting materials. Profitability trees and market entry structures do not fit an antitrust problem, and reaching for one signals you have not researched the role. This is the most common error among candidates who also recruit for strategy firms.

 

Giving a vague motivation answer. Motivation is weighted heavily and "I like data" fails immediately. Name a practice, a matter, and a skill.

 

Quoting numbers with no caveats. An overcharge estimate or a concentration figure with no stated assumptions is worthless in litigation. State the limitation before the interviewer finds it.

 

Treating the written work as secondary. The writing sample and any in-interview write-up are assessed as seriously as the discussion, because expert reports are the firm's actual product.

 

Compass Lexecon sits in a small cluster of firms that recruit the same profile, alongside Analysis Group, NERA, Cornerstone Research, Charles River Associates, and the Brattle Group. Applying to three or four of them in the same cycle is normal and gives your preparation more than one shot at paying off.

 

The Compass Lexecon interview rewards candidates who treat it as an economics assessment rather than a consulting assessment, so build your preparation around industrial organization, regression interpretation, and a motivation answer anchored in a real case the firm actually argued. If you do one thing this week, learn three Compass Lexecon matters well enough to explain the economic argument on both sides.

 

Frequently Asked Questions

 

How long is the Compass Lexecon interview process?

 

Glassdoor data from August 2026 puts the average Compass Lexecon hiring process at 27 days across 273 candidate reports. Speed varies enormously by role. Consultant candidates reported an average of 6 days, while research analyst internship candidates reported an average of 60 days. Campus recruiting cycles tend to move faster than off-cycle experienced hire searches.

 

Does Compass Lexecon require a PhD?

 

No. Compass Lexecon states that analysts join after a bachelor's or master's degree in a quantitative field. A PhD in economics is required only for the economist and senior economist tracks, or you can reach those levels through several years of experience in competition economics. Analysts make up the largest share of candidate interview reports on Glassdoor.

 

What kind of case study does Compass Lexecon give?

 

Compass Lexecon cases are applied economics problems rather than business strategy problems. The two most common archetypes candidates report are merger review, where you define the relevant market and assess competitive effects, and damages estimation, where you build a but-for benchmark and calculate an overcharge. Some offices also give microeconomic theory questions about pricing, market power, and the theory of the firm.

 

How much does a Compass Lexecon analyst make?

 

Based on Glassdoor data from August 2026, Compass Lexecon analysts report annual pay between $80,000 and $112,000 across 172 submitted salaries. Senior analysts report $95,000 to $130,000. Pay varies significantly by office, with New York and Washington reporting higher figures than smaller US locations.

 

Is the Compass Lexecon interview hard?

 

Glassdoor rates the Compass Lexecon interview as average difficulty with a very positive candidate experience across 273 reports. The difficulty is technical rather than adversarial. Candidates consistently describe interviewers as friendly and willing to guide their thinking, but the economics content is real and you cannot bluff your way through a regression table or a market definition question.

 

What should you submit with a Compass Lexecon application?

 

Compass Lexecon asks applicants to submit a cover letter, resume, transcripts, and a writing sample. The writing sample is the requirement most candidates underestimate. A thesis chapter, a research paper, or a policy memo that shows you can explain an empirical result to a non-technical reader is the strongest choice.
