None of the BCG careers pages we read on November 3, 2026 mention a Potential Test. The tests they describe depend on the office: the Consulting Career Assessment of about 30 to 35 minutes in the US, Canada and Mexico, a 30-minute cognitive test with no tools in Switzerland, Germany and Austria, and numerical or logic tests in London, Australia and New Zealand, and the Nordics. For the arithmetic these tests lean on, Soreno, an AI voice interview practice app for consulting and finance candidates, has free case math drills with no sign-up and full BCG-style mock cases with scored feedback for the interviews after the test.
Updated
BCG's application FAQ says some positions ask for an online assessment and that the process varies by role and location. These cards stick to what each office's careers page says, read November 3, 2026. The online case is a separate test with its own page.
The Consulting Career Assessment, which BCG's pages also call the Consultant Career Assessment.
A virtual cognitive test at the start of the first round.
A numerical assessment between the application and the first interviews.
A logical reasoning test before the first interview round for the Visiting Associate internship.
BCG Mexico's careers page links a five-page FAQ for applicants to its offices, last updated December 2024. It is the most detailed description of the CCA on BCG's sites that we found, so check your own invitation for anything that differs.
Who makes it
BCG says SHL, a third-party assessment platform, designs and administers the CCA, and that it measures the building blocks of cognitive functioning and behavioral traits.
BCG: CCA FAQs (PDF)Is it a test?
BCG says there are no right or wrong answers to the behavioral questions, and that the logic portion looks at your reasoning tendencies. It says there's no need to study in advance.
Tools
Unlike the cognitive test in Switzerland, Germany and Austria, the CCA allows a calculator. The 30 to 35 minutes include the tutorial and practice questions, which BCG encourages you to do.
Pausing
You can pause between sections, though BCG encourages one sitting. You can't retake it if something goes wrong.
Other SHL tests
The CCA is customized to BCG, so another firm's SHL test doesn't replace it. If you applied in the US in the past year and took the CCA then, you don't take it again.
Results
BCG says CCA results are always considered alongside the rest of your application. BCG Unlock adds that a score from the last 12 months is linked to your profile automatically.
BCG Unlock: pre-MBA programBCG doesn't publish sample items for these tests on the pages we read, so these are ours, written for the no-tools, multiple choice style BCG Switzerland describes. Item 1: a client's revenue by region is North $240M at a 15% margin, South $180M at a 25% margin, West $120M at a 30% margin. What is its overall profit margin? Options: A 20.0%, B 21.7%, C 23.3%, D 25.0%.
Item 1, step 1
Profits are $36M, $45M, $36M, so $117M on $540M of revenue.
Item 1, step 2
20% of $540M is $108M. The other $9M is about 1.7% of $540M, so the margin is about 21.7%: option B.
Item 1, trap
Option C gives each region equal weight. North is the biggest region and has the lowest margin, so the true margin sits below the simple average.
Free percent and margin drillsItem 2
A price rises 25% and is later cut 20%. Multiply the factors, 1.25 times 0.8, and the price ends where it started: a 0% change. The tempting answer, 5%, adds percentages taken on different bases.
The same trap with a stock priceItem 3
Each number is the one before doubled, plus one, so the next is 63. Check the rule on every step before you pick: a rule that fits only the first two terms is the usual wrong answer.
Pace
The Nordic test's 80 questions in 30 minutes leave 22.5 seconds each. In our experience, at that pace skipping an item that stalls you costs less than finishing it.
The ones that change how you plan the days after you apply.
US
The CCA invitation arrives 30 to 90 minutes after you submit, and you have 48 hours to finish it.
BCG: US Associate opportunitiesUS MBA
Summer MBA applicants to US, Canada or Mexico offices take the CCA. Anyone who took it in BCG Unlock doesn't take it again.
BCG: US MBA opportunitiesMexico
BCG Mexico says if you can't finish the CCA or the online case in time, tell them and take it in the next recruiting window, which may be several months away.

BCG's pages describe what each test looks at in a line or two. These are their words, by test.
BCG Switzerland's and BCG Germany and Austria's cognitive test, answered without any tools.
The CCA's logic portion, which BCG Mexico's FAQ says looks at your reasoning tendencies.
The CCA's behavioral questions, with no right or wrong answers.
The Nordic logical reasoning test, which BCG says supplements the business case.
BCG Mexico says its assessments test problem-solving, analytical and critical thinking skills, and advanced technical knowledge isn't required.
BCG's US Associate page, in order. Applications for 2027 summer and full-time roles had closed when we read it.
Step 1
You confirm your top two offices when you apply. BCG says not to change them across several applications in the same period.
Step 2
The invitation comes 30 to 90 minutes after you submit, if you applied to the US application.
Step 3
A select group is invited to an online case of about 35 minutes, about two weeks after the deadline. Anyone who took it before isn't asked again.

BCG's FAQ says the number and structure of interviews varies by position and region, virtual or in person.
BCG case interview guideFrom BCG: application FAQs.
Written by us. Do the number items without a calculator, the way BCG Switzerland's test runs, then take the case prompts out loud.
Percentages, growth and margins from small tables.
Sales grew from $80M to $92M. What is the growth rate?
Change over the starting value: 12 over 80 is 15%. Dividing by 92 gives 13.0%, the common slip.
A stock falls 50% and then rises 50%. Where does it end?
Multiply the factors, 0.5 times 1.5, so it ends 25% below where it began. Practice it, see a model answer
A product sells 1,200 units at $45 with a $30 variable cost. What is its contribution?
Contribution per unit is $15, so $18,000 in total. Say the unit figure first, then scale.
A competitor cut prices by 20%. How much more volume does a client need to keep revenue flat if it matches?
Revenue holds when volume rises to 1 over 0.8, a 25% rise. Then ask whether margins can take it. Practice it, see a model answer
The parts BCG names besides numbers.
What is the angle between the clock hands at 3:15?
The hour hand has moved a quarter of the way from 3 to 4, 7.5 degrees, so the answer is 7.5 degrees, not 0. Practice it, see a model answer
All of a client's stores that opened after 2020 are profitable. Store K is profitable. Did it open after 2020?
Can't tell. The rule runs one way only, which is the trap in most verbal and logical items.
How would you check an estimate before you give it?
Test it against a second route and a known benchmark, then say which one you trust more. Practice it, see a model answer
The interviews that follow, in BCG's style.
A grocery chain's profits fell 20%. Where would you look first?
Split profit into revenue and costs, size each move, then pick the branch that explains most of it. Practice it, see a model answer
Why BCG?
Two specific reasons tied to what you saw of BCG's work or people, and one tied to your own goals. Practice it, see a model answer
Tell me about a time you solved a difficult problem.
The problem in one line, how you broke it down, what you tried that failed and the result in a number. Practice it, see a model answer
Drilling for a Potential Test format from a prep site, when your office's page names a cognitive test, a numerical test or the CCA. Read your office's page first.
In the US the CCA arrives within 90 minutes and closes 48 hours later.
The cognitive test in Switzerland, Germany and Austria allows no tools, and the Nordic logic test allows no calculator. Practice mental math the same way.
BCG says they have no right or wrong answers. In our experience, consistent honest answers beat a guess at the ideal profile.
BCG says CCA results are read alongside the rest of your application. In our experience your resume and the case still carry most of the weight.
Our plan, matched to what BCG's pages say.
First
US, Canada and Mexico: the CCA. Switzerland, Germany and Austria: the 30-minute cognitive test. London and Australia: a numerical assessment. Nordics: the logic test. Several offices add an online case.
Daily
Percent change, margins and ratios from small tables, with no calculator, against a timer.
Logic
Short sets at about 22.5 seconds a question, then review every miss for the rule you skipped.
CCA
BCG counts them in the 30 to 35 minutes and encourages them. Take it in one quiet sitting.
From BCG: CCA FAQs (PDF).
Case
On the BCG pages we read, an online case or case interviews follow the test, so keep your case practice going through test week.
From each office's own page. Your invitation is the final word on what you take.
The Online Case Experience is a chatbot-guided business case of about 30 minutes in English. Associates also take the CCA, about 30 minutes, which BCG Mexico says needs no preparation.
BCG Mexico: careersThe Online Case Experience gives 30 minutes on quantitative skills, data interpretation, calculations and business logic, then a 1-minute video of your recommendation.
BCG Argentina: careersFor the October 31 deadline, the online test ran November 5 to 12 as a group Zoom session, before first-round interviews from November 19.
BCG Czech Republic: careersEach application wave lists an entry online test shortly after application feedback and before first-round interviews. The next deadline listed is February 14, 2027.
BCG Hungary and Romania: careersEach country page says two interview rounds are complemented by online assessments. The steps list an online test with interview round one, then a personality test and interview round two.
BCG Denmark: careersSoreno's AI interviewer runs BCG-style cases out loud, asks follow-ups and scores your structure, math and recommendation. The practice items here are Soreno's own. Soreno is not affiliated with BCG.
Prep sites describe it as a BCG business reasoning test. None of the BCG careers pages we read on November 3, 2026 mention it, so treat any description of its length, scoring or pass mark as unconfirmed, and prepare for the test your office's page names.
Not under that name on the pages we read. BCG's pages describe the Consulting Career Assessment in the US, Canada and Mexico, a cognitive test in Switzerland, Germany and Austria, numerical assessments in London and Australia and New Zealand, and a logic test in the Nordics.
It depends on the office. In the US it is the Consulting Career Assessment, about 30 to 35 minutes, due 48 hours after the invitation, and select candidates then take the online case. BCG's FAQ says only some positions ask for an online assessment.
BCG Mexico's CCA FAQ, last updated December 2024, says SHL designs and administers it and that it is customized to BCG.
In the CCA, yes, BCG Mexico's FAQ says. In the cognitive test in Switzerland, Germany and Austria, questions are answered without any tools, and the Nordic logic test allows no calculator.
BCG Mexico's FAQ says no. A CCA taken for a US application in the past year carries over, and BCG Unlock says a score from the last 12 months is linked to your profile.
No. In the US the CCA comes first and a select group then takes the online case, about 35 minutes (about 40 for MBAs). The online case has its own guide.
BCG says no study is needed and the behavioral questions have no right answers. Mental math practice still helps with the logic portion, and the built-in practice questions are worth doing.
None of the BCG careers pages we read on November 3, 2026 mention pymetrics or games. The tests they describe are listed above.
