Gamified assessment
BCG Casey and the Online Case
The Boston Consulting Group screens applicants using a sophisticated, chatbot-led digital assessment known as Casey. This online case simulates the core components of a traditional consulting interview, requiring you to structure business problems, evaluate dense data exhibits, execute precise quantitative calculations, and deliver a structured recommendation under strict time limits. This comprehensive guide details what the assessment measures, how the system operates, and how to prepare effectively to pass the screening stage.
In short
The BCG Casey assessment is an interactive, chatbot-led online case interview that filters candidates before live interviews. Operating within a simulated text-messaging interface, you are presented with a real-world client problem and must complete 8 to 10 sequential questions spanning problem structuring, graph interpretation, data analysis, and multi-step business math. The test concludes with a short, video-recorded recommendation. To pass, you must demonstrate structural clarity via mutually exclusive and collectively exhaustive logic, maintain high arithmetic accuracy under tight time pressure, and synthesise data into a concise, driver-led strategic conclusion.
The basics
What it is
The BCG Casey online case represents a structural shift in how management consulting firms execute early-stage candidate filtering. Instead of deploying human interviewers to conduct initial screening rounds, BCG uses an interactive chatbot named Casey to deliver a standardised, automated simulation of a case interview. The system functions through a forward-only messaging interface where the bot introduces a client company, outlines an operational or strategic problem, and systematically tests your analytical capacity through an algorithmic sequence of prompts.
Depending on the specific office and application cycle, this chatbot case is frequently paired with a game-based or psychometric component designed to profile your cognitive and behavioural traits. Historically anchored around neuroscience mini-games, this dual-layer assessment architecture creates a comprehensive performance profile. It allows BCG to evaluate hundreds of thousands of applicants globally across both the UK graduate scheme and US undergraduate or summer associate pipelines, identifying individuals who possess the fundamental problem-solving architecture required for management consulting before allocating expensive partner or principal time to live interviews.
For candidates navigating the recruitment pipeline across multiple geographic markets, the Casey platform provides a uniform evaluation standard. A candidate applying for a London-based associate role or a New York-based summer consultant position will face the same core assessment mechanics. The digital interface eliminates geographic and interviewer bias by forcing every applicant to respond to identical data sets, rigid question time limits, and unyielding logical gates where answers must be locked in before the system allows you to progress through the case ecosystem.

What it measures
The dimensions under test
Issue structuring and MECE frameworks
The assessment evaluates your ability to break a complex, ambiguous business problem into distinct, manageable analytical categories. You must demonstrate mutually exclusive and collectively exhaustive logic when choosing which data streams to investigate or isolating primary cost and revenue drivers.
Quantitative analysis under time pressure
You are evaluated on your capacity to execute multi-step business arithmetic rapidly and accurately. This includes calculating gross profit margins, break-even volumes, compounded annual growth rates, and weighted averages based on data fragments provided within the chat interface.
Exhibit interpretation and data synthesis
The test measures how effectively you isolate critical insights from dense visual assets. You must look past filler data inside tables, multi-axis charts, and segmented bar graphs to identify absolute trends, relative percentages, and structural shifts that directly impact the core business objective.
Business judgment and strategic prioritization
This measures your commercial intuition when choosing between conflicting strategic options. The chatbot tests whether you can evaluate trade-offs, weigh market size against competitive intensity, and prioritize actions based on realistic operational capabilities rather than abstract theories.
Written communication and clarity
Through short-answer text boxes, you are assessed on your ability to articulate business hypotheses and rationales without fluff. The platform parses whether you can state an assertion clearly, list supporting data points systematically, and convey complex logic in a brief, professional manner.
Cognitive and behavioural traits
When paired with the game-based component, the assessment evaluates underlying psychological attributes. It tracks your risk tolerance, attention direction, learning speed from changing patterns, processing capacity, and consistency under shifting performance conditions to create an objective, non-resume behavioral profile.

What to expect
See it in action
A worked example
The following walkthrough demonstrates how an applicant executes an original mini-case turn end-to-end within the structured chatbot interface.
- 01
Problem scoping and dataset selection
The chatbot introduces a premium coffee brand experiencing a drop in operating profits from 15 percent to 8 percent over two years. The system prompts you to select the three most vital data vectors from a list of eight options; a strong response bypasses macroeconomic weather data and explicitly selects historical unit sales volume, per-kilogram bean procurement costs, and regional retail pricing structures.
- 02
Exhibit interpretation and axis validation
Casey serves a dual-axis chart showing product revenue on the left vertical axis in millions of dollars and distribution fees on the right vertical axis in local currency per shipment. You inspect the units carefully to confirm that while domestic volume grew by 10 percent, outbound logistics costs spiked by 40 percent per container due to port congestion, identifying a distinct margin leakage point.
- 03
Execution of multi-step business math
The chatbot asks for the exact reduction in dollar-denominated profit if fixed operating overhead sits at 2000000 USD (1550000 GBP) and variable logistics costs increase from 5 USD to 7 USD across 300000 shipments. You run the arithmetic on your calculator: 2 USD increase multiplied by 300000 units equals an absolute profit degradation of 600000 USD (465000 GBP), entering the clean integer directly into the numeric field.
- 04
Synthesis and structured video recommendation
The screen transitions to the video module, giving you 60 seconds to outline your notes before the camera records your 60-second final presentation. You deliver a crisp delivery: "I recommend renegotiating regional distribution contracts immediately because rising logistics costs accounted for a 600000 USD margin drop, which can be mitigated by shifting 40 percent of volume to local secondary hubs while pausing premium product expansion."
The takeaway
Maintaining strict analytical discipline throughout this sequence ensures you feed the chatbot clean, logically cohesive data points that score highly across every underlying metric.
The scoring
How it is marked
The Boston Consulting Group treats its exact grading thresholds as proprietary information and does not reveal a specific numerical pass mark to applicants. Performance profiles are generated across separate assessment tracks: the Casey chatbot case evaluates core management consulting competencies including structuring, mathematical precision, and verbal synthesis, while the accompanying games generate a distinct behavioural matrix that carries no single negative penalty. Results are normally processed and delivered to candidates within one to two weeks following submission, though specific timelines vary significantly based on regional hiring cycles, local office requirements, and whether you are applying through a university superday or a lateral market pipeline.
Strong performance band
Candidates in this tier establish clear, logically exhaustive structures during dataset selection, commit zero arithmetic errors on the multi-step quantitative prompts, and deliver a video recommendation led by an explicit strategic driver supported by exact numeric data.
Solid performance band
This tier represents individuals who correctly identify the primary levers of the business problem, solve the calculations with minor timing delays, and construct a logical final recommendation that clearly covers the client objective despite minor structural omissions.
Borderline performance band
Applicants in this band display foundational problem-solving capacities but suffer noticeable slips, such as making a major calculation mistake due to inverted units, failing to finish the last case question under the clock, or delivering a vague video summary that recites facts without a clear decision.
Below the bar band
This tier is characterized by an absence of structured case discipline, resulting in erratic framework choices, repeated mathematical inaccuracies on straightforward business margins, or an inability to articulate a coherent strategic argument during the timed video recording.
The variants
Versions you might be sent
Casey the chatbot case interviewer
The standard global interface where a single business case is broken into 8 to 10 automated steps. Candidates interact with a virtual bot assistant in real time, locking in qualitative hypotheses and numeric calculations without any live human intervention.
Legacy one-way online case experience
An older, non-interactive assessment architecture still deployed by select boutique tracks or specialized international offices. This format displays a static collection of 3 to 4 documents and charts simultaneously, requiring candidates to answer 20 to 25 traditional multiple-choice questions within a rigid 45-minute limit.
Cognitive and behavioural game batteries
A psychometric layer that often pairs with the chatbot case to evaluate executive functioning. Candidates complete a rapid series of neuroscience-based tasks assessing emotional recognition from facial features, digit-span memory limits, and risk adjustments during balloon inflation simulations.
Office-specific localized builds
Custom interview configurations engineered for unique regional offices or specific recruitment tracks like BCG Gamma, digital strategy, or lateral senior hires. These variations may adjust the language settings, alternate the business contexts, or layer GMAT-style data sufficiency prompts directly into the primary testing interface.

The prep
How to prepare
Practise structuring cases using MECE logic
You must train yourself to break open ambiguous business prompts into distinct streams. Spend time mapping out custom issue trees for market entries, pricing changes, and operational cost reductions, ensuring your categories never overlap and collectively cover the entire scope of the problem.
Master core consulting math operations without spreadsheets
Drill multi-step business calculations daily under timed conditions. Focus on calculating gross and net margins, break-even thresholds, investment payback periods, percentage growth rates, and weighted averages using only scratch paper and a basic standalone desktop calculator.
Deconstruct data exhibits systematically before answering
When a chart or table appears, force yourself to spend the first fifteen seconds identifying the exact title, the vertical and horizontal axes, the explicit units of measurement, and the accompanying footnotes before attempting to select an answer or execute calculations.
Maintain emotional consistency across the games
If your assessment package includes a psychometric game battery, treat it as a low-stakes exercise by maintaining a steady, calm approach. Do not attempt to game the system or second-guess what profile the firm desires; focus on staying focused, consistent, and fast across every mini-task.
How not to fail
Common failure modes
The specific ways candidates lose marks on this test. None of these need talent to avoid, only awareness.
- 01Diving into mathematical calculations without prior structuring. Attempting to compute numbers before verifying the structural relationship between variables leads to compounding logic errors.
- 02Arithmetic slips caused by rushing the calculator. Miskeying digits or misplacing decimals under the pressure of the on-screen countdown timer results in incorrect numeric entries.
- 03Misreading or ignoring axis labels and footnotes. Failing to notice that an exhibit axis is denominated in thousands or expressed in an alternate currency causing massive scale errors.
- 04Delivering a vague recommendation without an explicit driver. Reciting a general list of case facts during the final video response instead of leading with a definitive action-oriented decision.
- 05Attempting to manipulate or outsmart the behavioural games. Changing your natural response patterns midway through the psychometric tasks creates an inconsistent, erratic profile that flags poorly.
- 06Mismanaging the on-screen countdown timer. Spending too much time on a single difficult intermediate question, leaving insufficient minutes to complete the final data prompts.
