BCG Online Case (2025)
The Ultimate Guide for the BCG Online Case
(AKA Casey Chatbot Assessment)
Contents
After weeks of hard work networking and improving your resume and cover letter, you finally submitted your application and took your first step towards your dream of becoming a BCGer.
A few days later, you get what you have been waiting for…
An email inviting you to the first stage of the process – the Online Case Assessment.
Excited, you quickly open the email…
“You are invited to complete the BCG online case study. This is enabled by Casey, a friendly chatbot that tests your problem solving skills.”
Now you are confused…
“What? A chatbot?”
Several years back, BCG introduced the chatbot called Casey as a replacement for the traditional Potential Test, which had been used for many years. It was an unexpected move, given that ChatGPT and generative AI was not even a thing yet.
Remember when you had to take problem-solving tests or case with humans to get a consulting job?
It seems that’s no longer the case 😅.
Welcome to the future of consulting applications.
This is a big change from the past, and present its own set of unique challenges.
But you don’t have to worry.
In this article, I will explain everything you need to know about the test so that you can be perfectly prepared and overcome the major obstacles in the BCG Online Case.
Let’s start!
P.S.: This article is quite long (around 30 minutes to fully read it).
However, if you read until the end, I promise that you will learn more than from any other article online, and even most paid guides on the topic.
Study tip: If you are short on time, you can bookmark the URL and come back to this later for a deep dive.
Do you want to practice the BCG Chatbot in advance?
Have a look at the BCG Casey chatbot software simulation I created, now with the option to get up to 6 chatbot tests!
This is the ONLY Casey Chatbot simulation on the market with a 60-day, 100% money-back guarantee offering you the opportunity to practice for the Online Case before the actual test!
What is the BCG Online Case Assessment?
The BCG Online Case Assessment, also known as the Casey Chatbot or BCG test, is a case with 8-10 questions delivered through a chatbot, followed by a single question to record performed with a one-way video interview.
In its latest version, candidates are given between 25 to 30 minutes to complete all the questions (the actual time depends on the number of questions).
Typically, the Online Case must be completed within 3-7 days of receiving the link (it varies by the office).
⚠️ NEW – SEPTEMBER 2024 ⚠️
- A test called the BCG HireQuotient online assessment is being used in some offices (e.g., SEA)—do not worry as this is just a rebranded BCG Online Case (Chatbot)
- The main difference is that the chatbot is now hosted on the HireQuotient platform, where you will have to turn on your web cam (you will be recorded in the top-left of your screenshot)
- BCG states that the change is to protect against fraud and suspicious activities (e.g., tab switching, copy-pasting, window switching)
- Other reported differences include: (1) up to 35 minutes for the test (still 8-10 of the same question types); and (2) the Video Assessment being done in the same platform itself (instead of going to another platform / page)
- The strategies outlined in this post are still relevant for this new format
It is usually a pre-interview step, but it may also be part of the Round 1 interviews in certain offices. In such cases, both the in-person and chatbot performance will be considered together.
Regardless of when it is attempted, candidates often hear back within 2 weeks and failure normally results in a 1 or 2-year hiring ban.
If you have researched the Online Case before this article, you might have read some information telling you about how the BCG test is fully multiple-choice with 4+ options for each question, how you can skip questions, and how wrong answers will decrease the total score.
But actually, that’s not how it works. That’s outdated information about the Potential Test, which is no longer used.
The new BCG Online Case Assessment combines multiple-choice and open questions, with a video assessment at the end, and without the option of moving freely between questions.
So, in short, there are two sections in the test:
- One chatbot case
- One video interview assessment
So, that’s also what you have to prepare for. Anything else is just a distraction.
Don’t worry, if there are any changes to this, I will update this article right away. I created the first software simulation on the new Online Case with tens of 5-star reviews, and I refund everyone who doesn’t pass the test. So I have skin in the game, and need to keep my stuff updated; otherwise, I have to refund candidates!
⚠️ PLEASE TAKE NOTE ⚠️
- In Germany, a Cognitive Test is used instead of the Casey Chatbot Assessment.
- In August 2024, BCG has also released the Consulting Career Assessment (CCA) as a pre-screening step (separate and in-addition to the chatbot) in some markets.
- In this article, I will focus on the Online Case only. I will briefly cover the other assessments later, but I will only provide a deep dive on them in another article.
With this in mind, our goal today is simple: help you excel in both parts of the Online Case and secure your BCG interview invitation.
You can skip the info related to the old Potential Test, as it is no longer relevant. I know that, cause I get daily, real-time updates from candidates using my chatbot simulation, and as of today (March 2025), the Potential Test is not in use.
However, if you still want to prepare for it or simply want to check it out, my 23-question Potential Test is available for FREE within my software simulation here.
In this article, I will cover for you:
- The structure of the Online Case.
- The approaches to tackle the various question types within the assessment.
- The key tips and best ways to practice/ prepare for the assessment.
- A brief overview of the other assessments used by BCG.
- The most commonly asked questions related to the BCG chatbot assessment.
Are you ready?
Then let’s start our journey!
How is the Chatbot Case structured?
The first part of the Online Case Assessment is the interactive Chatbot Case.
Think of it as the most “interviewer”-led case interview you will ever face.
You will be given a case prompt by your “interviewer” (called Casey). Based on this prompt, you will be asked 8-10 questions, shared sequentially (that is, once you answer question 1, you will be asked question 2). Questions cannot be skipped and it is not possible to go back to the previous questions.
The goal of this section is to answer as many of the questions correctly as possible in the allocated 25-30 minutes.
These 8-10 questions can take 2 forms: multiple choice & open question.
Form 1: Multiple Choice
The screenshot above is an example of a multiple choice question (adapted from my guide).
They usually form the majority (5+) of questions and allow 4 to 8 different answers.
The questions can be on any of the following types:
- Structuring
- Business sense
- Math
- Graphs
Later on, I will cover each question type along with an approach to tackle each one.
Form 2: Open Question
The screenshot above is an example of an open question (adapted from my guide).
These are usually the minority (3-) of questions and require candidates to write 2 to 4 lines as a response or the numerical results of a math question.
The questions can be on any of the following types:
- Structuring
- Business sense
- Math
- Graphs
- Synthesis
Don’t worry, because I will cover an approach to tackle each of these question types later on.

How is the Video Assessment structured?
The second part of the Online Case Assessment is a one-way video interview.
Candidates are given a question, usually the conclusion of the case. They then spend 1 minute preparing their answer and another 1 minute recording it with both audio and video.
The interface looks something like the following (source: my guide):
While 2 attempts were allowed previously, the most recent version (March 2025) allows only 1 attempt.
The Video Assessment tests the synthesis skills of a candidate. In a later section, I will share a strategy to tackle the recording.
Do you want to perfect your Video Assessment performance?
A good answer in the video assessment is not just based on what you say, but also on how you say it: tone of voice, speech clarity, energy, you name it!
In my BCG Online Case software simulation, you will get a complete AI report evaluating your one-way video interview performance and providing an assessment on your body language, clarity, energy and even emotion and dress code!
This is the ONLY simulation on the market with a 60-day, 100% money-back guarantee, offering you the opportunity to refine your video interview performance before the actual test!
How can I crack the 5 question types?
So, as we saw, there are 5 key question types. How can you answer each of them?
To understand that, let’s review which are the key questions of the Casey Assessment:
These questions replicate what you would face in an actual in-person interview (minus the actual human interviewer part 😅). They want to understand how you perform on the same areas covered in a typical case interview. You will be evaluated on:
- How you organize different piece of information and understand the cause and effect between them
- How you make decisions in complex situations
- How you structure formulas and perform computations based on provided data
- How you identify insights from data and make conclusions based on them
- How you summarize your findings
For this reason, most of what you do in a case applies here as well. However, given you cannot interact with the interviewer, there are still some important differences.
Let’s now review each of these questions (click on the tabs below to read more):
Structuring Questions
Structuring questions are one of the most common question types in Casey.
They typically take the form of a multiple choice question where you select the most relevant factors/ elements from a list. Think of this as selecting the option you would want to explore in what would have been your issue tree.
This multiple choice selection is usually followed by an open question asking you to explain your reasoning for selecting those factors in a few lines.
In some cases, Casey may combine both and just ask you for the elements/ factors and rationale directly via an open question.
An example of a Structuring question (adapted from my guide). Try it out yourself using the approach below before checking out the answer in the next image
This question type is most likely to appear:
- At the very beginning of the case, where you typically have to choose between ~8 different options
- During the case, where you mostly choose between ~4 different options
To answer such questions, I would suggest a 3-step approach:
-
Understand the goal:
- The objective is often very specific but might not be very obvious in the prompt.
- Since you will not be able to clarify, make sure you spend time re-reading the prompt.
- You need to understand the objective thoroughly as you will be structuring around it.
-
Structure an approach:
- Now that you have your objective, use it as a reference to break down the problem and isolate components needed to answer the question.
-
Identify the information needed:
- Once your structure is ready, look at the options available to you and select those that match the issues/ elements you identified.
- In the case of open questions, simply list out the issues/ elements and your rationale for considering them.
It is critical to start from a structure as the options provided are often quite similar, making an ‘elimination’ method difficult.
Did you get it right? 🤔 You can find a comparable question with complete answer explanation in the PDF Guide included for FREE with the BCG Simulation.
Business Sense Questions
Business sense questions are those that seek to find the best solution for a specific business problem.
They almost always appear in the middle of the case and typically involve selection from ~4 possible answers. Unlike structuring questions, you normally cannot identify the ideal answer just from the prompt/question asked. Instead, you will have to review the possible options and choose the best one available.
Like structuring questions, they may be followed by open questions asking you to justify your choice or both questions may be merged into one single open question itself.
An example of a Business Sense question (adapted from my guide). Which of the options would you choose?
Since it is usually impossible to structure an approach for such problems without reading the answers first, an elimination-based approach is recommended here:
-
Understand the objective:
- Like for structuring questions, full understanding of the objective is key.
- Take your time to digest the question/ prompt before answering accordingly.
-
Read the options & eliminate irrelevant options:
- Once you understand the objective, review the options given to you and eliminate those that are unrelated to the objective.
-
Select the residuals:
- Before selecting whatever options remain, double check them to make sure they fit the specific question asked.
In the event that you face an open question variant of the Business Sense question, simply think about the objective and share your thoughts accordingly since you are not constraint by the options available to you.
The elimination-based approach was used to arrive at the answer above
Math Questions
Math questions typically appear in the middle or at the end of the case.
They can be either:
- Multiple choice, in which case you will typically have ~5 options; OR
- An open question, where you need to state your final result
An example of a Math question with multiple choices (adapted from my guide)
Math questions are often considered the most difficult part of the Casey Assessment, not because the questions are particularly difficult (it’s not more difficult than your typical case math), but simply because there is a lot of tedious math to go through within a limited time.
Accordingly, I recommend the following approach:
-
Define the formula:
- Spend extra time to understand the exact question asked and the data provided, then identify the formula (or set of formulas) to answer accordingly.
- Remember, the math in Casey is often very long, and you will waste a lot of time if you realize you approached it wrong after starting and need to change your approach.
-
Perform the math:
- Calculators are allowed as part of the test; thus, make sure you make full use of them to maximize speed.
- Ensure you enter your numbers properly though (especially critical for those of you who do not use calculators regularly).
-
Double check if the numbers make sense:
- If time allows, redo the math to ensure there are no mistakes.
- If this is not possible, at least check if the order of magnitude makes sense (remember, no extra or fewer zeros!).
Did you arrive at the same answer?
Graph Interpretation Questions
Graph interpretation questions are… well… I think the name explains itself!
You will be given one or more graphs and asked to derive insights or make inferences from them.
An example would be 2-3 graphs showing the financial performance of the client across different dimensions, and being asked to determine what is driving their declining profits.
This question type normally appears in the middle or at the end of a case, and usually takes the form of an open question. However, you could also receive a multiple choice question followed by an open question for the rationale. You will usually also have to perform some math to reach an answer.
An example of a Graph Interpretation question
Accordingly, I suggest the following to tackle such questions:
-
Understand the objective:
- Make sure you understand what exactly is asked of you so that you can tailor your response accordingly.
-
Analyze the graph:
- Read the graph (or graphs), identifying the key trends present.
- Note that if multiple graphs are shared with you, some trends might only be obvious when comparing across the graphs.
-
Define a formula to answer the question:
- Define a structure or equation to connect the graph information to the question asked and derive the answer accordingly.
Check out my guide for examples of multi-graph questions and answers 🤓
Synthesis Questions
Synthesis questions are where you sum up the case.
It can:
- Appear as the last question of the chatbot, where you must share your recommendations in 3-4 lines; OR
- More typically, appear as the Video Assessment question, where you need to record yourself presenting the sum-up of the case.
An example of a Synthesis question (adapted from my guide). This variation is rarer as Synthesis questions usually appear in the Video Assessment
Regardless of the section in which it appears, the structure for the conclusion is the same as the one you have to provide an in-person case interview:
-
Repeat the objective:
- Briefly repeat the information provided in the initial prompt.
- Keep it short and sweet – ideally within 1 line.
-
Provide an answer-first conclusion:
- Present your findings, mentioning first the direct answer to the case question, followed by your supporting points.
- Make sure they are structured and clear by labeling them with “First,… Second, … Third, …”.
-
Present the risks and next steps:
- Explain what you would recommend to do as next steps, and any possible risks associated with the final decision.

What are the must-know tips for the BCG Online Case?
I have helped 1,000+ candidates crack the Online Case Assessment since it was launched by BCG.
Here are some of the top tips to make sure you join them in acing the test and getting your interviews (click on the tabs below to read more):
Tip #1: Check if the Chatbot Interview is part of your selection process
Several years after initial launch, the Casey Chatbot is now THE assessment method of choice for BCG offices across the globe. Nonetheless, as of March 2025, some offices (e.g., the German ones) have begun using an alternative assessment known as the Cognitive Test, although these are still the minority.
Therefore, make sure you are clear on the test that you have to take to avoid wasting time on the wrong preparation. If you are in doubt, you can always clarify with HR before preparing.
Tip #2: Start your prep early
Invitations to the BCG Online Case often comes quickly after initial application, and you will have a week or less to complete the test.
The Online Case tests the same skills as regular case interviews, and most candidates take weeks to prepare for those. So, be sure to start your preparation early!
If you only found out about the test days before the deadline – it’s not too late! My BCG Combo was spefifically designed to get you up to speed on the Casey test within a few hours.
Tip #3: Build up a casing routine
Since the Online Case Assessment mimics the actual case interview, practicing cases would be the most efficient way to prepare for it (and since you need to practice cases anyways, the work you put in will benefit you even after the test).
There are 3 primarily ways to prepare for case interviews:
- Practicing on your own using casebooks from top business schools (e.g., reading the prompt > structuring your response > checking the answer)
- Practicing with your friends (ideally those who are consultants)
- Practicing with peers on P2P platforms such as PrepLounge
Practicing with friends/ acquittances who are current/ ex-consultants is obviously the best choice – they are experienced, give relevant feedback, and you do not need to return the case (saving you time!); unfortunately, this option is often not available to everyone.
Therefore, for most people, the real alternatives are 1 and 3. Practicing on your own restricts your ability to practice communication skills (although this is less important for Casey), while P2P platforms require more time commitment to return the case and feedback might not be the best. A combination of both could be a good mix.
Tip #4: Leverage the Casey tutorial
It doesn’t matter how many cases you do beforehand if you are unfamiliar with chatbot cases.
A different interface, the inability to clarify, the ticking timer at the top – all factors that will make casing with a chatbot disorientating for candidates.
BCG will share a mock Casey case with you as a tutorial. Make sure you attempt that at least once to get familiar with how the Assessment works. If you want to do additional practice, my software simulation can help with that as it provides 4 different Casey-style chatbots inspired by the real thing, with the option to add more if you wish.
Tip #5: Work on case math under strict time limits
Case math is often considered as the most difficult part of the Casey Chatbot cases. However, the difficulty is not solely in the questions themselves (they are no more difficult than the questions you get in real cases), but mostly in the time constraint.
Casey math has usually multiple steps and it is tedious, and with the timer running down at the top of your screen, it is no wonder that candidates struggle with the math questions.
Practicing on live Casey-style chatbots would be the best, but you can also improve your comfort level with complicated case math under time constraints by working on:
- BCG Potential Tests (I have a specially-crafted set of 23-questions to improve your case math included as part of my Combo)
- McKinsey PSTs (below are some links to free ones)
For the most effective prep, make sure you use strict time limits when attempting the practice tests. This means spending ~2 minutes per question. Where possible, also practice with these tests on a computer to better replicate the Online Case experience.
Tip #6: Optimize your test environment and get into the zone
Every little advantage counts when an interview invite is on the line. Therefore, here are some test-day tips:
- Set up a silent room and let your family/ friends know that you are taking an important test so that there are no interruptions
- Check your internet connection, webcam, and microphone
- Prepare your pens, papers, and calculator
- Dress formally for the one-way video interview (do they really take into account how you dress? We don’t know for sure, but why take a risk?)
- Listen to high-frequency music (e.g., www.brain.fm) to help with concentration (be sure to test this out before test day and only use this if it helps)
Tip #7: Don't panic if you start slow
While the recommended time to spend on each question is ~3 minutes, it is perfectly normal to spend more time on certain questions, specifically the first one (where you need time to properly digest the prompt and overall objective) and the subsequent math questions.
In fact, it is worth investing more time on the first question in order to get the correct results, as you can easily make up time in other, more straightforward questions (e.g., those related to business sense). However, avoid spending more than 4-5 minutes on a question, as most likely you won’t be able to finish the test otherwise. If you find yourself spending more than that, I would recommend providing a best-guess answer and move on.
Tip #8: Make full use of the break before the video interview
The video assessment only allocates 1 minute for you to prepare your answer, but there is a workaround to this:
After the chatbot, the video assessment does not start until you select “Next”; therefore, you can spend more time and prepare your answer in advance before proceeding, especially since the question will almost always be related to the case sum-up/ recommendation. In fact, you can even record yourself presenting the recommendation a few times to make sure you got everything right and within the 1-minute window.
If you want to make your recommendation is really full-proof, check out my BCG Combo, which includes AI-assessed one-way video interviews that will evaluate your performance in terms of voice, speech clarity, energy, and more.

What about the other assessments used by BCG?
Well, as promised, here is an overview of the other assessments used by BCG. Note that this is just an overview and a deep dive will have to wait for another article (watch this space 😉).
I would not worry about the other tests if HR does not mention them as the Casey Chatbot is by far the most common assessment method used as of March 2025.
Nonetheless, you can find a summary below (click on the tabs to read more):
BCG Potential Test
Note: The BCG Potential Test is already phased out and no longer used (I had no reports of its usage from the candidates I helped as of today [March 2025]).
However, since you are interested:
The BCG Potential Test was a computer-based test used to evaluate candidates on their analytical, logical, and problem-solving skills.
It consisted of 23 multiple-choice questions that you must complete within 45 minutes. All 23 questions are related to a single overall case and it is possible to skip back and forth between the questions. Calculators were generally not allowed except for a few countries (where HR would clarify the fact).
What made the test unique was its scoring system:
- candidates received +3 points for the right answer
- 0 for missing/ no answers
- -1 for wrong answers
… and this unique scoring system informed the test strategy where skipping a question was better than making a random guess.
Fun fact: the Potential Test was also called the BCG Online Case back in the day, which is one of the reasons for the confusion between this and the Casey Chatbot.
Like the Casey test, the Potential Test could be a pre-interview screening test or part of Round 1 itself, with 70% of the maximum total score being the rumored passing cut-off.
Despite not being used anymore, the Potential Test can still be a great way to practice case math for the new Online Case (that is why I included my custom-crafted Potential Test as part of the BCG Combo).
BCG Cognitive Test
The BCG Cognitive Test is a new assessment method introduced by BCG in early-2024. As of March 2025, it is only used in a small number of offices, including Germany, where it substitutes the Casey Chatbot.
The BCG Cognitive Test is a proctored (that is, you will be monitored live via Zoom) numerical and logical assessment designed to stress test a candidate’s reasoning skills. And I meant it when I said “stress test” because candidates are given 80 questions to complete within 30 minutes – that is less than 30 seconds a question!
In all likelihood, BCG does not expect candidates to complete all 80 questions accurately; instead, the Cognitive Test likely evaluates a candidate’s ability to solve quantitative/ logical problems under significant time pressure.
A deep dive on the Cognitive Test will come later, but for now, here are some tips:
- Tip 1: Prepare in advance with similar drills (you can find below a few links to free resources)
- Tip 2: Target ~20 seconds per question (you don’t need to answer all 80, but try to get as close to it as you can)
- Tip 3: Set a deadline to move on if you are stuck on a question (I would recommend max 1 minute)

BCG Consulting Career Assessment
The BCG Consulting Career Assessment (CCA) is a new assessment introduced in August 2024.
The test is sent out soon after you submit your application, and your performance in this test will determine whether you proceed with the BCG Online Case. In other words, the CCA is in addition to the Casey Chatbot, providing an extra data point for recruiters to decide whether to proceed you along the interview process. Upon receiving the link, you will have 24 hours to complete the test.
The CCA is entirely computer-based, with no requirement of turning on your webcam, and with calculators being allowed. BCG recommends around 30 minutes for the test, but only 1 section is timed.
The sections of the CCA include:
- Instruction Review (~20 minutes): You will be introduced to the test format and provided with instructions on how to proceed with the test.
- Behavioral Questions (Untimed): You will be asked to pick 1 out of 3 phrases that describes you best in various situations/ contexts. These situations/ contexts are based around several themes including interpersonal communication, leadership, empathy, etc. Like all personality/ behavioral tests, this section does not have clear right or wrong answers; instead, your responses will likely be compared against traits valued by BCG in their consultants.
- Math & Logic Questions (12 minutes): You will be asked 8 questions focused more on logic and pattern recognition than quantitative problem solving (imagine questions on logical sequences, calendar scheduling based on participant availability information, etc.).
The only difficult part of the CCA is the Math & Logic section due to it being timed and the questions being intentionally ambiguous (some candidates report that many questions appear to have more than 1 answer). On the other hand, the CCA also comes with 4 practice questions for the Math & Logic section, which are reportedly very similar to the ones faced later on; so you do not need to worry about going in blind!
BCG Pymetrics
Pymetrics is a leading talent assessment platform that uses a series of neuroscience games and AI to help employers better understand their job candidates. It is widely used by many different top employers, so if you have been active in the job market, you likely encountered the games before.
As part of the BCG Pymetrics assessment, candidates will be asked to play 12 games that take approximately 1-3 minutes each, with the whole process taking 20-30 minutes in total. The games are non-continuous, which means you can take a break between the games.
The 12 games are:
- Balloons: You will pump balloons to accumulate money; the more you pump a balloon, the more money you get, but you get nothing if the balloon pops before you collect their prize.
- Money Exchange #1: You will be given a sum of money and you must then engage in an monetary exchange with an AI partner.
- Money Exchange #2: Same as #1 but with some variation in the circumstances/ context.
- Digits: You will be shown an growing sequence of numbers and evaluated on how much you can remember.
- Easy or Hard: You will choose between easy and hard tasks, each with different rewards, with the end goal of maximizing earnings while minimizing effort.
- Stop: You will see red and green circles flashing in your screen and you will have to hit the spacebar upon seeing the red circle.
- Cards: You will draw cards from 4 different decks, each with different odds of winning and losing, with the end goal of maximizing the amount of money.
- Arrows: You will be shown a series of arrow sequences and will have to react accordingly based on the color and direction of the arrows.
- Lengths: You will be shown emoji faces and have to determine whether the mouth on those faces are long or short.
- Towers: You will be given 3 ‘towers’ with a set of colored rings arranged on them; within the fewest number of moves, you will have to move the rings between the towers until their towers matches a target formation.
- Key press: You will have to hit your spacebars as quickly as possible when you see the word “GO” on your screens.
- Faces: You will be shown photos of people with various facial expressions (sometimes accompanied by a short story about the context behind those expressions); you will have to select 1 out of 10 adjectives that best describes the person’s expression.
Pymetrics only allows candidates to play the games once every 330 days. If a candidate has completed all the games within the 330-day window, they will not be able to play the games again and, upon logging in to the portal, the existing results will be used by BCG. If the 330-day window has passed, a candidate can choose to re-play the games and submit the new results.

Wait! I have a ton of other questions on the Online Case...
Need more help? Don’t worry, I have compiled for you some of the most common questions about the BCG test below. Let’s get started!
Click on the tabs below to read more:
How are candidates scored in the Online Case?
Can I take the Assessment at home?
Yes, of course. One of the main objectives of these screening tests is to provide more flexibility and reach more candidates with minimal effort. As such, you can take the Casey test anywhere, including from the comfort of your own home.
How do I know if my BCG office has the chatbot?
To the best of my knowledge, the vast majority of offices (excluding some like the German ones) use the Casey Chatbot Assessment.
In any case, you will receive an email from BCG confirming the test/ assessment that you will have to take.
Will I receive a score for my performance after the BCG Casey Assessment?
Usually, you will not receive a score but rather just a confirmation of whether you passed the test or not.
I have to take the BCG Online Case, but I found information online about the Casey Chatbot and the Potential Test; are these all the same?
I admit, this is a bit confusing, but essentially:
- The current version of the BCG Online Case Assessment involves casing with a chatbot called Casey, hence the alternative name: Casey Chatbot test
- The Potential Test was the previous assessment used by BCG and is no longer in use; unfortunately, it was also called the BCG Online Case, causing a lot of confusion amongst candidates
Why is the test also called “Casey”?
Casey is the name of the chatbot (developed by a former BCG Principal) that BCG uses to deliver the Online Case Assessment. Hence, both “Casey” and the “Online Case” are used interchangeably to refer to the chatbot test.
I received the BCG HireQuotient Online Assessment, is it the same test?
Yes, the BCG HireQuotient online assessment is just a rebranded BCG Online Case (Chatbot) being used in some offices (e.g., SEA).
The main difference is that the chatbot is now hosted on the HireQuotient platform, where you will have to turn on your web cam (you will be recorded in the top-left of your screenshot). BCG states that the change is to protect against fraud and suspicious activities (e.g., tab switching, copy-pasting, window switching).
Other reported differences include:
- Up to 35 minutes for the test (still 8-10 of the same question types); and
- The Video Assessment being done in the same platform itself (instead of going to another platform / page).
Accordingly, the strategies outlined in this post are still relevant for this new format.
I am applying to a sub-group under BCG. Will I have to take the test?
It depends, some do while others (e.g., INVERTO in SEA) do not.
In any case, your HR will inform you of any test that you would have to take.
Is there any simulation of the Online Case Assessment? What is the best BCG test practice tool that I can use?
Yes. I have created a simulation of the Online Case Assessment. You will have lifetime access to 4 live Casey-style chatbots and AI-assessed video interviews, and you can practice with them an unlimited number of times.
You can buy it using this link, where you will also have the option to add on an extra 4 live chatbot cases and one-way video interviews. Furthermore, it comes with a 100% money-back guarantee if you do not pass the test within 60 days post-purchase.
Once you have practiced with the simulations, I guarantee (and I mean it!) that you will not have any surprises during the Assessment and you will have all the tools needed to ace the BCG test.
Is the webcam working during the BCG Online Case? Can they watch candidates attempt the test?
Yes and no. Your webcam will only be needed for the Video Assessment at the end. For the Casey Chatbot itself, your webcam will not be needed and it will not record what you do at any time. The audio will not be active either.
My friend took the Online Case Assessment recently and shared his answer with me. Am I ready for the test?
There is no guarantee that this will work, because BCG has a set of cases in use at any one time.
The case your friend got will most likely not be the one you will get.
Does everyone get the BCG Casey test? I am an experienced hire, do I have to take the test?
Typically, the Casey Chatbot Assessment is used for entry-level roles (i.e., immediately/ shortly after university/ MBA), so if you are applying for those roles, most likely you will need to attempt the chatbot.
What if I get the Potential Test?
As of March 2025 (when you read this as I update this article in real-time whenever there is a relevant update), the Potential Test is no longer in use.
If you still want to prepare for it, you can find a set which I included for free with my Chatbot Simulation.
I received the test invitation. Does this mean I have passed the CV screening?
Most likely.
In almost all cases, BCG performs the resume screening before the Casey test. Therefore, receiving an invitation for the chatbot from BCG typically means that you cleared the initial screening.
How important is the Online Case?
Very important.
In most markets, the Online Case determines whether you make it to the interview stage or not; while in others, it will be evaluated alongside your Round 1 interviews. Therefore, underperforming in the Online Case will affect your chances of a BCG offer.
Do interviews take place only after the BCG assessment?
Not necessarily.
In some markets, the Online Case is attempted together with the Round 1 interviews. In such cases, candidates are evaluated on both their in-person and chatbot casing performance when deciding whether to move them to Round 2.
How much time do I have to complete the test?
Usually candidates must complete the test within 3 to 7 days. They will inform you about the exact amount of time when you receive the invitation email from BCG.
Why did BCG change the assessment from the Potential Test to the Casey Chatbot?
There are a few reasons why BCG switched to the Chatbot in their recruitment process. In my opinion, the most relevant one would be that it is able to test more dimensions of what makes a good consultant, and therefore provide a more comprehensive evaluation of whether a candidate would succeed on the job. This indirectly also means that, if used before the interviews, candidates making it to the interviews will be of a higher standard.
The Potential Test does not provide such a comprehensive view as it does not test elements like communication skills.
What is the BCG Online Case assessment's passing rate?
No one knows the exact metric but usually these tests can screen out up to 70% of the candidates. This is assuming that the test is done before the interviews. If you are attempting the Casey Chatbot as part of your Round 1, then your in-person case performance will also be considered.
What is the best way to prepare for the test?
I am biased on this because I created a comprehensive product exactly on the Online Case 😉 You can find it here.
I can provide you with three good reasons why I think my BCG Combo is the best resource to prepare:
- The Combo is the fastest way to be ready for the test. You will learn everything you need to know about the Online Case assessment in just a few hours.
- The Combo has the best money-back guarantee in the market. If you do not pass, you get 100% money back thanks to my 60-day guarantee.
- The Combo is the best package overall, including a 144-page pdf guide with 2 extra PDF chatbots, strategies for all 5 question types, as well as a custom-crafted Potential Test to practice even further.
Plus, if you want, you can also add an additional 4 live Casey-style chatbots and Video Assessments at checkout to get even more practice.

Ah yes, and you will also get a 100% money-back guarantee if you do not pass within 60 days. Just send me the rejection email of the test and I will refund the course.
The only reason I can offer this is that I know the course works and you will pass the BCG Online Case Assessment and move to the case interview stage (if you come across comparable claims: ask them why they do not offer a full guarantee ;)).

Thanks for the article! How much time would you recommend to spend on the guide before the test itself? Do you recommend starting before the invite?
Hi Sean, thanks for reaching out! Depending on the number of chatbots you would like to use for practice, 5 to 10 hours should be enough (you can assume ~1 hour per chatbot). Based on that, you might opt to start earlier in case you don’t have much time after the invitation. Good luck!
