What is the BCG Online Case or Chatbot Interview?

 

The BCG online case, also known as the BCG Casey or Chatbot Interview, is a new iteration of the traditional case interview format developed by BCG. Candidates are given a series of questions in an interactive chat format, simulating a real case interview.

 

Key features of the BCG online case or chatbot interview include:

 

  • Chatbot interaction: Candidates engage in a conversation with a chatbot named Casey, which presents questions and prompts responses in real-time

 

  • Time limit: The test typically lasts 45 minutes and includes 20+ questions. Candidates face significant time pressure as there is no option to pause the test once it begins

 

  • Various question formats: Questions can be in various formats, including multiple-select multiple choice, single-select multiple choice, long-text freeform, and short-text freeform

 

  • Final self-recorded presentation: After completing the chatbot interview, candidates are prompted to record themselves presenting their final recommendation for the case within a strict time limit

 

Overall, the BCG online case aims to simulate a realistic case interview scenario while leveraging technology to provide a convenient and accessible assessment method to evaluate prospective BCG consultants.

 

Format of the BCG Online Case / Chatbot Interview

 

The BCG online case or chatbot interview lasts 45 minutes and includes 20+ questions. There are five question formats: multiple-select multiple choice, single-select multiple choice, long-text freeform, short-text freeform, and self-recorded video.

 

On the actual online case, you will find that your screen is divided into two sides. On the left, you will find the questions and the multiple-choice answers. On the right, you’ll find the information and data needed to answer the question.

 

You are free to move forward and backwards through the online case as needed and may change your responses at any point before your time runs out.

 

1. Multiple-select multiple choice

 

In this format, candidates are presented with a question and a list of options from which they must select multiple correct answers. The number of correct answers may vary and the question may not indicate how many options should be selected.

 

2. Single-select multiple choice

 

Similar to the multiple-select format, candidates are presented with a question and a list of options, but they can only select one correct answer. Candidates must choose the one answer that best addresses the question.

 

3. Long-text freeform

 

In this format, candidates are required to provide detailed responses in a text format, typically using a message box interface. Candidates may be asked to explain their reasoning, outline a strategy, or provide qualitative insights related to the case.

 

There may be an imposed character limit, requiring candidates to provide succinct yet comprehensive answers.

 

4. Short-text freeform

 

Unlike the long-text format, the short-text freeform restricts candidates to only entering numerical responses or short text answers. Questions in this format often involve mathematical calculations or require concise textual responses.

 

5. Self-recorded video

 

For the final part of the BCG online case or chatbot interview, candidates are prompted to record themselves presenting their final recommendation or solution for the case. Candidates typically have a limited time that they can record themselves giving their presentation.

 

During the presentation, candidates are expected to articulate their thoughts clearly and deliver their recommendation confidently.

What Questions Are Asked in the BCG Online Case / Chatbot Interview?

 

There are several types of questions that are typically asked in the BCG online case or chatbot interview: structuring questions, quantitative questions, critical thinking questions, and business intuition questions.

 

Structuring questions

 

These questions present a scenario or problem and ask candidates to identify the most helpful option or the type of information that should be gathered.

 

Examples include:

 

  • Which of the following would be most helpful?

Basic business knowledge you should be familiar with include: supply and demand, market size and market shares, pricing strategies, competitive advantage, synergies, profitability, and supply chain dynamics to name a few concepts.

 

How is the BCG Online Case / Chatbot Interview Scored?

 

The BCG online case or chatbot interview is scored based on a points system. 3 points is awarded for a correct answer and 1 point is deducted for an incorrect answer. Therefore, unless you are able to confidently eliminate at least two or three answer choices, it is better to leave a question blank than to guess.

 

In addition to an overall score, the BCG online case or chatbot interview also assesses several specific criteria: problem solving skills, analytical and quantitative capabilities, business acumen, critical thinking and decision-making, communication and presentation skills, and time management and adaptability.

 

While BCG does not disclose official scoring mechanisms of these criteria, we can make an educated guess on how they are scored:

 

  • Problem solving skills: This is likely assessed based on your answers to the numerical short-text freeform. Quantitative problems usually have a single correct answer, which you will need to submit correctly

 

  • Analytical and quantitative capabilities: This is likely assessed based on your answers to the numerical short-text freeform. Math calculations have a single correct answer, which you will need to submit correctly

 

  • Business acumen: This is likely assessed based on what answers you select for the single-select multiple choice questions, multiple-select multiple choice questions, and long-text freeform

 

  • Critical thinking and decision-making: This is likely assessed based on what answers you select for the single-select multiple choice questions as well as how long it takes you to select an answer

 

  • Communication and presentation skills: This is likely assessed in the final self-recording where you present your final recommendation or solution to the case. There may be a manual review of your recording or an AI algorithm may score your presentation

 

  • Time management and adaptability: This is likely assessed based on whether you have answered every single question

 

Remember that you are assessed holistically. If you are a lacking a bit in one of these areas, you can make up for it with a strong performance in another area. Therefore, you do not need to be absolutely perfect on the BCG online case or chatbot interview in order to pass it.

 

BCG Online Case / Chatbot Interview Examples

 

BCG provides four sample questions on the BCG online case website. We’ve list them below and also provided you with step-by-step answers on how to solve each one.

 

BCG Online Case / Chatbot Interview Question #1

 

BCG online case chatbot interview question #1


Solution: To calculate the average gross margin, we need to calculate the weighted average of profit margins of the three types of gasoline. We know that each type of gasoline has a profit of €0.10 and we know the percentage of sales that each type of gasoline accounts for.

 

Therefore, the average gross margin can be calculated as:

 

Average gross margin = [(0.3)*(0.1/1.7)] + [(0.4)*(0.1/1.6)] + [(0.3)*(0.1/1.5)]

 

Average gross margin = 0.0626

 

The correct answer is 6.3%.

 

BCG Online Case / Chatbot Interview Question #2

 

BCG online case chatbot interview question #2


Solution: The market study on the right shows the supply and demand of gasoline. To find the price point that maximizes profit, we need to find where these two curves intersect. This happens just below the price point of €1.70.

 

Among the answer choices, the choice that is closest to the correct answer is €1.70

 

BCG Online Case / Chatbot Interview Question #3

 

BCG online case chatbot interview question #3


Solution: From the industry research table, we see that the average retail sales per car (€) does not change based on the gasoline price. Therefore, we just need to pick the gasoline price that gets us the highest number of cars buying from the gas station each week.

 

Therefore, the correct answer is €1.5.

 

BCG Online Case / Chatbot Interview Question #4

 

BCG online case chatbot interview question #4


Solution: To determine the price the company should charge for gasoline to maximize combined profits, we need to calculate profits from gasoline and from retail sales for each of the four price points.

 

For 1.5€/L

 

  • Retail profit = (130 * €10) * 0.3 = €390

 

  • Gasoline profit = €0 (sold at cost)

 

  • Total profit = €390

 

For 1.6€/L

 

  • Retail profit = (90 * €10) * 0.3 = €270

 

  • Gasoline profit = 90 * (€0.1 * 130) = €1,170

 

  • Total profit = €1,440

 

For 1.7€/L

 

  • Retail profit = (60 * €10) * 0.3 = €180

 

  • Gasoline profit = 60 * (€0.2 * 100) = €1,200

 

  • Total profit = €1,380

 

For 1.8€/L

 

  • Retail profit = (40 * €10) * 0.3 = €120

 

  • Gasoline profit = 40 * (€0.3 * 60) = €720

 

  • Total profit = €840

 

Therefore, the correct answer is 1.6€.

  • Format: The BCG online case is conducted through a chatbot interface, simulating a conversation format, whereas the traditional BCG case interview involves face-to-face interaction with a human interviewer

 

  • Interaction complexity: The BCG online case may present challenges related to interface complexity, as candidates have to navigate a digital platform with specific functionalities and limitations. Traditional interviews, on the other hand, are more straightforward in terms of interaction

 

  • Time pressure: The BCG online case imposes more stringent time constraints, with constant reminders of the remaining time and automatic cutoffs for certain sections. This intensifies the time pressure compared to traditional interviews where the interviewer is responsible for making sure the case is completed on-time

 

  • Real-time feedback: For a traditional BCG case interview, the interviewer provides feedback and guidance throughout the process, allowing candidates to adjust their approach. However, in the BCG online case, there is no real-time feedback, which could potentially impact the candidate's performance

 

  • Tools allowed: For the BCG online case, candidates are permitted to use calculators and other resources. This is not the case for traditional BCG case interviews where candidates must rely solely on themselves

 

  • Question types: The BCG online case includes a variety of question formats such as multiple choice, freeform text, and video responses, whereas traditional case interviews consist of verbal interaction and discussions

 

  • Evaluation criteria: The BCG online case places more emphasis on evaluating quantitative and analytical skills given that it is more difficult to evaluate soft skills online. The quantitative problems on the BCG online case tend to be more difficult than a traditional case interview since you are allowed to use a calculator
