What Is the BCG Online Case?

The BCG Online Case is an online case interview simulation that assesses a candidate’s problem-solving skills and analytical thinking abilities. It is designed to simulate a real-life client engagement, and consists of a single case study that the candidate must work through.

The case study typically involves a business situation where the candidate must analyze data, identify key issues, and propose solutions. The case may fall into one of several categories, such as:

1) Market entry strategy;
2) Pricing optimization;
3) Cost reduction; or
4) Growth strategy.

The duration of the BCG Online Case test ranges from 25 to 30 minutes, depending on the number of questions involved (normally 6-8 questions). Candidates are given a set of materials, including charts, graphs, and other data, and must use this information to answer a series of questions.

While time management is important, the focus should be on demonstrating strong analytical and problem-solving skills. BCG is more interested in the quality of your thought process and the insights you generate than in how quickly you complete the case.

What Does the BCG Online Case Test For?

The BCG Online Case bot is designed to test a candidate’s analytical and problem-solving skills in a simulated consulting environment. Specifically, it assesses the following key areas: 

  1. Structured Thinking: The ability to break down complex problems into smaller, manageable components and develop a clear, logical approach to solving them. 

  2. Data Analysis: The capacity to quickly and accurately interpret data from various sources, such as charts, graphs, and tables, and draw meaningful insights from them. 

  3. Business Acumen: An understanding of key business concepts and the ability to apply them to real-world situations.

  4. Creativity: The ability to generate innovative solutions and think outside the box when faced with challenging problems.

  5. Time Management: The ability to efficiently manage time and prioritize tasks to complete the case within the given timeframe.

  6. Adaptability: The flexibility to adjust one’s approach in response to new information or changing circumstances.

  7. Attention To Detail: The ability to carefully review and consider all relevant information when making decisions and recommendations. 

How To Prepare For the BCG Online Case

Refining your problem-solving skills is essential for achieving success in the BCG Online Case experience. One of the most effective ways to develop these skills is by practicing mock case interviews. Engaging in these practice sessions helps you hone your ability to structure complex problems and devise logical solutions. 

Every case interview includes structuring questions, which are critical to demonstrating your analytical prowess. For example, at the beginning of a case, you might be asked to develop an issue tree to break down the problem into manageable components. Throughout the case, you may encounter brainstorming questions such as, “Which factors influence market growth?” These questions test your ability to think strategically and comprehensively. 

Practicing case interviews can be done independently, with friends, or with the guidance of an expert. Each method offers unique benefits: 

  • Independent Practice: Allows you to work at your own pace and focus on specific areas where you need improvement. 
  • Practicing with Friends: Provides the opportunity to simulate a more realistic interview environment and receive feedback from peers. 
  • Expert Guidance: Offers professional insights and tailored advice to help you refine your approach and address any weaknesses. 

By diligently refining your problem-solving skills through structured practice, you can significantly improve your chances of success in the BCG Online Case experience.

Type of BCG Online Case Interview Questions

1. Structuring/Information 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. While they may appear data-focused, they require candidates to employ structuring techniques and create an issue tree. 

Every BCG online case starts with a structuring or information question, such as: 

  • Which of the following would be most helpful? 
  • What statistics about ABC should the team gather? 
  • Which piece of information would help ECG move forward with the project? 

To approach these questions, carefully read the provided options and mentally construct an issue tree based on the available choices. Select options that collectively cover the issue tree and address the various components of the problem, demonstrating critical thinking, analysis, and the ability to identify relevant information. 

2. Quantitative Questions

Each case typically includes approximately two quantitative/mathematical questions, usually presented in a short text answer format or occasionally as single-select multiple-choice questions. 

Most quantitative questions are accompanied by an exhibit with around 20 data points, some of which may be extraneous. Knowledge of accounting or finance is not necessary, as the calculations and formulas are generally straightforward, involving concepts such as weighted averages, probabilities, and compound percentages. Practicing these types of problems can enhance performance. 

The follow-up question can indicate whether your answer is correct. If asked to elaborate on your reasoning, your response is likely correct. If prompted to address specific calculations or smaller steps, your initial attempt may have been incorrect. 

3. Critical Thinking & Logical Questions

These questions assess your ability to analyze a scenario, apply logical reasoning, and make informed judgments. They often involve evaluating different courses of action, determining cause-and-effect relationships, or identifying the most logical conclusion based on the provided information.

Pay attention to the wording and any qualifiers that indicate how airtight the logic needs to be. For example, “Which of the following courses of action would LIKELY MAKE you more rich?” has a weaker qualifier than “Which of the following courses of action would CERTAINLY MAKE you more rich?” 

Consider relevant factors, constraints, or specific conditions mentioned in the question when evaluating the options. 

4. Intuition/Insight Questions

These questions are highly popular but challenging to master. They require you to generate or select a range of insights, elements, or factors based on a given context. The specific insights can vary significantly, encompassing root causes, effects, solutions, and more. 

Examples of intuition or insights questions include: 

  • What are some personal expenses that tend to increase after getting married?
  • How can one become more disciplined in saving money? 
  • What are effective talking points to persuade a life partner to reduce spending on clothing? 
  • What are potential reasons for the underperformance of the stock market in the past six months? 
  • In what situations would one need to utilize an emergency fund? 

These questions demand thoughtful analysis and the ability to derive meaningful conclusions based on given scenarios. Diligent practice is essential to improve in this area.

Scoring Criteria

In the BCG online case chatbot, the selection of candidates is not solely based on the accuracy of their answers but also on their approach to problem-solving and their ability to break down complex issues. Candidates are required to provide an answer for each question to progress to the next one, leaving no choice but to make an educated guess even when unsure of the correct response. 

While BCG does not disclose official information regarding the evaluation criteria, insights can be gathered from the BCG Interactive Case Library. The majority of criteria focus on the problem-solving aspect of the consulting role: 

  1. Problem-Structuring
    Candidates are evaluated based on their problem-structuring skills, which involve approaching problems in a structured and mutually exclusive, collectively exhaustive (MECE) manner. The test also assesses the candidate’s ability to gather data and test hypotheses during the problem-solving process. Demonstrating strong analytical and problem-solving capabilities is crucial for management consultants.

  2. Qualitative and Quantitative Processing
    The BCG chatbot Test evaluates candidates’ math and analytical skills, specifically their ability to analyze and process both qualitative and quantitative information within the case. The test assesses their proficiency in performing relevant mathematical calculations, with an emphasis on common business-world calculations such as percentages, averages, and working with large numbers. The objective is to determine how effectively candidates can apply these processing skills to the given scenarios and derive meaningful insights. 
  1. Business Intuition
    Candidates’ business intuition is another trait assessed in the BCG Online case. The test focuses on their capacity to evaluate potential costs and benefits, make informed decisions, and provide sound conclusions and recommendations based on their business knowledge and experience. The goal is to determine how well candidates can apply their business intuition to complex scenarios and provide relevant insights and directions tailored to the specific business context presented in the case. 
  1. Data Synthesis & Interpretation: Lastly, the BCG chatbot interview assesses candidates’ aptitudes for data synthesis and interpretation. This involves their proficiency in summarizing and synthesizing all relevant information to derive viable solutions for the client. The test measures their ability to draw meaningful conclusions from data, adopting a hypothesis-driven mindset. Candidates are expected to either incorporate their conclusions into existing hypotheses or generate new hypotheses that are relevant to the case at hand. The objective is to assess candidates’ ability to analyze and interpret data effectively to make informed decisions and provide valuable insights to the client.
