In February 2024, Boston Consulting Group (BCG) introduced a new cognitive assessment in several of its global offices, including Germany – the BCG Cognitive Test. This strategic move, anticipated to expand worldwide, marks a significant shift in how potential consultants are evaluated, and a move away from the BCG Casey Chatbot Test.

The introduction of the BCG Cognitive Test is a direct response to the increasing challenges in maintaining the integrity of remote assessment processes, particularly with the advent of advanced AI tools like ChatGPT.

This article explores the intricacies of the new test, its implications for candidates, and effective preparation strategies.

The Genesis of the BCG Cognitive Test

A Response to Modern Challenges

In the ever-evolving landscape of consulting recruiting, the integration of technology into the recruitment process has both streamlined operations and introduced new challenges. One significant hurdle has been the advent of advanced AI technologies, such as ChatGPT, which candidates have increasingly turned to for assistance in solving traditional test questions. This trend not only raises concerns about the fairness and integrity of the assessment process but also calls into question the authenticity of a candidate’s abilities.

With the new abilities of AI to analyze screenshots directly, candidates would have been able to copy the test prompt (including charts and quantitative information) from the BCG Casey into the AI prompt and automatically create the answer.

In response to these challenges, BCG embarked on a journey to revamp its assessment approach, leading to the birth of the BCG Cognitive Test in early 2024. This strategic decision was driven by the necessity to ensure a level playing field for all candidates, irrespective of their access to or familiarity with AI technologies.

By focusing on numerical and logical skills in a tightly timed and proctored environment, BCG aims to more accurately gauge a candidate’s innate problem-solving abilities and intellectual agility – qualities that are paramount in the fast-paced world of consulting.

Global Rollout Plans of the BCG Cognitive Test

We believe that BCG’s introduction of the Cognitive Test in a few select offices, such as those in Germany, marks the beginning of a broader strategy aimed at global implementation. This phased rollout reflects the firm’s commitment to maintaining a high standard of candidate evaluation across all its locations worldwide.

By standardizing the assessment process, BCG ensures that every potential consultant, regardless of geographic location, is evaluated using the same criteria, thereby upholding the principles of fairness and equality.

The global rollout of the BCG Cognitive Test is not just an operational update; This move reinforces the ambition of all MBBs to position hire meritocratically where talent and capability are the sole determinants of a candidate’s success.

Other test formats such as the BCG one-way video interview or the BCG Pymetrics are likely not affected and will be continued.

Understanding the Test’s Framework

Proctored Online Format

The BCG Cognitive Test represents a significant leap in ensuring the integrity of the assessment process through its proctored online format. Candidates are required to undertake the test in a monitored environment, facilitated by the video conferencing tool Zoom.

Proctors oversee the examination in real-time, ensuring that candidates adhere to the rules and that the test’s authenticity is preserved. This method effectively counters the potential for unfair advantages, such as the use of unauthorized resources or AI tools, maintaining the credibility of the evaluation process.

Numerical and Logical Skills Assessment

At the heart of the BCG Cognitive Test is its focus on numerical and logical skills assessment. This component is designed to probe the candidate’s quantitative reasoning abilities, a cornerstone of effective problem-solving in the consulting realm.

Through a series of tailored questions, BCG evaluates an individual’s capacity to analyze data, discern patterns, and derive logical conclusions under pressure. These skills are indispensable for consultants who are often tasked with navigating complex business challenges and delivering data-driven insights to clients.

The test’s emphasis on quantitative reasoning aligns with the critical competencies required for success in the consulting industry, ensuring that candidates possess the intellectual rigor necessary for high-stakes decision-making.

Rigorous Question Pacing in the BCG Cognitive Test

One of the most distinguishing features of the BCG Cognitive Test is its rigorous question pacing. With 80 questions to be completed in a mere 30 minutes, the test sets a brisk pace that demands quick thinking and sharp analytical skills.

This design is intentional, aiming to simulate the pressure-cooker environment of consulting work, where consultants must often make rapid, yet accurate, assessments. The tight time constraint also makes it virtually impossible for candidates to seek external assistance, including the use of AI technologies like ChatGPT.

This constraint ensures that the focus remains on the candidate’s own abilities, testing their genuine analytical prowess and time management skills. The pacing of the test is not just a challenge; it’s a deliberate barrier to cheating on the test.

Insight into Question Types

Quantitative Reasoning Focus

The BCG Cognitive Test places a significant emphasis on quantitative reasoning, a critical skill set for consultants who must navigate complex data, financial analyses, and strategic decision-making processes. This focus is designed to measure a candidate’s ability to understand, interpret, and analyze quantitative information effectively. It challenges candidates to demonstrate their proficiency in numerical analysis, logical reasoning, and problem-solving under pressure.

The questions are crafted to reflect real-world business scenarios, requiring candidates to apply mathematical concepts and analytical skills in a practical context. This approach ensures that the test not only assesses raw numerical ability but also evaluates how candidates can leverage their quantitative reasoning skills to solve complex problems.

By emphasizing quantitative reasoning, BCG aims to identify individuals with the intellectual agility and analytical prowess essential for succeeding in the demanding consulting environment.

Sample Question of the BCG Cognitive Test

Let’s dissect a sample question from the BCG Cognitive Test to understand the type of logical reasoning it demands:

If Lisa was twice as old as Sam when he was 5, and Sam is 35 now, how old is Lisa?

Sample question of the BCG Cognitive Test

This question exemplifies the cognitive test’s focus on numerical and logical reasoning. It requires candidates to process given information and apply arithmetic operations alongside logical deductions to solve the problem.


  • Understanding the Scenario: The question informs us about the ages of Lisa and Sam at a specific point in their past and provides Sam’s current age.
  • Identifying the Relationship: When Sam was 5 years old, Lisa was twice his age, meaning Lisa was 5 * 2 = 10 years old at that time. The difference in their ages, therefore, is 10 – 5 = 5 years.
  • Calculating the Age Difference: The key information is that Lisa is 5 years older than Sam. This age difference remains constant over time.
  • Applying Logical Reasoning: Knowing Sam’s current age is 35 and that Lisa is consistently 5 years older than Sam, we can calculate Lisa’s current age. Thus, Lisa is 35 (Sam’s age) + 5 (the age difference) = 40 years old.

This sample question from the BCG Cognitive Test showcases the examination’s demand for a blend of numerical calculation and logical reasoning. It challenges candidates to carefully analyze the information, apply basic arithmetic principles, and deduce the correct answer based on a logical understanding of age differences and time progression.

You might also notice that the question is not overly complex in itself. However, imagine going through 80 questions, only with a couple of seconds to think about each.

The ability to navigate through such questions efficiently requires practice in both quantitative reasoning and critical thinking, underlining the importance of preparation strategies that focus on these skills.

Preparation Strategies

Leveraging GMAT and Bain SOVA Resources

To excel in the BCG Cognitive Test, candidates should focus on sharpening their quantitative reasoning skills. A strategic approach to preparation involves leveraging resources that closely mirror the test’s focus and format. Two highly recommended resources are GMAT study materials and the Bain SOVA guide.

  • GMAT Study Materials: The Graduate Management Admission Test (GMAT) is known for its rigorous quantitative section, which tests a wide range of mathematical skills and problem-solving abilities. GMAT prep books and online resources offer a wealth of practice questions that require similar analytical thinking and numerical proficiency. Specifically, the GMAT’s quantitative reasoning section can help candidates familiarize themselves with the types of numerical and logical puzzles they might encounter on the BCG Cognitive Test.

Incorporating these resources into your preparation regimen can provide a solid foundation in quantitative reasoning, enhance your problem-solving strategies, and improve your ability to perform under tight time constraints.

Understanding the Test’s Unique Challenges

The BCG Cognitive Test presents a unique set of challenges that distinguish it from other industry assessments, such as the Casey and traditional case interview formats. Understanding these differences is crucial for effective preparation and success:

  • Tighter Time Constraints: With 80 questions to answer in just 30 minutes, the BCG Cognitive Test imposes considerably tighter time constraints compared to other assessments. This format requires quick thinking and efficient problem-solving, as candidates have less than 30 seconds per question. Time management skills become as critical as solving skills, emphasizing the need for practice under similar conditions to improve speed and accuracy. As is often the case with such tightly-timed assessments, we don’t think it is expected that you will actually be able to go through all questions. The goal should be to go through as many questions as possible and answer them accurately. If you are stuck in a question for too long, move on!
  • Departure from Case Interviews: Unlike the Casey or traditional case interviews that focus on situational analysis and strategic thinking in business scenarios, the BCG Cognitive Test emphasizes quantitative reasoning and logical skills. This shift means candidates must prepare differently, focusing more on numerical analysis and less on case study preparation.
  • Increased Difficulty Level: The combination of a strict time limit and the requirement for precise analytical thinking makes the BCG Cognitive Test more challenging than many other assessments in the consulting field. It tests not only a candidate’s ability to solve quantitative problems but also their capacity to maintain composure and perform under pressure.

Practice with time-bound quantitative reasoning questions, familiarize yourself with rapid problem-solving techniques and develop strategies for managing stress and maintaining focus throughout the test. Emphasizing speed, accuracy, and mental agility in your preparation will be key to mastering the BCG Cognitive Test.
