Mastering the BCG Online Test: A Comprehensive Guide to the Casey Chatbot
Want to ace the BCG Online Test? Discover insider insights, time management hacks, and the best prep resources for guaranteed success!
The BCG Online Test is a critical part of Boston Consulting Group’s hiring process. Unlike traditional case interviews, this assessment is conducted entirely through the Casey Chatbot, a digital tool designed to simulate real consulting problems. Candidates must navigate business scenarios, analyze data, and provide well-structured responses—all within a timed, interactive environment.
If you're preparing for this test, understanding its format, question types, and evaluation criteria is essential. In this guide, you'll learn how the BCG Online Test works, what skills it assesses, and strategies to help you succeed.
What is the BCG Online Test?
This test is a chatbot-driven case interview where you interact with Casey, an AI-based system, instead of a live interviewer. Over 25 to 30 minutes, you will respond to a series of questions designed to evaluate your analytical, problem-solving, and communication skills.
Unlike traditional case interviews, where you can clarify questions or adjust your approach based on interviewer feedback, the Casey Chatbot strictly follows a scripted format. That means your ability to interpret data, structure your responses, and communicate clearly is more important than ever.
Structure of the BCG Online Test
The assessment consists of a mix of multiple-choice, short-answer, and video response questions.
-
Multiple-choice questions: Typically involve numerical reasoning, logical reasoning, or data interpretation.
-
Short-answer questions: Require you to explain your reasoning concisely, often involving calculations or structured insights.
-
Video response questions: Ask you to verbally summarize your findings and recommendations within a limited time.
Each section is timed, making time management a crucial factor in your performance.

How to Prepare for the BCG Online Test
Even though the assessment is designed to evaluate your natural abilities, preparation is key to maximizing your performance.

-
Typing concise but structured answers to short-answer questions

Interpreting data quickly under time constraints
