Any help how to prepare myself for BCG online assessment?

Hey, congratulations on the invitation! Here are my two cents:

BCG Online Case / Casey Chatbot

This is the core part for most people and feels like an automated business case.

What to Expect:

• Duration: 25–35 minutes
• Format: Chatbot-led questions (text and multiple choice)
• Topics: Business problems — usually around profitability, market entry, M&A
• Tasks:
   
  • Reading exhibits (graphs, tables, charts)
  • Performing mental math
  • Making logical deductions
  • Answering structured questions

How to Prepare (Especially Without Business Background)

1. Get Comfortable with Case Concepts:
    
   • Profit = Revenue – Cost
   • Market sizing basics
   • Breakeven and ROI concepts
   • Reading graphs quickly and extracting insights
      
2. Practice with Free Resources:
    
   • BCG Casey Simulation (if you were invited)
   • PrepLounge chatbot case simulations
   • Victor Cheng’s Case Interview Math drills
   • Look for mock BCG online tests online (many YouTube videos simulate it)
      
3. Brush Up on Data Interpretation and Business Math:
    
   • Percentages, growth rates, ratios
   • Estimation and fast calculations
   • Use GMAT-level Data Sufficiency and Problem Solving questions
      
4. Practice Thinking Aloud & Structuring:
    
   • Although it’s not a live case, structure your thoughts logically
   • Practice summarizing charts into 1–2 sentence insights

Quick Tips

• Time is tight → don’t spend too long on one question
• Use paper for quick calculations
• Look for trend shifts or outliers in charts
• Eliminate clearly wrong answers if stuck
• Don’t panic — many candidates without business backgrounds still pass!

Hi Jasmine,

Q: Could anyone explain the structure of the assessment, how to best prepare for it, and possibly recommend any materials or tips for success? 

I provided some information below on the assessment.

The BCG Online Case (also called Hirequotient or Casey Chatbot Interview) is an 8-10 question test that BCG now uses in several countries. It is structured in two parts:

• 8-10 questions to be taken in 35 minutes (in its new version, before it was 25-30 minutes)
• 1 video interview question at the end, where you usually have to provide a recommendation

If you want to prepare further for the online case, I created a software simulation that replicates the chatbot and one-way video interview.

It includes the following and more:

• 4 Casey Software Simulations of the Chatbot. These are live chatbots simulating exactly the same chatbot environment of the test (meaning you will receive questions from an actual chatbot with a flow equivalent to the one of the test).
• 4 One-Way Video Interviews. These come with Artificial Intelligence reports, so that you can see how the software will perceive your performance in terms of voice, speech clarity, energy and more.
• 2 PDF Simulations of the Chatbot. These are additional tests Casey-style, meaning you will have 6 different Casey Chatbots to train with overall.
• Free access to 6 PSTs and Potential Tests for further practice.
• Deep explanation of all the 5 types of questions asked in the BCG Online Case thanks to the complimentary 144-page guide.

Good luck!

I see you've received a great answer already, so let me just add a resource you might find useful as you practice for these tests:
