Sample Casey Conversation Flow

Here's a realistic example of how Casey might introduce and develop a case:

Casey: "Hi there! I'm Casey, BCG's AI interviewer. I'm excited to work through a business case with you today. Before we dive in, could you tell me briefly about your background and why you're interested in consulting?"

Your Response: "Hi Casey! I have a background in engineering and have been drawn to consulting because I enjoy solving complex problems and helping businesses improve their operations. I'm particularly interested in BCG's collaborative approach to transformation."

Casey: "Great! Your engineering background will definitely be valuable. Let's jump into our case. Our client is MegaRetail, a large grocery chain with 500 stores across the US. Their CEO is concerned because profits have declined 15% over the past two years, despite relatively stable revenues. She's asked BCG to help identify the root causes and develop a turnaround plan. What would be your initial approach to this problem?"

This natural conversation style requires you to think and communicate just as you would with a human interviewer.

The Casey Success Framework

1. Master Conversational Case Solving

Unlike traditional case interviews where you can pause to think, Casey expects flowing conversation. Practice thinking out loud and structuring responses conversationally.

Effective Casey Response: "Thanks for the context, Casey. To tackle MegaRetail's profit decline, I'd like to structure my analysis around three main areas: revenue trends, cost increases, and operational efficiency changes. Before diving deeper, could you tell me more about the competitive landscape—are other grocery chains experiencing similar challenges?"

2. Ask Strategic Questions

Casey rewards curiosity and business acumen through your questions. Focus on clarifying questions that demonstrate consulting thinking.

High-impact question types:

Market context: "How has the grocery industry performed overall during this period?"
Competitive dynamics: "Have new competitors entered MegaRetail's key markets?"
Operational changes: "Has MegaRetail made any significant changes to their business model recently?"
Data availability: "What specific financial and operational data do we have access to?"

3. Structure Responses Clearly

Even in conversational format, Casey evaluates your ability to think structurally. Use MECE principles while maintaining natural conversation flow.

Structured Casey Response: "Based on the data you've shared, I see three potential drivers of the cost increases: First, supply chain disruptions affecting procurement costs; Second, labor cost inflation in key markets; Third, inefficient store operations due to aging infrastructure. Should we prioritize investigating the supply chain impact first, given its potential magnitude?"

4. Demonstrate Business Judgment

Casey tests your practical business sense through follow-up questions and scenario evaluation. Show you understand real business constraints and trade-offs.

5. Adapt to Casey's Cues

Pay attention to Casey's responses and adjust your approach accordingly. If Casey provides specific data, incorporate it meaningfully. If Casey seems to redirect, follow the new direction while maintaining your analytical thread.
