How Market Sizing Practice Works

1. Real Interview Simulation
AI interviewer behaves like a real MBB partner - no over-helping, realistic constraints
2. Ask Clarifying Questions
Get case-specific data when you ask, or hear "I don't have that information"
3. Comprehensive Evaluation
Tier-based scoring (Top 0.1% to 20%) with specific, actionable feedback
