AI-Powered Case Interview Training
CaseBuddy is an AI-powered interview preparation platform that simulates real consulting case interviews. Practicing with Sarah โ our AI Business Consultant โ users experience realistic, conversational case sessions across Market Sizing, M&A, Profitability, Market Entry, Growth Strategy, and Operations.
The platform is built for students and early-career professionals targeting roles at McKinsey, BCG, Bain, and other top-tier consulting and strategy firms. Unlike static prep resources, CaseBuddy adapts in real-time โ asking clarifying questions, providing structured hints, and delivering actionable post-interview feedback.
CaseBuddy operates on a freemium SaaS model with a consumer subscription. Free users get daily practice interviews; Premium subscribers ($9.99/month or $99.99/year) unlock unlimited daily sessions and priority access to new features including industry-specific case scenarios.
Egor brings a rare combination of strategic consulting intuition and hands-on engineering depth. He spent a year as a Research Assistant at McKinsey & Company and went on to build data infrastructure at Rocket Internet and Tesla before founding CaseBuddy in 2025.
Our interactive case interviews are best optimized for desktop experiences.
iOS and Android apps are coming soon!
