Big 4 consulting interviews are built on a single principle: Can you break down ambiguous, high-stakes business problems into structured hypotheses and back them with data? You need to think in margins, market dynamics, and operational levers — and articulate your reasoning under real-time interview pressure.
Big 4 Interview gives you that practice. Our AI coach challenges you with realistic case scenarios — from profitability crises to market entry strategies — and gives you structured feedback on your hypotheses, quantitative reasoning, and executive-level recommendations.
How it works

- Get AI-powered feedback on your case frameworks, hypothesis trees, and data-driven reasoning

Why Big 4 interviews need dedicated prep
Big 4 case interviews test whether you can decompose messy business problems into clean, testable hypotheses. Generic case prep misses the specific evaluation criteria: deep quantitative reasoning, multi-level issue decomposition, and the ability to challenge assumptions while staying grounded in data.
Our AI doesn't accept surface-level answers. It challenges your hypotheses, forces you to defend your numbers, and pushes you to think through second-order effects and real business tradeoffs — exactly what consultants at Deloitte, PwC, EY, and KPMG are evaluating when they score your cases.
Built for aspiring consultants
Whether you're targeting associate consultant roles at any of the Big 4, transitioning from finance or operations into consulting, or preparing for senior consulting leadership positions, Big 4 Interview helps you build the structured problem-solving and business judgment skills that define successful consulting careers.
