Management Consulting Interview: McKinsey, BCG, Bain

Consulting Interview Guide: MBB and Big Four

Management consulting interviews at McKinsey, BCG, Bain (MBB), and Big Four firms (Deloitte, PwC, EY, KPMG) center on case study interviews and behavioral fit rounds. The acceptance rate at MBB firms is approximately 1-2%, making them among the most selective employers globally.

Consulting case interviews test three skills: structured problem decomposition, quantitative analysis under pressure, and executive-level communication. The best candidates think in frameworks but adapt them to each unique case.

Case Interview Frameworks

• Profitability — Revenue × Volume - Fixed Costs - Variable Costs. The most common case type
• Market Entry — Market size, competitive landscape, capabilities, entry barriers
• M&A — Standalone value + synergies - integration costs
• Pricing — Cost-based, value-based, competition-based approaches
