Case Interview Styles by Firm

If you are preparing for consulting interviews, understanding how each firm structures its case process is one of the biggest competitive advantages you can have. Many candidates assume that all consulting interviews are the same, but the reality is that each firm approaches case interviews differently.

While every consulting interview will test your ability to structure problems, analyze data, and communicate insights clearly, the style, pacing, and expectations vary across firms. McKinsey uses interviewer-led cases focused on logical reasoning. Bain emphasizes practical recommendations and business judgment. BCG often favors open-ended, conversation-style discussions.

This section is your complete guide to how every consulting firm runs its case interviews, starting with MBB and expanding across the broader consulting landscape.

What You Will Learn

We will begin with the major strategy firms—McKinsey & Company, Boston Consulting Group (BCG), and Bain & Company—and analyze what makes each of their interview formats unique. From there, you will find detailed breakdowns of other consulting categories, including:

  • Strategy Consulting Firms: OC&C Strategy Consultants, LEK Consulting, Oliver Wyman, Roland Berger
  • Management Consulting Firms: Deloitte Consulting, EY-Parthenon, Accenture Strategy, PwC Strategy&
  • Private Equity Consulting Firms: Alvarez & Marsal, Teneo, Investor Group Services (IGS)
  • Economic Consulting Firms: Analysis Group, Cornerstone Research, NERA Economic Consulting
  • Restructuring and Financial Consulting Firms: FTI Consulting, AlixPartners
  • Technology Consulting Firms: IBM Consulting, Capgemini Invent, Slalom Consulting
  • Healthcare Consulting Firms: ZS Associates, Simon-Kucher, ClearView Healthcare Partners

Each firm profile covers the interview structure, types of case questions, skills assessed, and tips from successful candidates. The goal is to help you understand exactly what to expect and how to tailor your preparation to each firm’s priorities.

Why Firm-Specific Preparation Matters

Two candidates can have similar casing skills yet perform very differently depending on the firm. McKinsey values clarity and logical flow. Bain rewards practical, results-driven problem solving. BCG looks for structured creativity and comfort with ambiguity.

By studying each firm’s case interview process, you can focus your preparation where it matters most. This transforms your approach from general case practice to targeted, firm-specific strategy, which is often the difference between a good performance and a standout one.
