Free Business Case Study Samples For Consulting Interview Preparation
Case interviews are a critical component of the hiring process at top management consulting firms such as McKinsey, BCG, and Bain. These interviews present candidates with business problems that must be analyzed and solved using structured thinking, quantitative reasoning, and business knowledge. Fortunately, numerous resources offer free case study samples to help candidates prepare effectively. This article explores the various sources of free business case samples, their types, frequency in actual interviews, and how candidates can access them to enhance their preparation.
Understanding Case Interviews in Management Consulting
Case interviews simulate the type of work management consultants perform for clients, requiring candidates to analyze business situations, identify problems, develop solutions, and make recommendations. These interviews typically involve a verbal dialogue between the candidate and interviewer, where candidates must think aloud, structure their approach, and justify their reasoning.
The provided source material indicates that case interviews are used across major consulting firms and vary in type and complexity. According to the data, some of the most common case types include profitability cases, investment cases, market sizing questions, market expansion cases, industry analysis, pricing cases, and acquisition cases. Understanding these different case types and practicing with relevant samples is essential for interview preparation.

Many top consulting firms provide free case interview examples on their official websites, offering candidates direct insight into the types of problems they might encounter during actual interviews.

Free Case Study Resources from Universities and Organizations
Several universities and organizations offer free or open access to business case studies that can be valuable for consulting interview preparation. These cases are typically free to use, share, and reuse for teaching purposes.
University-Based Collections
Boston University, for example, provides access to business case studies through its library system. The university recommends core collections as the best starting point for most teaching needs, with additional specialized resources available for specific areas like ethics, leadership, sustainability, Indigenous business, statistics, or research.
Specialized Case Collections
The CLEO (Center for Employee Ownership) Collection offers free case studies of employee-owned companies. These cases provide insights into unique business structures and governance models. Examples include:
- A study on HDR, a large multinational professional services firm with broad-based employee ownership
- A study on Friesens Corporation, a leading Canadian book printer with employee ownership
These specialized cases can be particularly valuable for candidates interested in alternative business models or industries with unique operational challenges.
Types of Case Studies and Their Frequency in Interviews
Understanding the types of case studies that appear most frequently in actual consulting interviews can help candidates prioritize their preparation. According to the source material, analysis of 253 case studies from business school case books reveals the following distribution:
- Profitability cases (29% of cases)
- Investment cases (19% of cases)

- Other types (37% of cases)
Based on this distribution, candidates preparing for six case interviews during a typical recruitment process can reasonably expect to encounter:

This information allows candidates to allocate their preparation time according to the likelihood of encountering different case types.

- Profitability cases: Focus on identifying the reasons for changes in profitability and developing solutions.
- Market expansion cases: Involve entering new markets, segments, or geographies.
