Bain Case: Old Winery

You have inherited the “Old Winery” from your grandfather, a winery that has been family-owned for five generations and can be dated back to the 16th century. Half of the eleven hectares are used to grow white grapes, the other half to grow red grapes. They are grown in a conventional way, i.e. they are not organically farmed and certified. The vine stocks are in a good condition regarding age and care. Overall, the only ¼ of the harvest is made into wine by the winery itself; the rest is sold. Your grandfather never wanted to change the image of the winery and left the managerial and administrative task to a young and energetic wine-maker. Due to the not so well-known brand, the demand for the “Old Winery” wine is currently rather low. You do not intent to run the winery operatively, given your limited knowledge of winemaking, but find the idea of owning a winery exciting.

Nordhavn Seafood (McKinsey)

CLIENT OBJECTIVE Our client, Nordhavn, a Norwegian seafood company, wants to know whether it should acquire Patagonia Salmon, a family-owned salmon farmer in southern Chile. BACKGROUND INFORMATION Nordhavn farms Atlantic salmon in Norway's fjords and sells it fresh and frozen across Europe and Asia. Farming sites in Norway are limited by regulation and expensive to obtain, so Nordhavn's growth at home has stalled. Chile is the world's second-largest salmon producer, with lower costs in some areas, but the industry has a history of biological crises: algal blooms, sea lice and a virus outbreak that once destroyed a large part of the country's production. Patagonia Salmon owns hatcheries, sea farming sites and a processing plant in the Los Lagos and Aysén regions. It sells fresh fillets by air to the US and Brazil and frozen products to Asia. The founding family wants to sell, and Nordhavn has been invited to bid.

GlobalAccess Health – Funding the Next Million Diagnoses

GlobalAccess Health (GAH) is a UK-based international non-profit focused on tuberculosis (TB) and other infectious diseases. It develops and distributes low-cost diagnostic tests to public clinics, NGOs, and private laboratories in low- and middle-income countries. Historically, GAH has been funded almost entirely by large foundations and bilateral donors. Donors now want GAH to become more financially sustainable and have set a target that, within 5 years, at least 60% of GAH’s annual operating budget should be covered by earned income (fees from tests and related services). GAH’s annual operating budget covers staff, training, logistics, and overheads and is USD 25 million, independent of volume within the ranges discussed in this case. Assume that manufacturing and shipping costs for the tests themselves are covered by a separate restricted grant for the next 5 years; GAH has recently introduced modest prices for some partners, but earned income currently covers only about 40% of annual operating costs. Leadership is considering moving to a much more aggressive, tiered pricing and growth strategy, but is concerned about potentially undermining its mission to reach the poorest and most vulnerable populations. GAH has hired your consulting team to advise whether and how it should pursue this more aggressive earned-income strategy while remaining true to its mission.

How is Creativity Assessed in Case Interviews?

Interviewers typically assess creativity through open-ended questions that lack exhibits or starting information. These questions challenge candidates to think on their feet and come up with multiple solutions independently. For example, you might be asked how to increase a company's market share without being given specific data points or frameworks. The expectation is to generate a variety of ideas, usually aiming for at least five distinct concepts. This not only showcases your creativity, but also your ability to think deeply and broadly about a problem.

💡 Pro Tip: Check out our Brain Teaser Collection to sharpen your creative thinking skills and prepare for unexpected questions.

Challenge Your Logical and Numerical Thinking

Keep calm!

Demonstrating Creativity in Case Interviews Effectively

While creativity is important, maintaining structure in your answers is equally crucial. Here are some strategies to effectively showcase your creativity during a case interview:

Organize by themes: Instead of listing random ideas as they come to mind, group your thoughts into high-level themes. This approach demonstrates structured thinking and helps you cover different aspects of the problem comprehensively. For instance, if asked to improve customer satisfaction, you might categorize your ideas into themes like product quality, customer service, and marketing strategies.

💡 Pro Tip: Use our Structuring Drills to practice breaking down complex problems into manageable themes. This will help you organize your ideas logically during interviews.

Drills

Structuring, logical, and numerical reasoning drills prepare you for the big day!

Check out drills

Sense-check ideas: Ensure that your ideas are practical and can be implemented in the given context. It’s important to show that your creative solutions are not just imaginative, but also feasible. Discuss the potential impact and challenges of each idea briefly to indicate your practical understanding.
Differentiate between quick wins and long-term solutions: Highlighting a mix of immediate actions and strategic, long-term initiatives shows that you can think short-term and long-term. Quick wins might include small adjustments that can be implemented quickly with minimal resources, while long-term ideas might involve significant investments or strategic changes.
Summarize and wrap up: After brainstorming, summarize your ideas along the key themes and indicate how they inform your overall answer to the case. This step not only reinforces your structured approach but also helps the interviewer follow your thought process and the rationale behind your recommendations.

Avoiding Creative Blocks in Case Interviews

Running out of ideas can be a challenge during a case interview. Here are some tips to keep the creative juices flowing:

Mind map on how to be creative in Case Interviews with four tips: using frameworks as starting points, being inspired by business news, practicing regularly with cases, and avoiding stress while collecting ideas.

Preparation: Familiarize yourself with common business problems and innovative solutions. Reading case studies and business news can provide a wealth of ideas and inspiration.
Practice: Regularly practice with case scenarios to build your creative muscle. The more you practice, the easier it becomes to generate ideas on the spot.

👉 Participate in Mock Interviews on PrepLounge to simulate real interview conditions and receive feedback on your creative thinking.

Use frameworks: While creativity goes beyond traditional frameworks, they can serve as useful starting points to ensure you cover all bases. Customize and expand upon these frameworks with your unique insights.
Stay calm and positive: Stress can stifle creativity. Stay calm, take a deep breath, and approach each question with a positive mindset.

Business Sense

Consulting Skills & Preparation

Business sense refers to the ability to quickly grasp economic dynamics and make decisions that are both strategically and commercially sound. In consulting, it’s not enough to repeat theories from your business degree. What matters is a deep understanding of how companies operate, what drives markets, and what different stakeholders are aiming to achieve. Consultants with strong business acumen can quickly adapt to new industries, understand client needs, and set priorities that make economic sense. They don’t just ask, “What is analytically correct?” – they also ask, “What truly benefits the company?” This mindset often makes the difference in a case interview.

Presentation and Communication

Consulting Skills & Preparation

The majority and the most obvious part of preparation is, of course, the substantive preparation for your case interview. However, you also need to present what you have learned in a way that gives your interviewer an impression of your personality and character. This means that you must appear confidentand communicate clearly and precisely. The best preparation is useless if you come across as closed-off and insecure. As a consultant, you must always appear trustworthy and confident when interacting with clients to be taken seriously and to enable you and your team to work in a solution-oriented manner. This is already tested in the case interview – albeit indirectly ;)

General Knowledge

Consulting Skills & Preparation

In case interviews, having solid general knowledge can make a big difference, especially in market sizing questions. Knowing basic facts about regions, population sizes, and economic indicators helps you build stronger arguments. It’s not just about the analysis itself but also about showing interviewers that you understand global trends and can quickly process key information — an important skill in consulting. In a case interview, quick and accurate estimates are essential. For example, if you're asked to evaluate the potential market for a product in a specific country, having solid data — like the population size — is crucial. Without this information, it can be challenging to make a meaningful calculation. In addition to national market data, it's important to know about key global markets. Being familiar with major economic regions like the U.S., China, and the EU is valuable because large consulting firms such as McKinsey and BCG operate extensively in these areas. A solid understanding of these regions shows that you can think about global factors and helps you stand out from other candidates. What Your Knowledge of Population, Economy & Geography Says About You Having strong general knowledge in specific areas not only shows that you are well-prepared, but also that you can quickly understand economic relationships—a crucial skill in consulting. When you have information like population sizes or a country's Gross Domestic Product (GDP) at your fingertips, you can quickly verify assumptions and make informed decisions, which is exactly what case interviews expect. Additionally, your knowledge of these topics demonstrates a genuine interest in world affairs and your ability to recognize and understand global trends. This insight is vital for evaluating how political, economic, and social changes affect businesses. It also highlights your capability to absorb and use complex data effectively. Population Country/Region Population (approx.) Worldwide 8.05 billion China 1.426 billion India 1.419 billion Europe (EU states) 450 million USA 335 million Indonesia 277 million Brazil 203 million Russia 143 million Japan 124 million Germany 83 million UK 68 million GDP Forecast in USD for 2024 Country/Region GDP 2024 (approx. in trillions USD) Worldwide 105 trillion USD USA 25 trillion USD China 18 trillion USD Japan 4.3 trillion USD Germany 4.5 trillion USD France 3.0 trillion USD UK 3.1 trillion USD India 3.9 trillion USD Italy 2.2 trillion USD Brazil 2.1 trillion USD Canada 2.2 trillion USD Key Data to Know for Your Case Interview In case interviews, making quick and accurate estimates is key. A good grasp of units, along with basic fraction and percentage calculations, is essential for working efficiently. Additionally, being comfortable with time units is important for making rough estimates and calculations. The table of larger and smaller time units below provides a handy overview of commonly needed values. These fundamental skills help you tackle tasks confidently and quickly.
