Deloitte Case: Footloose

Duraflex is a German footwear company with annual men’s footwear sales of approximately €1 b. They have always relied on the boot market for the majority of their volume. In this market they compete with three other major competitors. In the fall of 2019, Badger – one of Duraflex’s competitiors – launched a new line of aggressively priced work boots. The strong success of this line has caused Duraflex’s management to re-evaluate their position in work boots. With limited additional resources, the management must now decide if they should focus their efforts on competing with Badger in the work boot sector, or allocate their resources on further strengthening their position with casual boots.

Inverto Case: FashionForward’s Sourcing Shake-up

FashionForward is a mid-sized, private-label fashion retailer headquartered in Europe with €600 million in annual revenue. Its product portfolio includes fast-fashion collections for men and women, sold in 220 stores across six countries, and online. The company currently sources approximately 85% of its total production volume from Bangladesh, heavily relying on just three key suppliers for over 70% of that volume. Their procurement strategy is highly cost-driven, and supplier relationships are transactional. FashionForward has now asked Inverto to develop a new sourcing strategy. Over the last 18 months, FashionForward has faced increasing procurement challenges: - A drop in demand for trend-sensitive fashion categories - Long lead times (up to 40 days), limiting reactivity to seasonal trends - Repeated shipping delays and FX volatility from Banglades - Overstocking in basics and stockouts of fashion-forward items - ESG non-compliance flagged in two factories during an audit - Growing pressure from the board to increase agility and reduce dependency on Bangladesh

PE Aurora Capital - Possible aquisition of Nordstock Exchange Group

Aurora Capital Partners is a European investment fund. Aurora is considering acquiring NordStock Exchange Group (NEG), a publicly listed company that owns and operates a Nordic stock exchange and related services. NEG earns revenue from four main activities: 1. Equity listing fees (companies paying to list their shares) 2. Cash equities trading (fees on buying and selling shares) 3. Derivatives trading (options, futures, etc.) 4. Market data & analytics (selling data feeds and analytics to banks and investors) NEG was historically seen as a solid, predictable business. However, over the last five years it has grown more slowly and is less profitable than some competing European exchanges. Its share price has also underperformed. Aurora believes that, under new ownership, NEG could: - Improve its technology and reduce outages - Launch new derivatives products - Grow its higher-margin data & analytics business - Streamline operations and increase profitability Aurora has asked you to: 1. Assess whether NEG looks like an attractive acquisition 2. Identify key performance gaps vs. peers 3. Estimate, in simple terms, how much profit could increase under an improvement plan 4. Suggest actions and a recommendation

In diesem Zusammenhang hat das Unternehmen auch eine weitere Zielgruppe definiert und eine entsprechende Kundenliste erstellt. Darüber hinaus wurden im laufenden Geschäftsjahr durch den Zukauf von Daten über ein soziales Netzwerk zusätzlich neue Kunden hinzugewonnen. Die CarVermietungen GmbH hat im letzten Quartal außerdem in P2P-Carsharing investiert, da sich dieses neue Geschäftsmodell im Ausland bereits als vielversprechend erwiesen hat.

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:

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.
