Laos Tire

A manufacturer of tires in Laos has had a monopoly in the market for years due to high tariff on imports. If foreign producers wanted to import tires, they would have to pay a high import tariff which makes up 40% of the total cost to produce and ship to Laos. The Laotian government has now decided to lower the tariffs by 4% each year for the next ten years to open up the market to foreign companies and achieve lower consumer prices. Our client is concerned this move will affect their market position and hired us to investigate the effects and help them decide what to do.

Roland Berger Case: Onlinestar

Onlinestar, an online retailer of furniture and garden products (core business), has grown significantly in recent years as a result of an expansion of its product portfolio. The company mainly imports goods from Chinese manufacturers but also operates its own production of cat lavatories (special business) in Eastern Europe. The company sells its goods via Amazon and eBay, and recently via an online shop on its website. Despite this development, the financial ratios have deteriorated in recent years. In particular, the gross profit margin decreased significantly. Combined with a significant increase in shipping costs, this led to a negative result for the first time in the recently ended fiscal year and a resulting strained financial situation. Against the background of expected stagnating sales for the current financial year, short-term action is required.The board of Onlinestar asks you for an analysis of the reasons for the negative result as well as a derived recommendation for action. As a consultant, you should bring in your knowledge in online trading and develop solutions. In addition, the management board would like to receive a sales and gross profit plan from you for the current financial year.

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 confident and 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 YouHaving 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.PopulationCountry/RegionPopulation (approx.)Worldwide8.05 billionChina1.426 billionIndia1.419 billionEurope (EU states)450 millionUSA335 millionIndonesia277 millionBrazil203 millionRussia143 millionJapan124 millionGermany83 millionUK68 millionGDP Forecast in USD for 2024Country/RegionGDP 2024 (approx. in trillions USD)Worldwide105 trillion USDUSA25 trillion USDChina18 trillion USDJapan4.3 trillion USDGermany4.5 trillion USDFrance3.0 trillion USDUK3.1 trillion USDIndia3.9 trillion USDItaly2.2 trillion USDBrazil2.1 trillion USDCanada2.2 trillion USD Key Data to Know for Your Case InterviewIn case interviews, making quick and accurate estimates is key.
