Business Sense

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.
 

 

Why Your Business Sense Matters in Consulting

As a consultant, you’re expected not only to analyze complex problems but also to think in a solution-oriented and entrepreneurial way. A strong business mindset helps you put analyses into context, assess actions realistically, and focus on generating maximum client value.

In day-to-day consulting, you're working under pressure, collaborating with decision-makers, and constantly weighing trade-offs. Those who think commercially and can strategically prioritize have a clear edge.

In a case interview, showing that you understand markets and business models is key – it sets you apart and proves your readiness for the job.

👉 In our Case Library, you can prepare effectively with curated practice cases and put your business sense to the test.

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.

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

Revolut Mock Interview: Strategy & Operations
You are part of the Strategy & Operations team at Revolut. Revolut has had significant growth over the past couple of years, with customer base growing 20-30% per year. Our apps have also been highly rated in the various app stores - be it GooglePlay or on the Apple store. Revolut's current customer strategy is to segment customers based on their subscription tiers/plans. - Standard: Free - Plus: $3.99/mth - Premium: $7.99/mth - Metal: $14.99/mth - Ultra: Ultra $55/mth Key differentiation between the plans are in the pricing and features. Namely, the more expensive tiers like Metal and Ultra have additional features such as personalized and premium card design, free access to lifestyle apps (e.g. Financial Times, Class Pass etc), better FX rates and priority customer support. It's great that Revolut has been expanding rapidly, but we are starting to see some stresses on our existing operations and processes. One key area of concern is in customer service, our satisfaction scores have started to trend down and call center headcounts and costs have been increasing in recent years, but we are struggling to handle the load of incoming requests and tickets. You have been tasked to lead a project to solve this problem without ballooning costs.

AltaVia Elevators
Your client is AltaVia Elevators, a Vienna-based elevator manufacturer and the number 4 player in Europe. The company has two businesses: New equipment: AltaVia sells about 20,000 new elevator units per year to construction projects, generating about EUR 1.6 billion in revenue. Service: AltaVia maintains about 400,000 units under paid service contracts, generating about EUR 960 million in revenue. Every installed elevator legally requires certified maintenance, and new units include two years of free maintenance by AltaVia. When that period ends, the building owner decides whether to sign a paid AltaVia service contract or switch to a third party. Paid service customers can also leave AltaVia later. New equipment sales have just reached a record high and the order book is full. Yet group operating profit has declined for the third year in a row. Over the same period, LiftServ, a PE-backed independent service group, has been buying small maintenance firms across Europe and prices standard maintenance about 30% below AltaVia. The CEO wants to know: why is profit falling despite record sales, and what should AltaVia do about it?

Roman Roads – Launching Autonomous Taxis in Italy
UrbanAI Mobility is a European venture-backed startup specialising in autonomous vehicle (AV) software and fleet management. The company is now evaluating its first consumer-facing market entry. Italy has been shortlisted due to its high urban density, significant tourist traffic, and a regulatory framework that recently authorised Level 4 AV trials in designated city zones. Rome has been identified as the priority launch city, given its combination of high ride-hailing demand, international tourism, and a mayoral administration publicly supportive of smart-city initiatives. The competitive landscape includes established ride-hailing operators (FREE NOW, Uber), traditional licensed taxis (approximately 14,000 in Rome), and two European AV startups that have announced intentions to launch in Southern Europe within 18 months. “UrbanAI is considering launching an autonomous taxi pilot in Rome. Should they do it and if so, how should they approach the market entry?”

How Business Sense Shows Up in Case Interviews

Your business sense won’t be tested directly – but it shows up in your thinking, your assumptions, and your recommendations. Here are five moments when it really counts:

5 tips on how to show business sense in case interviews

1. Define a clear objective.

Clarify what the company wants to achieve in the case. Is it short-term profit, long-term growth, or a stronger market position? A well-defined goal aligns your analysis and recommendations – and shows you understand the business context.

2. Develop sound hypotheses.

Top candidates derive economically plausible hypotheses. If revenue is dropping, explore potential causes like demand, pricing, or competitive pressure.

3. Evaluate actions realistically.

Go beyond theory. Consider real-world feasibility, conflicting objectives, and strategic risks. Instead of simply saying “raise prices,” consider price elasticity, customer segments, and likely competitor reactions.

4. Interpret numbers in the right context.

Numbers only make sense when interpreted correctly. High margins might signal a premium position – or upcoming competitive threats. Business sense means understanding what the numbers imply in context.

5. Make a well-founded recommendation.

Your final recommendation should be logical and economically viable. Acknowledge risks or gaps, and show that your solution could succeed in the real world.
 

How to Train Your Business Sense

Business sense isn’t innate – it’s a skill you can develop. The key is to build a solid understanding of economic principles and learn how real-world decisions are made.

Start by regularly reading business news. Outlets like New York Times, the Wall Street Journal or the Financial Times will help you get a feel for markets, business models, and strategic thinking. Go beyond the facts – try to understand the economic rationale behind each story.

When practicing case interviews, stay sharp and reflective. Ask yourself: Is my reasoning not only logical but also economically sound?

Mock interviews with peers are especially helpful. You’ll improve your communication skills and receive valuable feedback.

👉 Use our Meeting Board to find peers and practice together.

Also, think like an entrepreneur in daily life. Observe companies, analyze new strategies, and reflect on what drives success or failure. The more often you go through this process, the sharper your business intuition becomes – and that’s what sets you apart in interviews.
 

Key Takeaways

Business sense is one of the most important success factors in both consulting and case interviews. It reflects your ability to quickly recognize economic patterns, form sound assumptions, and make realistic, client-oriented decisions. In interviews, what sets top candidates apart isn’t memorized theory but the ability to see the bigger picture: understanding what really matters to a business, prioritizing strategically, and proposing solutions that are both practical and value-driven.

To demonstrate your business sense, it’s crucial to clearly define the objective of the case, develop plausible hypotheses, assess potential actions not only analytically but also from a business standpoint, and interpret numbers within the correct context. Your final recommendation should be not just logical, but economically viable and well thought through.

The good news is that business sense can be learned. By regularly reading business news, reflecting on strategic decisions, working through case interviews critically, and actively seeking feedback, you’ll build a strong foundation in economic thinking. Over time, this mindset will not only boost your interview performance but also set you up for long-term success in consulting.

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.
