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.

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 demandpricing, 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 threatsBusiness 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 marketsbusiness 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.

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.
