Understanding the Case Interview for Non-Business Majors


Case interviews may seem complicated and daunting, especially if you’re a non-business major.


However, don’t worry because we’ll explain in simple terms: what is a case interview, why companies use case interviews, and how much business knowledge you actually need for them.


What is a case interview?


A case interview is a type of job interview used primarily in management consulting and sometimes in other industries to assess a candidate's problem-solving and analytical skills.


During a case interview, the candidate is presented with a hypothetical business scenario or problem that the interviewer has designed.


The candidate is then expected to analyze the situation, ask relevant questions, and provide a structured and logical solution or recommendation.


The structure of a case interview can vary, but it usually involves the following steps:


  • Problem Statement: The interviewer presents the candidate with a business problem or scenario. This could involve market entry strategies, cost optimization, product launch decisions, etc.


  • Clarification: The candidate should ask clarifying questions to better understand the problem and its context. This also helps in identifying relevant information and potential areas to explore.


  • Framework: Candidates often use frameworks, structured approaches, to break down complex problems into manageable components.


  • Hypothesis: Based on the initial information, the candidate might form a hypothesis or initial approach to tackling the problem.


  • Quantitative Analysis: The candidate may be provided with additional data or information related to the scenario. Analyzing this data is crucial for making informed decisions.


  • Qualitative Discussion: The interviewer may engage in a discussion to assess business acumen and intuition related to the problem statement


  • Conclusion: The candidate presents their solution or recommendation, outlining the reasoning behind it and addressing any potential concerns.


Case interviews are challenging because they require both analytical skills and the ability to communicate those skills effectively.


Candidates are often judged not only on their final solution but also on how they arrived at it, their thought process, and their ability to adapt to new information or unexpected twists in the scenario.


Why do companies use case interviews?


Companies use case interviews for several reasons:


1. Assess Problem-Solving Skills: Case interviews are an effective way to evaluate a candidate's ability to analyze complex problems, think critically, and develop logical solutions.


2. Assess Structured Thinking: Companies look for candidates who can break down complex problems into manageable parts using structured frameworks.


3. Assess Client-Facing Skills: In consulting and client-facing roles, employees need to convey ideas and recommendations clearly to clients. Case interviews assess a candidate's communication skills, including their ability to explain complex concepts in a concise and understandable manner.


4. Predict On-The-Job Success: Case interviews simulate real-world scenarios that candidates might encounter in their roles. This helps companies gauge how well candidates can apply their skills to practical situations they might face on the job.


5. Assess Cultural Fit: Case interviews often involve interactions with interviewers. This provides the company with insights into how well a candidate might fit into the company's culture and how they handle interpersonal interactions.


How much business knowledge do case interviews require?


The amount of business knowledge you need for case interviews can vary depending on the level of the role you're applying for and the industry or sector you're interested in.


However, it's important to note that while some level of business knowledge is beneficial, case interviews are primarily designed to test your problem-solving, analytical, and communication skills rather than your depth of business expertise.


Here's a general guideline on the level of business knowledge you might need:


Foundational Business Concepts: You should have a basic understanding of fundamental business concepts such as profit and loss, revenue, costs, market dynamics, supply and demand, competition, and business operations.


Supply Chain Concepts: You should have a basic understanding of all of the elements in a supply chain, including suppliers, manufacturers, distributors, and retailers.


Industry Awareness: Familiarize yourself with the industry or sector relevant to the role you're applying for. Understand key trends, challenges, and dynamics that could impact business decisions.


Business Models: Have a grasp of common business models, like B2B (business-to-business), B2C (business-to-consumer), subscription models, e-commerce, etc.


Financial Literacy: While you don't need to be a financial expert, having a basic understanding of financial statements (income statement, balance sheet, cash flow statement) and financial ratios can be helpful.


Strategy Concepts: Be aware of strategic concepts such as differentiation, cost leadership, value chain analysis, and competitive advantage.


Reading and Interpreting Data: You should be able to read and interpret basic data, charts, and graphs related to business performance.


This may sound like a lot, but don’t worry because we’ll give you an overview on many of these topics later on in the article.


It's important to note that interviewers don't expect you to have deep industry-specific knowledge, especially for entry-level positions.


Instead, they want to see how well you can think critically, analyze information, and communicate your thought process.


As you prepare for case interviews, focus on developing strong problem-solving skills, practicing with mock cases, and honing your ability to communicate your ideas clearly.


While having some business knowledge is helpful, the emphasis is on your ability to apply your skills to unfamiliar scenarios and demonstrate your capacity to come up with well-structured solutions.


Leveraging Your Non-Business Background in Case Interviews


Having a non-business background can actually be an asset during case interviews, as it brings a unique perspective and a diverse set of skills to the table.

 Here’s a list of transferable skills you probably already have that you can transfer from your major or background to case interview success:


1. Analytical Thinking: Many non-business majors require strong analytical skills. Whether you've conducted scientific research, solved engineering problems, or analyzed data in your field, emphasize your ability to dissect complex issues and draw meaningful insights.


2. Problem Decomposition: Non-business majors often deal with intricate problems that need to be broken down into manageable parts. Discuss how you've tackled multifaceted challenges by dividing them into smaller components, a skill highly valued in consulting.


3. Data Interpretation: If your academic background involves data analysis, showcase your proficiency in interpreting data sets, drawing conclusions, and making data-driven decisions. This can be particularly helpful when dealing with quantitative cases.


4. Research Acumen: Non-business fields frequently involve research projects. Highlight your ability to gather relevant information, synthesize findings, and apply research methodologies to solve problems.


5. Complex Systems Understanding: If your studies involved understanding complex systems (e.g., biological systems, environmental processes), relate this to your capacity to comprehend intricate business ecosystems and propose effective strategies.


6. Attention to Detail: Fields like science and technology often require meticulous attention to detail. Explain how this skill enables you to identify nuances and uncover critical insights in case scenarios.


7. Project Management: If you've managed projects or handled tight deadlines during your studies, draw parallels to the time-sensitive nature of consulting engagements and your ability to manage multiple tasks effectively.


8. Adaptability: Many non-business majors need to adapt to changing circumstances, evolving research, or new discoveries. Showcase your adaptability and how you thrive in dynamic environments, which mirrors the fast-paced nature of consulting.


9. Interdisciplinary Approach: Your non-business background likely involves interdisciplinary thinking. Highlight how your diverse knowledge enables you to approach problems from different angles, facilitating creative solutions.


10. Communication Skills: Non-business majors often need to explain complex concepts to audiences with varying levels of expertise. Showcase your ability to communicate effectively, a key competency in consulting.


11. Ethical and Moral Reasoning: Some non-business fields require ethical considerations. Discuss your experience navigating ethical dilemmas and how this can contribute to responsible decision-making in consulting.


12. Innovation: Non-business majors often drive innovation in their fields. Describe how your innovative thinking can bring fresh perspectives to consulting challenges.


13. Cultural Awareness: Non-business fields often intersect with diverse cultures and backgrounds. Explain how this has honed your cultural sensitivity, which is valuable when working with clients from various industries and regions.


Incorporating these transferable skills into your case interview responses demonstrates your suitability for consulting roles, regardless of your academic background.


Connect your experiences to the core competencies sought in consulting, and showcase how your non-business expertise uniquely positions you as a strong candidate who can contribute fresh insights and well-rounded problem-solving skills.
