There are 14 common case interview types. These different types of consulting cases include: market sizing, profitability, growth strategy, pricing, market entry, M&A, operations, private equity, valuation, marketing, new product, HR, economic, and brain teasers.
Market sizing case interviews test a candidate's ability to estimate the size of a specific market using logical thinking and quick calculations. These cases often involve estimating quantities or market value, such as the number of smartphones sold in a country annually or the total revenue of a new product segment.
Candidates must break down complex problems into manageable parts, make reasonable assumptions, and use basic arithmetic to reach an estimation.
Examples of market sizing cases:
Profitability case interviews focus on identifying the reasons behind a company's declining profits and proposing viable solutions. These cases require an in-depth analysis of revenues, costs, and market conditions to determine the root cause of profitability issues.
Examples of profitability cases:
Growth strategy case interviews involve developing strategies for a company to achieve growth, whether through market expansion, product diversification, or other strategic initiatives. Candidates need to demonstrate their ability to identify growth opportunities, assess market potential, and create actionable plans.
Examples of growth strategy cases:
Pricing case interviews test a candidate's ability to determine the optimal price for a product or service. These cases require an understanding of market demand, competitive landscape, and cost structure. Candidates need to balance profitability with market competitiveness and customer willingness to pay.
Examples of pricing cases:
Market entry case interviews focus on developing a strategy for a company to enter a new market. These cases assess a candidate's ability to evaluate market potential, understand the competitive environment, and identify entry barriers.
Examples of market entry cases:
Merger and acquisition case interviews involve analyzing the strategic fit, financial benefits, and potential risks of merging with or acquiring another company. Candidates need to assess synergies, integration challenges, and the overall impact on the company's market position.
Examples of M&A cases:
Operations case interviews focus on improving the efficiency and effectiveness of a company's operations. These cases require analyzing processes, identifying bottlenecks, and proposing solutions to optimize performance.
Examples of operations cases:
Private equity case interviews involve evaluating investment opportunities in private companies. Candidates need to assess the financial health, growth potential, and strategic fit of target companies.
Examples of private equity cases:
Valuation case interviews require candidates to determine the value of a company or asset. These cases involve financial modeling, analyzing cash flows, and applying valuation methods such as discounted cash flow (DCF) or comparable company analysis.
Examples of valuation cases:
Marketing case interviews focus on developing strategies to promote and sell products or services. These cases require an understanding of market research, customer segmentation, and marketing mix elements.
Examples of marketing cases:
New product case interviews involve developing strategies for launching and managing new products. These cases assess a candidate's ability to identify market opportunities, define product features, and create go-to-market plans.
Examples of new product cases:
Human resources case interviews focus on addressing issues related to workforce management, such as recruitment, retention, and organizational development. These cases require candidates to propose solutions for improving HR practices and increasing employee satisfaction.
Examples of HR cases:
Economic case interviews involve analyzing economic trends and their impact on business decisions. Candidates need to apply economic principles to evaluate market conditions, regulatory changes, and macroeconomic factors.
Examples of economic cases:
Consulting brain teasers are short puzzles or riddles designed to assess a candidate's logical thinking, creativity, and problem-solving skills. These cases often require thinking outside the box and applying unconventional approaches.
Examples of consulting brain teasers:
There are three major formats of case interviews: traditional case interviews, unstructured case interviews, written case interviews, and group case interviews.
The traditional case interview is the most common format and typically involves a one-on-one session between the candidate and the interviewer. In this format, the interviewer presents a business problem or scenario, and the candidate is expected to analyze the situation, develop a structured approach, and propose a solution.
The interviewer may provide additional information or ask follow-up questions as the candidate works through the case. This format assesses a candidate's problem solving skills, analytical thinking, communication abilities, and ability to perform under pressure.
Tips for traditional case interviews:
Unstructured case interviews are a variant where the format and direction of the interview are intentionally less defined compared to structured counterparts. Rather than presenting a clear problem statement, unstructured case interviews often involve more open-ended questions and hypothetical scenarios.
This format is designed to assess a candidate's ability to think creatively, adapt quickly, and demonstrate analytical skills in ambiguous situations.
Tips for unstructured case interviews:
In a written case interview, candidates are given a packet of information, including data, charts, and other relevant documents, and are asked to analyze the information and develop a recommendation in a written format.
This type of interview usually allows for more time compared to a traditional case interview, often ranging from 60 to 90 minutes. Candidates need to synthesize the information, identify key insights, and structure their findings into a coherent and persuasive presentation.
The written case interview evaluates a candidate's ability to process and interpret complex data, as well as their written communication skills.
Tips for written case interviews:
The group case interview format involves multiple candidates working together to solve a case presented by one or more interviewers. This format assesses not only individual problem solving abilities but also teamwork, leadership, and communication skills.
Candidates must collaborate to analyze the case, share their insights, and collectively develop a solution. The group dynamics and how each candidate contributes to the discussion are closely observed by the interviewers.
This format is particularly useful for evaluating how candidates perform in a team setting, manage conflict, and lead discussions.
Tips for group case interviews:
Traditional case interviews can either be interviewer-led or candidate-led.
Interviewer-led case interviews are structured and directed by the interviewer, who guides the candidate through the problem-solving process by asking specific questions and providing information in a step-by-step manner. This style is commonly used by firms like McKinsey.
In an interviewer-led case, the candidate needs to respond to each prompt, analyze the information provided, and move to the next question based on the interviewer's direction. This format allows the interviewer to assess a candidate's ability to follow a logical progression, think quickly, and articulate their thoughts clearly.
Tips for interviewer-led cases:
Candidate-led cases, preferred by firms like BCG and Bain, are more open-ended and require the candidate to take the initiative in driving the case forward. In this style, the candidate is expected to define the problem, develop a structured framework, and guide the conversation by asking relevant questions and exploring different areas of the case.
The interviewer provides information and feedback based on the candidate's questions and direction. This format tests a candidate's ability to structure problems independently, prioritize issues, and think strategically.
