If you aspire to join the ranks of elite consulting firms like McKinsey, BCG, or Bain, your journey starts with mastering the case interview—a cornerstone of the consulting recruitment process. These interviews are designed to test your problem-solving skills, creativity, and ability to think on your feet. While intimidating at first glance, case interviews can become manageable—and even enjoyable—with the right preparation. Enter Marc P. Cosentino's Case in Point: Complete Case Interview Preparation, the definitive guide that has helped countless candidates secure their dream consulting jobs.

What Makes Case in Point Stand Out?

Marc P. Cosentino demystifies the case interview process by offering a structured, practical approach that combines theory with actionable strategies. Whether you're new to case interviews or looking to refine your skills, Case in Point equips you with frameworks, real-world examples, and insider tips to succeed.

Let’s delve into some of the book's most valuable lessons and how you can apply them.

1. Frameworks for Problem-Solving: The Ivy Case System

A common mistake in case interviews is diving into details without a clear strategy. Cosentino’s Ivy Case System provides a roadmap for tackling cases systematically.

Example: Profitability Case

Imagine you’re asked, “Why has our client’s profitability declined?” Instead of throwing out random ideas, you can apply the profitability framework:

  • Revenue: Analyze changes in pricing, volume, or product mix. For instance, has a competitor launched a similar product at a lower price?
  • Costs: Examine fixed and variable costs. Are raw material prices rising? Is the supply chain inefficient?

This structured approach not only keeps you focused but also demonstrates to the interviewer that you think like a consultant.

💡
Always start by summarizing the problem and confirming your understanding. For example: "So, the goal is to identify the reasons for the profitability decline and propose actionable solutions. Let’s break this down by looking at revenues and costs."

2. Market-Sizing Questions: Thinking on Your Feet

Market-sizing questions are a staple of case interviews. These questions test your ability to make logical assumptions and calculate estimates.

Example: Market Size for Coffee Shops

“How many cups of coffee are sold in Riyadh each day?”

  1. Estimate the population of Riyadh: ~7 million.
  2. Assume 50% drink coffee daily: 3.5 million.
  3. Assume each person drinks 1 cup per day: 3.5 million cups daily.

This logical breakdown showcases your ability to think systematically under pressure.

💡
When making assumptions, state them clearly. This allows the interviewer to follow your reasoning and correct any unrealistic estimates.

3. The Power of Communication: Tell a Story

In consulting, how you present your findings is as important as the findings themselves. Cosentino emphasizes the importance of storytelling in case interviews.

Example: Structuring Your Response

When asked to recommend a market-entry strategy, organize your response like this:

  1. Headline: “Based on the analysis, I recommend entering the market through a joint venture.”
  2. Supporting Points: Highlight the market size, competitive landscape, and cost advantages.
  3. Conclusion: Summarize the benefits and potential risks.
💡
Use simple visuals like a decision tree or cost breakdown during interviews (if allowed). These visuals make your analysis more engaging and easier to follow.

4. Behavioral Interviews: The STAR Method

Consulting interviews aren’t just about solving cases—they also assess your soft skills through behavioral questions. Cosentino’s STAR method helps craft compelling answers:

  • Situation: Briefly describe the context.
  • Task: Explain your role.
  • Action: Detail the steps you took.
  • Result: Share the outcome and impact.

Example: Leadership Question

“Tell me about a time you led a team under pressure.”

  1. Situation: “During university, I led a team for a case competition.”
  2. Task: “Our challenge was to develop a sustainability strategy within 48 hours.”
  3. Action: “I delegated tasks based on strengths, facilitated brainstorming sessions, and ensured clear communication.”
  4. Result: “We won first place, and our strategy was praised for its feasibility.”
💡
Quantify your results whenever possible. For example, “Our efforts led to a 15% increase in efficiency.”

5. Practice Makes Perfect: Real-World Cases

Cosentino provides numerous practice cases, each with detailed solutions. These aren’t hypothetical scenarios—they mirror real challenges faced by consultants.

Example: Growth Strategy for a Tech Startup

“How can a startup increase its user base by 20%?”

  • Explore Market Segments: Target niche audiences, like students or remote workers.
  • Leverage Partnerships: Collaborate with established brands for co-marketing campaigns.
  • Optimize Pricing: Introduce freemium models to attract new users.

By practicing similar cases, you’ll become comfortable tackling diverse problems.

💡
During practice, time yourself to simulate real interview conditions. Aim to complete each case in 20–30 minutes.

6. Navigating the Unexpected: Flexibility is Key

Interviews often throw curveballs to test your adaptability. Cosentino advises staying calm and reframing challenges as opportunities to showcase creativity.

Example: A Curveball Question

“What would you do if your client’s main competitor launched a disruptive product?”

  • Acknowledge the disruption: “This poses a significant challenge to our client’s market share.”
  • Suggest immediate actions: “We could conduct market research to understand consumer preferences and explore rapid innovation opportunities.”
  • Think long-term: “A loyalty program might help retain customers.”
💡
If you’re unsure, ask clarifying questions. This buys you time and shows that you approach problems methodically.
