Preparing for Case Study Interview – Advice/Pointers?

Hey everyone,

I have a case study interview coming up next week for a business development/strategy role (healthcare/medtech) and was hoping to get some advice from folks who have gone through similar M&A-focused case interviews.

Format of the presentation:

  • 25–30 min: Case Study Presentation
  • 10–15 min: Q&A with executive leadership

Case Study Prompt:

“What public company should we acquire? Provide a detailed financial analysis, including a standalone and synergized discounted cash flow model. Justify your valuation of the company and prepare a presentation as if you’re presenting to executive leadership.”


My assumption is that the emphasis here will be less on sourcing or debating the perfect acquisition target and more on the financial analysis, modeling accuracy, and clarity of presentation/assumptions. In earlier conversations, it was mentioned that sourcing is handled by other teams, which makes me think the case is designed to test technical financial analysis (DCF, synergies, valuation) and my ability to communicate results to leadership rather than focusing heavily on broader strategy/operations.

With that in mind, I’d appreciate any advice on:

  • How deep to go into DCF modeling vs. using comps/precedents to support assumptions.
  • The best way to strike the balance between technical rigor and executive-level storytelling.
  • Common pitfalls or mistakes candidates make in these kinds of case studies.
  • Anything you wish you knew before walking into an M&A-focused presentation like this.

For an M&A-focused case study interview like this, here’s how you can prepare effectively:

1. Depth of DCF Modeling vs. Comps/Precedents

  • DCF Modeling: Since the prompt explicitly mentions a standalone and synergized DCF, this should be your primary focus. Ensure your model is detailed, with clear assumptions for revenue growth, margins, CAPEX, working capital, and synergies. Highlight key drivers and justify them with logical reasoning.
  • Comps/Precedents: Use these to validate your DCF assumptions. For example, leverage industry multiples (e.g., EV/EBITDA, P/E) to cross-check your valuation. This adds credibility and shows you understand market benchmarks.

2. Balancing Technical Rigor and Executive Storytelling

  • Technical Rigor: Your financial analysis should be accurate and defensible. Double-check your formulas, assumptions, and outputs. Include sensitivity analysis to show how changes in key variables (e.g., WACC, growth rates) impact valuation.
  • Executive Storytelling: Present your findings in a concise, structured manner. Use slides to:
    • Summarize the target company’s profile and strategic fit.
    • Highlight key valuation metrics (DCF outputs, multiples).
    • Explain synergies and their impact on valuation.
    • Conclude with a clear recommendation (e.g., “We recommend acquiring XYZ for $X billion due to [reasons].”).
  • Avoid overwhelming leadership with too much detail—focus on the “so what” of your analysis.

3. Common Pitfalls to Avoid

  • Overcomplicating the Model: Keep your DCF model clean and focused. Avoid unnecessary complexity that could lead to errors or confusion.
  • Weak Assumptions: Unsupported or unrealistic assumptions (e.g., overly optimistic synergy estimates) can undermine your credibility. Use industry data or precedents to back up your inputs.
  • Ignoring Risks: Failing to address potential risks (e.g., integration challenges, regulatory hurdles) can make your analysis seem incomplete.
  • Poor Communication: Even the best analysis can fall flat if it’s not communicated effectively. Practice delivering your presentation with confidence and clarity.

4. Additional Tips

  • Structure Your Presentation: Use a clear framework, such as:
    1. Executive Summary
    2. Target Company Overview
    3. Valuation Analysis (DCF, comps, synergies)
    4. Strategic Rationale
    5. Risks and Mitigation
    6. Recommendation
  • Practice Q&A: Anticipate tough questions from leadership, such as:
    • “Why did you choose this target?”
    • “How did you calculate synergies?”
    • “What are the key risks, and how would you mitigate them?”
  • Visuals Matter: Use charts, graphs, and tables to make your analysis visually appealing and easy to digest.

5. What You Wish You Knew

  • Time Management: In a 25–30 minute presentation, you’ll need to prioritize. Spend more time on valuation and synergies, less on background details.
  • Tailoring to the Audience: Executives care about the big picture—how the acquisition aligns with strategy and creates value. Don’t get lost in technical details without tying them back to the broader narrative.

By focusing on these areas, you’ll demonstrate both technical expertise and the ability to communicate effectively with leadership. Good luck—you’ve got this!
