How to prepare for your case interview
Next to personal fit interviews, case interviews are a core element of the consulting recruitment process. Case studies are a valuable tool for both sides because they showcase the skills that we use in day-to-day client situations – structuring problems, making sound assumptions under uncertainty, and performing under pressure.
During the case study, we would like to see how you:
- Structure complex problems logically
- Analyze data and draw meaningful insights
- Exercise business judgment
- Communicate clearly and concisely
- Stay adaptable and collaborate with your counterpart
- Enjoy cracking a problem
How to Prepare Effectively
- Understand the format: Practice and know the structure of typical case types
- Practice structured thinking: Learn how to break down problems into clear, MECE components and form hypotheses
- Gain practice: Complete live practice cases with partners to mimic real interview dynamics
- Improve mental math & data skills: Train fast, accurate calculations and chart interpretation
- Strengthen communication: Practice thinking aloud, structuring your answers on the go and delivering crisp recommendations
- Embrace ambiguity: Stay flexible, adapt as new information comes in and avoid memorized, rigid frameworks
- Simulate real conditions: Time yourself, do not use help such as calculators and practice with a partner
We also prepare for your case interview: We study your CV and understand who you are—to ensure a focused conversation when we meet.
