How to Practice Case Interviews Effectively
Read the Prompt Carefully
Take 30 seconds to absorb the problem. Identify the key question, client context, and any constraints before jumping into structure.
Build Your Framework
Create a MECE structure tailored to this specific case. Avoid generic frameworks — show the interviewer you can think from first principles.
Analyze with Numbers
Drive toward a quantitative answer. Practice mental math, set up calculations clearly, and explain your assumptions out loud.
Synthesize a Recommendation
End with a clear, actionable recommendation. State your conclusion first, then support it with 2-3 key reasons from your analysis.
