Anatomy of a case: the five beats

Intuition

Almost every case, regardless of topic, follows the same five beats. Once you can feel the rhythm, an unfamiliar prompt stops being scary, you always know what move comes next. It is like the structure of a song: the lyrics change, but verse-chorus-verse stays put.

Framework

The five beats:

1. Prompt, the interviewer states the situation and the question.
2. Clarify + structure, you ask 1-2 sharp questions, then lay out how you'll break the problem down.
3. Analysis, you work through your branches, doing math and reading any data the interviewer provides.
4. Synthesis, you step back: what is the analysis actually telling you?
5. Recommendation, you give a clear answer, the reasons behind it, and the risks.

Worked Example

Prompt: "Our grocery client's profits fell 20%. Why, and what should they do?" → Clarify: "Is this a margin problem or a volume problem?" → Structure: "I'll split profit into revenue and costs, then dig into whichever is driving the drop." → Analysis: walk the profit tree. → Synthesis: "Costs are flat; the drop is a volume decline in one region." → Recommendation: "Focus on that region's footfall; here's what I'd test first and the risk if I'm wrong."

Run the rhythm on a hotel chain: "Occupancy is fine but profit is down." Clarify: "Across all brands or one?" Structure: revenue per room versus cost per room. Analysis: average daily rate fell 9% after a discounting push. Synthesis: "Occupancy was bought, not earned, this is a self-inflicted price problem." Recommendation: tighten discount approval rules; the risk is losing the occupancy those discounts were buying. Different industry, identical verse-chorus-verse.

In the room

The beats only score if you drive the transitions, the interviewer should never have to drag you to the next one. Entering beat two: "Before I structure, two quick clarifications: is the 20% drop company-wide, and over what period?" Leaving analysis for synthesis, plant a flag: "Stepping back, here's what the numbers are telling us." That one sentence separates you from candidates who dump figures and wait. And when the interviewer says "we have a couple of minutes left, " that is the recommendation cue, take it: "Happy to give my recommendation now." Then deliver it answer-first. At each handoff the interviewer is scoring exactly one thing: do you know where you are in the case, or are they navigating for you?

Pitfalls

• Skipping the clarify/structure beat and diving straight into analysis.
• Never doing the synthesis beat, dumping numbers without saying what they mean.
• A recommendation with no risks named (interviewers always probe for them).
