Score me, then build my plan.
Score on the rubric BCG, Bain & McKinsey use, plus a plan paced to your interview. Voice-default. No signup until your debrief.
A real 30-minute case. You read the brief, you talk, the interviewer responds. When the case calls for evidence — a chart, a table — it's handed to you in the moment.
MealMosaic manages hospital foodservice and faces high tray waste, patient complaints, and nursing disruptions. Leadership needs to decide whether to move to on-demand ordering, simplify menus, improve dietitian forecasting, or cut portion sizes.
Client objective: Reduce food waste by 25% while raising meal satisfaction by 8 points.
Constraints: Clinical diets must be safe; kitchen staffing fixed; nurses cannot absorb more ordering work.
A 10-minute baseline gives you this. After that, every 30-minute case you sit gets the same depth of read.
On track for McKinsey, top third of first-time candidates. One blocker — math.
Communication and structure carry the case. Math is the active blocker. The deeper pattern is hypothesis stickiness — you committed early (good) but didn't revisit when the data turned (at 06:10).
One anonymized example. Yours will read differently — built only from your session.
Friends can't score you. Coaches give you one opinion per week, and you're the only one timing the math.
