What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

  • Size the annual takeaway-coffee market of the city of Lakeport top-down, segment by segment, and state it the way an interviewer wants to hear it.
  • Size the same Lakeport coffee market bottom-up from the outlets that sell it, compare it with your top-down figure and decide whether the estimate holds.
  • Harborline Fitness, a gym chain, earned less this year. You split profit into revenue (price × volume by segment) and costs (fixed + variable) and find the driver.
  • Northvale Foods wants to launch a protein snack bar. You work out the break-even volume, the market share it needs, the annual profit and the payback period.
  • Pixelpost, a photo-book app, tests annual subscription prices. From the survey you find the revenue-maximising and the profit-maximising price with INDEX/MATCH on MAX.
  • Kestrel Logistics wants to buy Fernway Freight. You estimate cost and revenue synergies, value them and check whether they cover the takeover premium.
  • Check four classic mental-math shortcuts against the exact Excel answer: the rule of 72, an exact doubling time, a percentage of a percentage and two changes in a row.
  • The interviewer hands you an exhibit: Alder Outdoor's revenue by channel. You read it like a consultant and back the headline with one calculation.

About this course

Consulting interviews test whether you can structure a problem and do the numbers quickly and correctly. Each lab here is a mini case. You size a market top-down from population, penetration, frequency and price, then rebuild it bottom-up and sanity-check the result. A profitability tree pinpoints what caused a decline. You calculate break-even and payback for a launch, set a price from a willingness-to-pay survey and test whether synergies justify an acquisition premium. Mental maths drills cover the rule of 72, percentages of percentages and growth, and the final case asks you to read an exhibit and draw the right conclusion. For students and professionals applying to strategy and consulting roles.
