1. 036How would you forecast revenue for a company you have never modelled before?ModellingIntermediatetechnicalHoulihan LokeyInvestment Banking · New York · 2026

   Say this

   Build it from drivers, never from a growth rate. Find the two physical quantities that multiply to revenue, price and volume in some form, then forecast each separately against something observable.

   Then walk it

   1. Decompose first. A retailer is stores times sales per store. An airline is available seat miles times load factor times yield. A software business is customers times average revenue per customer. A bank is loan balances times net interest margin.
   2. Forecast each driver against something external: industry capacity, population, disposable income, an installed base, a contract backlog. That makes the forecast falsifiable and lets you update it when the external data moves.
   3. Cross-check top-down. If your bottom-up build implies the company takes six points of market share in two years, you need a reason. Reconciling bottom-up to market size is the sanity check that catches most bad models.
   4. Separate organic from acquired growth. A company growing 15 percent of which 10 is bought is a completely different business from one growing 15 organically, and blending them hides that.
   5. Then sanity-check against history: is the implied growth faster than the company has ever achieved? If so, say why this time is different, or lower it.
   6. A flat growth-rate assumption is acceptable only in the terminal years, and even then you should say what it implies.

   Where candidates lose it

   Applying a growth percentage to last year's revenue. It cannot be argued with, cannot be updated by new data, and gives you no basis for a variant view. Driver-based building is the entire point.

   • What is the driver for the company we cover?
   • How do you reconcile bottom-up to market size?
   • Where does your forecast differ from consensus?

2. 090How did you arrive at the assumptions in your case study?Research processHardcase studyDED.E. ShawGeneralist · New York · 2025Houlihan LokeyInvestment Banking · Richmond · 2025

   Say this

   Each assumption should trace to something external: a historical rate, a disclosed contract, an industry data point, a peer's experience. Name the source for each, and say which ones you are least confident about.

   Then walk it

   1. Go through them in order of importance to the answer, not in model order. The interviewer cares about the two that drive the result.
   2. For each, give the anchor: 'I used 6 percent price growth because that is what they have taken in each of the last four years and the contracts reprice annually to an index.'
   3. Where you had no data, say so explicitly and explain the logic you substituted. Inventing a source is fatal; reasoning openly from a gap is respected.
   4. Distinguish the assumptions that matter from the ones that do not. 'The tax rate assumption is immaterial; the retention assumption drives 70 percent of the value' shows you understand your own model.
   5. Present the sensitivity around the critical ones rather than defending a point estimate. The honest position is a range with a most likely case.
   6. And volunteer your least confident assumption before they find it. Doing so converts a vulnerability into evidence of self-awareness.

   Where candidates lose it

   Defending every assumption equally, or saying 'that is what management guided'. Guidance is an input to be tested, not a source of truth. Trace assumptions to independent evidence wherever possible.

   Expect next

   • Which assumption are you least confident about?
   • What if that assumption is 20 percent wrong?
   • Where did you disagree with management's guidance?
