1. 016What are the main drivers or sensitivities in a DCF?ValuationIntermediatetechnicalTD SecuritiesInvestment Banking · New York · 2026Moelis & CompanyInvestment Banking · New York · 2026

   Say this

   The discount rate and the terminal value assumption, by a wide margin. After those, the revenue growth and margin path in the forecast years, then CapEx and working capital intensity.

   Then walk it

   1. WACC dominates because it compounds. A 100 basis point move in WACC can swing value 15 to 20 percent for a long-duration business.
   2. Terminal value is the other big one, since it is usually 60 to 80 percent of enterprise value. A 50 basis point change in perpetuity growth moves the answer materially.
   3. Inside the forecast, margin matters more than revenue for most mature businesses, because a margin point drops straight to cash.
   4. CapEx and working capital intensity matter most for capital-hungry or fast-growing companies, where growth consumes cash.
   5. The standard output is a two-way sensitivity table, WACC against exit multiple or against perpetuity growth. That grid is what actually goes in the deck, not a single point value.

   Where candidates lose it

   Listing revenue growth first. It feels intuitive but it is wrong for most businesses; discount rate and terminal value swamp it. Also, saying 'a DCF gives you the intrinsic value' as if it were one number, rather than a range you present as a football field.

   Expect next

   • Given a $10 change in revenue, COGS, or CapEx, which has the biggest impact?
   • How do you pick the perpetuity growth rate?
   • What would you do if the DCF value is miles above the trading price?

2. 043Walk me through a deal you have been following, and tell me how it changed the industry.Markets and dealsIntermediatetechnicalBarclaysInvestment Banking · New York · 2023EvercoreInvestment Banking · Menlo Park · 2025Moelis & CompanyInvestment Banking · London · 2026WBWilliam BlairInvestment Banking · Atlanta · 2026

   Say this

   Pick one deal, know it cold, and tell it as a story with a number in every sentence: who bought whom, for how much, at what multiple, funded how, and why it made strategic sense.

   Then walk it

   1. Open with the facts in one breath: acquirer, target, enterprise value, the multiple paid, the premium to the undisturbed price, and the funding mix.
   2. Then the strategic rationale in one sentence. What did the buyer get that it could not build, and what synergies did it guide to?
   3. Then your own view, which is the part that matters. Was the price defensible? I would say something like: at fourteen times EBITDA against a peer set at eleven, the buyer needed the full guided synergies to justify it, so the deal is really a bet on integration.
   4. Then the industry effect: did it trigger consolidation, did it force a competitor response, did it change how the sector is valued?
   5. Pick a deal in the group you are interviewing with, and pick one where you have an actual opinion. A deal you can only describe is worse than a smaller deal you can argue about.

   Where candidates lose it

   Choosing the biggest headline deal and only reciting what the press release said. If you cannot say what multiple was paid and whether you think it was too much, you have not followed the deal, you have read about it.

   Expect next

   • Was the price too high?
   • If you were the buyer, what would you have worried about in diligence?
   • Who else could have bought it?
