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. 019Why do you unlever and relever beta, and why does it matter?ValuationIntermediatetechnicalHWHarris WilliamsInvestment Banking · Los Angeles · 2025

   Say this

   Observed beta reflects both the business risk and the leverage of each peer. You unlever to strip out their capital structures so you are comparing pure business risk, then relever at your target's structure.

   Then walk it

   1. Pull raw betas for the peer set. Each one is contaminated by that company's own debt load.
   2. Unlever each: asset beta equals equity beta divided by one plus one minus tax times debt over equity. Now you have pure business risk.
   3. Take the median or mean of the unlevered betas. Median is safer because one over-levered peer can drag a mean badly.
   4. Relever at your target's capital structure, or its target structure if you expect it to change.
   5. It matters because skipping it means you have imported someone else's leverage into your cost of equity. In an LBO, where structure changes by design, getting this wrong makes the whole discount rate meaningless.

   Where candidates lose it

   Knowing the formula but not the purpose. If asked 'why does it matter', the answer is comparability of business risk. Say that first, then the mechanics.

   Expect next

   • Would you use median or mean of the unlevered betas?
   • What is the beta of a slot machine?
   • How would you get a beta for a private company?

3. 022Rank the valuation methodologies from highest to lowest and explain why.ValuationIntermediatesuperdayNomuraInvestment Banking · New York · 2026

   Say this

   The usual ordering is precedent transactions highest, then DCF, then trading comps, with an LBO analysis lowest. But I would say upfront that this is a tendency, not a rule, and I can construct cases where it inverts.

   Then walk it

   1. Precedents sit highest because they include a control premium and often synergies a strategic buyer was willing to pay for.
   2. DCF usually sits above trading comps because sell-side forecasts tend to be optimistic, and because you are capturing the full life of the cash flows.
   3. Trading comps reflect minority stakes with no control, so they exclude the premium.
   4. LBO analysis is normally the floor, because a sponsor needs a target return and cannot pay for synergies it does not have.
   5. The inversions are the interesting part. In a frothy market, trading comps can exceed precedents from a downturn. And a strategic with real cost synergies can beat any sponsor, which is why the sponsor floor is not always the floor.

   Where candidates lose it

   Delivering the ranking as gospel. Interviewers ask this specifically to see whether you understand the logic or memorised a ladder. Name the ordering, give the reason for each rung, then volunteer a case where it flips.

   Expect next

   • Give me a case where trading comps exceed precedents.
   • Would Blackstone or Nike pay more to acquire Adidas?
   • Who typically pays more, a sponsor or a strategic?

4. 023Where is the premium baked in in precedent transactions?ValuationIntermediatetechnicalUBSInvestment Banking · New York · 2026

   Say this

   In the numerator. The transaction value is the price actually paid to take control, which already includes whatever premium the buyer offered over the unaffected share price, so the resulting multiple is a control multiple.

   Then walk it

   1. You build the multiple as transaction enterprise value over the target's EBITDA at the time. The EV is based on the offer price, not the pre-deal trading price.
   2. So the premium is inside the numerator and therefore inside the multiple itself. You do not add a premium on top afterwards.
   3. That is exactly why precedent multiples run above trading multiples for the same sector.
   4. The measurement subtlety: you compute the premium against the unaffected price, typically one day and thirty days before the first leak or announcement, not against the price after the rumour has already moved the stock.
   5. And the practical caution: if the precedent included large buyer-specific synergies, that multiple overstates what a financial buyer would pay for your client.

   Where candidates lose it

   Applying a control premium on top of a precedent transaction multiple. That double-counts and it is a genuine analyst error, not just an interview slip. Say explicitly that the premium is already in the multiple.

   Expect next

   • Against what price do you measure the premium?
   • Why do precedent multiples exceed trading multiples?
   • How stale is too stale for a precedent?

5. 024Walk me through how you would find comps and precedents for a company.ValuationIntermediatetechnicalEvercoreInvestment Banking · Menlo Park · 2025

   Say this

   Start from what the business actually does and who it competes with, then screen on size, growth, margin and geography. For precedents, screen deals in the same sub-sector over the last three to five years, then throw out the ones with special circumstances.

   Then walk it

   1. First pass on business model, not SIC code. A software company selling to hospitals belongs with healthcare IT, not with enterprise software generally.
   2. Practical sources: the target's own filings name its competitors, equity research initiation reports carry a comp set, and any prior deal in the space has a fairness opinion with a comp list in it.
   3. Then screen for comparability on scale, growth rate, margin profile and end-market mix. A company growing 30 percent does not belong with one growing 3 percent, whatever the sector.
   4. For precedents, filter on date, size and deal type, and separate strategic buyers from sponsors, because they pay differently.
   5. Last step is the judgement call: exclude distressed sales, minority stakes and deals with unusual structures, and be ready to defend every exclusion, because the client will ask.

   Where candidates lose it

   Saying 'I would pull them from Capital IQ' and stopping. The screen is the easy part; the defensible judgement about who belongs in the set is the job. Name your inclusion criteria and your exclusions.

   Expect next

   • How many comps is the right number?
   • Your best comp trades at a huge premium to the rest. What do you do?
   • Build me a buyer universe for this company.

6. 026What happens to the EV/EBITDA multiple when EBITDA increases?ValuationIntermediatetechnicalJefferiesInvestment Banking · New York · 2025

   Say this

   Mechanically the multiple falls, because the denominator grew and enterprise value is fixed at a point in time. But that is only true for an instant, because in a real market EV would move too.

   Then walk it

   1. Holding EV constant, a bigger denominator means a smaller multiple. That is just arithmetic.
   2. In reality, if EBITDA rises because the business genuinely improved, the market re-rates the equity and EV rises, often more than proportionally if growth expectations improve.
   3. So the multiple could stay flat or even expand, depending on why EBITDA moved.
   4. If EBITDA rose for a low-quality reason, say a one-off gain or an accounting change, EV should not move and the multiple genuinely compresses.
   5. The useful framing: the multiple is an output, not an input. Ask what caused the EBITDA change and the answer follows.

   Where candidates lose it

   Giving only the mechanical answer and looking pleased. The interviewer is waiting to see whether you notice that EV is not actually constant. Give both layers, and the 'why did EBITDA move' framing.

   Expect next

   • So is the multiple an input or an output?
   • What if EBITDA rose because of a one-time gain?
   • How would you adjust EBITDA for quality?

7. 027How does EV/EBITDA vary across industries, and where is it larger or smaller?ValuationIntermediatetechnicalTSTruist SecuritiesInvestment Banking · New York · 2026

   Say this

   High multiples go to businesses with durable growth, high returns on capital and low reinvestment needs, so software and branded consumer sit at the top. Low multiples go to cyclical, capital-hungry, low-growth businesses like steel, airlines and utilities.

   Then walk it

   1. Software trades high because incremental revenue costs almost nothing to serve, revenue is recurring, and CapEx is minimal. Twenty times and above is normal.
   2. Branded consumer and medical devices sit in the mid to high teens on pricing power and stable demand.
   3. Industrials and distribution sit around eight to twelve, reflecting moderate growth and real capital needs.
   4. Cyclicals and capital-intensive businesses sit low, often four to seven, because earnings are volatile and most of the EBITDA gets reinvested just to stand still.
   5. The unifying logic is that EV/EBITDA is a shorthand for growth, risk and reinvestment. High multiple means the market expects EBITDA to grow and to convert into cash. Steel fails both tests.

   Where candidates lose it

   Reciting sector multiples as trivia without the underlying driver. If you cannot explain why software earns twenty times and steel earns five, you have memorised a table. The answer is cash conversion and growth durability.

   Expect next

   • Which company would have a higher multiple, asset-heavy or asset-light?
   • What is an appropriate multiple for software?
   • A company in your sector trades at half the peer multiple. Why?

8. 028Which company would have a higher multiple, an asset-heavy company or an asset-light one?ValuationIntermediatetechnicalBarclaysInvestment Banking · London · 2026

   Say this

   Asset-light, normally, on EV/EBITDA. It converts more of its EBITDA into free cash flow because it does not have to spend heavily just to maintain the asset base, and it can grow without proportional capital.

   Then walk it

   1. Asset-light means low maintenance CapEx, so a higher share of EBITDA reaches free cash flow. Buyers pay for cash, not for EBITDA.
   2. It also means higher return on invested capital and the ability to scale without a matching balance sheet, which supports a growth premium.
   3. The mechanical wrinkle worth flagging: asset-heavy companies have large D&A, which inflates EBITDA relative to EBIT. So their EV/EBITDA looks artificially low while their EV/EBIT looks more normal.
   4. That is why comparing the two on EV/EBITDA alone is misleading, and why I would pull EV/EBIT or EBITDA less CapEx as well.
   5. The exception: an asset-heavy business with a genuinely protected asset, like a toll road or a regulated utility with a rate base, can command a high multiple precisely because the assets are the moat.

   Where candidates lose it

   Answering 'asset-light' with no mechanism. And missing the D&A point, which is the technically interesting half: part of the multiple gap is real economics and part is just an accounting artefact of EBITDA.

   Expect next

   • So how would you compare them fairly?
   • How would you value an airline that leases its fleet versus one that owns it?
   • Where does a toll road fit in your answer?

9. 035How would you value a telco versus a software company?ValuationIntermediatetechnicalCSCredit SuisseInvestment Banking · Sydney · 2020

   Say this

   The telco is a capital-intensive, low-growth cash cow, so you value it on EV/EBITDA and EV/EBITDA less CapEx, and you care about the dividend. The software company is asset-light and growth-driven, so you value it on revenue multiples adjusted for growth and retention.

   Then walk it

   1. For the telco, EBITDA is large but so is CapEx on spectrum and network, so EV/EBITDA alone flatters it. EV/EBITDA less CapEx, or EV/EBIT, is the honest read.
   2. Telco value is also driven by regulation, spectrum holdings and subscriber metrics like ARPU and churn. A DCF works well because the cash flows are predictable.
   3. For the software company, current earnings are suppressed by growth spending, so EV/EBITDA is close to meaningless. EV/revenue against growth rate is the working metric.
   4. The quality tests for software are net revenue retention, gross margin and the rule of forty, growth plus margin. Those determine whether a revenue multiple is deserved.
   5. So both get a DCF, but the telco DCF is credible on near-term cash flows while the software DCF is almost entirely terminal value. That difference is the real answer: you trust the telco's forecast and you stress-test the software company's.

   Where candidates lose it

   Treating it as a list of two metric sets. The interviewer wants you to notice that the DCF is reliable for one and mostly assumption for the other. That structural insight is the answer.

   Expect next

   • What is the rule of forty?
   • What is the formula for net revenue retention, gross retention and churn?
   • Which would you rather own at today's multiples?
