1. 002How does private equity create value?Value creationIntermediatefirst roundEQTInfrastructure · Munich · 2013TPTPGInvestment Banking · New York · 2024

   Say this

   Three financial levers, deleveraging, EBITDA growth and multiple expansion, sitting on top of two real ones: operational improvement and better governance. The financial levers are the arithmetic; the operational ones are the actual work.

   Then walk it

   1. Deleveraging: cash flow repays debt, so enterprise value transfers from lenders to the equity. At five times leverage this alone can double equity over a hold with no growth.
   2. EBITDA growth: organic revenue, pricing, cost programmes, and bolt-on acquisitions. Bolt-ons are especially powerful because buying at six times into a platform valued at twelve creates value on announcement.
   3. Multiple expansion: selling higher than you bought, either because the market moved or because you made the asset genuinely better, larger, more diversified, more recurring.
   4. Underneath those: operational improvement. Professionalising a founder-run business, installing proper reporting, fixing pricing, rationalising the portfolio, upgrading management.
   5. And governance. A concentrated owner with board control and aligned management incentives makes decisions faster than a public company answering to a diffuse shareholder base. That alignment is a genuine structural advantage, not just a story.
   6. The honest framing: in the 2010s a lot of the industry's returns came from cheap debt and rising multiples. With both less available, the operational lever is where the differentiation now has to come from, and every fund will say this in its fundraising deck.

   Where candidates lose it

   Answering only 'leverage'. Leverage amplifies returns, it does not create them, and a sponsor interviewer will push back hard. Name the operational and governance levers and acknowledge that the easy financial tailwinds have gone.

   Expect next

   • Which lever matters most today?
   • What would you do in the first hundred days?
   • What is better, a dollar of EBITDA or a dollar less debt?

2. 003What is better: a one dollar increase in EBITDA or a one dollar decrease in debt?Value creationIntermediatetechnicalAMAres ManagementPrivate Equity · New York · 2026

   Say this

   A dollar of EBITDA, by the exit multiple. If you exit at 10 times, one extra dollar of EBITDA is ten dollars of enterprise value, while a dollar of debt repaid is one dollar of equity. Ten to one.

   Then walk it

   1. Debt paydown is a one-for-one transfer: a dollar less debt is a dollar more equity at exit.
   2. EBITDA is capitalised at the exit multiple. At 10 times, a permanent extra dollar of EBITDA adds ten dollars of enterprise value and therefore ten dollars of equity.
   3. So the ratio is simply the exit multiple, which is a clean way to say it and shows you understand the mechanism rather than the answer.
   4. The conditions that matter: the EBITDA has to be recurring, not a one-off, and the multiple has to hold. A dollar of EBITDA from a one-time contract is worth roughly a dollar, not ten.
   5. There is also a second-order benefit: higher EBITDA reduces the leverage ratio at the same debt level, which improves covenant headroom and refinancing options.
   6. The nuance worth adding: early in a hold, when leverage is high and covenants are tight, a dollar of debt repayment can be worth more than its face value because it buys flexibility and avoids a default. So the answer is EBITDA in general, debt paydown when survival is the issue.

   Where candidates lose it

   Answering without naming the exit multiple as the exchange rate. That one insight is the whole question. Also missing that the EBITDA must be recurring for the multiple to apply.

   Expect next

   • What if the EBITDA is a one-off?
   • When would you prefer the debt repayment?
   • How does that change how you prioritise the value creation plan?

3. 005What return does a private equity fund actually need, and why?ReturnsIntermediatetechnicalWPWarburg PincusPrivate Equity · New York · 2014

   Say this

   Roughly 20 to 25 percent gross IRR on a deal, which after fees and carry delivers something in the mid to high teens net to investors. The gross target has to clear the fee load and compensate for illiquidity.

   Then walk it

   1. The deal-level hurdle is typically a 20 to 25 percent gross IRR and a 2.5 to 3 times money multiple over roughly five years.
   2. Why that high: limited partners could buy public equities for nothing, so private equity has to beat that by enough to justify a ten-year lock-up, no liquidity and a 2 percent management fee plus 20 percent carry.
   3. The fee drag is substantial. Gross to net can lose five hundred basis points or more, so a 20 percent gross deal is a mid-teens net return.
   4. There is also a preferred return, usually 8 percent, below which the manager earns no carry at all. That sets a hard floor on what is worth doing.
   5. And not every deal works. If one in five is written off, the survivors have to carry the fund, so underwriting to a bare hurdle leaves no margin for the portfolio.
   6. The structural point worth making: as fund sizes have grown and entry multiples risen, realistic target returns have compressed, which is why operational value creation matters more now than it did when leverage and multiple expansion did the work.

   Where candidates lose it

   Quoting a number with no explanation of why it is that high. The examinable content is the fee load, the illiquidity premium and the portfolio effect where losers must be carried by winners.

   Expect next

   • What is a preferred return?
   • How does the fee structure work?
   • Why have target returns compressed?

4. 023What would make you walk away from a deal in diligence?Due diligenceIntermediatetechnicalAdvent InternationalPrivate Equity · Boston · 2022

   Say this

   Anything that breaks the thesis rather than just the price. Integrity problems, undisclosed liabilities, or discovering that the earnings are not what they appeared. Most other findings are price adjustments.

   Then walk it

   1. Integrity issues are absolute: evidence of misrepresentation, undisclosed related-party dealing, or a management team that has been misleading. You cannot own a business with people you cannot trust, and no discount compensates.
   2. Earnings that are not real: quality of earnings revealing that adjusted EBITDA is materially overstated, or revenue recognition that pulls forward future periods.
   3. Concentration you cannot mitigate: a single customer at 40 percent of revenue with a contract expiring in a year, and no ability to speak to them before closing.
   4. Structural market deterioration discovered in commercial diligence: substitution, a regulatory change, a competitor's product that changes the economics.
   5. Then the distinction that matters: most findings are price and structure issues, not deal-breakers. A pension deficit or an environmental liability can be handled with an indemnity, an escrow or a price cut.
   6. So my framing would be: if the finding changes the value, we renegotiate. If it changes whether the business is what we thought it was, or who we would be in business with, we walk.

   Where candidates lose it

   Listing findings without the price-versus-thesis distinction. Sponsors renegotiate constantly and walk rarely, so the judgement being tested is knowing which category a finding falls into.

   Expect next

   • How would you renegotiate rather than walk?
   • What is an escrow for?
   • Have you ever been on a deal that broke?

5. 024How do you think about customer concentration?Due diligenceIntermediatetechnicalHWHarris WilliamsInvestment Banking · Richmond · 2025

   Say this

   It is a risk you price rather than one you avoid, and the question is not the percentage but the strength of the relationship. A twenty-year sole-source relationship at 40 percent is very different from a tendered contract at 40 percent.

   Then walk it

   1. First the numbers: top customer, top five and top ten as a percentage of revenue and of gross profit. Gross profit concentration is often worse than revenue concentration and nobody looks at it.
   2. Then the relationship quality: contract length and notice period, whether you are sole source or one of several, how embedded you are in their process, and what it would cost them to switch.
   3. Then tenure and trajectory: a customer of fifteen years whose spend is growing is a very different risk from one recently won on price.
   4. Then the customer's own health, because their problems become yours. And whether they are themselves consolidating, which changes the negotiating balance.
   5. Mitigations: customer reference calls during diligence, contractual protections, price adjustments, earn-outs tied to retention, or a specific indemnity.
   6. The effect on exit matters too: concentration reduces the buyer universe and the multiple at your own exit, so you pay for it twice. That is the point most candidates miss.

   Where candidates lose it

   Treating concentration as a simple threshold. The substance is relationship durability and switching cost. And the exit-multiple consequence, that you pay for concentration again when you sell, is the sophisticated addition.

   Expect next

   • What would you ask in a customer call?
   • How would you structure around it?
   • How does it affect the exit multiple?

6. 025What are the key drivers of value creation in a deal, and how do you attribute the return?Value creationIntermediatetechnicalTPTPGInvestment Banking · New York · 2024

   Say this

   Break the equity gain into revenue growth, margin improvement, multiple change and deleveraging. The attribution bridge is a standard exhibit in every exit review and every fundraising deck.

   Then walk it

   1. Start with entry and exit equity values, then decompose the change.
   2. Revenue growth contribution: hold margin and multiple constant, and measure the EBITDA change from volume and price alone.
   3. Margin contribution: hold revenue constant and measure the EBITDA change from margin improvement. Splitting these two matters because they say different things about the quality of the work.
   4. Multiple contribution: change in exit multiple times exit EBITDA. This is the component the fund does not control and the one limited partners discount.
   5. Deleveraging contribution: the reduction in net debt over the hold, which flows straight to equity.
   6. The interpretation is what matters: a fund whose returns come predominantly from multiple expansion has been lucky and will say it was skill. A fund whose returns come from margin and revenue has actually done something. In a fundraising conversation, that attribution is the single most scrutinised chart.

   Where candidates lose it

   Naming the drivers but being unable to build the bridge. Also failing to separate revenue from margin, which collapses the two very different value creation stories into one.

   Expect next

   • Which component would a limited partner discount?
   • How would you build that bridge in Excel?
   • Which driver has been most important for the industry over the last decade?

7. 026What is multiple arbitrage and how does a buy-and-build strategy work?Value creationIntermediatetechnicalAudax GroupPrivate Equity · Boston · 2021

   Say this

   Buy small companies at low multiples into a platform that is valued at a higher multiple. Six times EBITDA bought inside a business worth twelve times creates value on completion, before any synergy.

   Then walk it

   1. The mechanism: smaller companies trade at lower multiples because they are riskier, less liquid and have fewer buyers. A larger platform trades higher. Moving EBITDA from one to the other closes that gap.
   2. So acquiring a business at six times that is immediately valued at your platform's twelve times doubles the value of that EBITDA with no operational change at all.
   3. Add cost synergies on top, removing duplicated overhead, and the effective entry multiple falls further, often to four or five times post-synergy.
   4. The strategy also grows the platform, and scale itself can support a higher exit multiple by improving diversification, management depth and buyer appeal.
   5. The risks are real and worth naming: integration capacity, paying up as a sector gets competitive, and roll-ups that grow EBITDA while destroying organic growth. A buyer at exit will look hard at organic performance excluding acquisitions.
   6. And the financing constraint: each acquisition needs funding, so the platform's leverage and lender relationships determine how fast you can execute.

   Where candidates lose it

   Describing the arbitrage as if it were free money. The exit buyer sees through a roll-up with no organic growth, and diligence at exit will strip out acquired growth. Naming that shows you understand both ends of the trade.

   Expect next

   • What does a buyer at exit look at in a roll-up?
   • How do you fund a bolt-on programme?
   • How much of the synergy would you pay away?

8. 028How do you think about leverage levels, and what determines how much debt a business can take?Credit and financingIntermediatetechnicalLazardGeneralist · Amsterdam · 2025

   Say this

   Cash flow, not EBITDA. The test is whether the business can service interest and mandatory amortisation in a downside case with headroom left over. Lenders express that as leverage and coverage multiples.

   Then walk it

   1. The headline metrics: net debt to EBITDA and EBITDA to interest. In a normal market a stable mid-market business might support four to six times, a cyclical one less, a contracted infrastructure asset far more.
   2. But the real constraint is free cash flow after CapEx and working capital. Two businesses with identical EBITDA and different capital intensity support very different debt loads.
   3. Test it in the downside: model a 20 percent EBITDA decline and check whether covenants hold and whether interest is still covered. That downside test is what determines the structure, not the base case.
   4. Sector and cyclicality matter enormously. Lenders will fund a software business with recurring revenue at leverage they would never accept for a construction business.
   5. Market conditions set the ceiling independently of the credit. In a tight market the same business raises a turn or two less, regardless of its quality.
   6. And the sponsor's own judgement: more leverage raises IRR and raises the chance of losing the equity entirely. The optimisation is not maximum debt, it is the level that survives the downside you can actually imagine.

   Where candidates lose it

   Answering purely in EBITDA multiples. The underlying constraint is free cash flow and downside resilience. Naming the covenant test in a stressed case is what makes the answer sound like someone who has underwritten a deal.

   Expect next

   • What is the difference between incurrence and maintenance covenants?
   • How does private credit change what is available?
   • How much cushion would you want in a covenant?

9. 037If a company raises $100 of debt to buy back $100 of shares, what happens to enterprise value and equity value?ValuationIntermediatetechnicalSilver LakeTechnology, Media and Telecom · San Francisco · 2022

   Say this

   Enterprise value is unchanged, because the operating business did not change. Equity value falls by $100 and net debt rises by $100, so the two offset exactly.

   Then walk it

   1. Enterprise value is the value of the operating assets. Issuing debt and retiring stock rearranges the claims on those assets without touching them.
   2. Equity value falls by the $100 spent on the buyback. Net debt rises by the $100 raised. EV equals equity plus net debt, so it is unchanged.
   3. Share count falls, so value per share need not fall. If the buyback was executed at fair value, per-share value is unchanged; above fair value it destroys per-share value, below it creates it.
   4. The second-order effects are where it gets interesting: the tax shield on the new debt adds some value, while higher leverage increases distress risk and the cost of equity. In the Modigliani-Miller frame with taxes, the tax shield dominates at moderate leverage.
   5. EPS usually rises because the share count fell more than net income did, but as always that is arithmetic rather than value creation.
   6. So the clean answer: EV flat, equity down $100, net debt up $100, per-share value depends entirely on the price paid.

   Where candidates lose it

   Saying enterprise value falls because debt went up. Debt is part of the bridge, not part of enterprise value. This is the single most common enterprise value misunderstanding and it gets tested constantly.

   Expect next

   • What happens to value per share?
   • When is the buyback value-destructive?
   • What happens to WACC?

10. 040What metrics would you look at when valuing a retail company?Sector knowledgeIntermediatetechnicalSilver LakeTechnology, Media and Telecom · San Francisco · 2022

    Say this

    Same-store sales decomposed into traffic and ticket, gross margin, sales per square foot, inventory turns, and the four-wall economics of a store. Then lease liabilities, because that is where retail leverage hides.

    Then walk it

    1. Comparable store sales is the quality signal, because total revenue growth can be manufactured by opening stores. Break it into transactions and average ticket, and ticket into units and price.
    2. Gross margin trend against comps tells you whether sales are being bought with discounting.
    3. Sales per square foot and four-wall EBITDA, meaning store-level profit before corporate overhead. That determines whether new stores create value and what the payback period on a new store is.
    4. Inventory turns and the inventory-to-sales relationship. Inventory building faster than sales is the earliest reliable warning of markdowns to come.
    5. Online mix and its profitability, including returns and delivery cost, because e-commerce margin is often far worse than the store channel once fulfilment is loaded.
    6. For a sponsor specifically: the lease portfolio. Rent is a fixed obligation and the lease liability behaves like debt, so a retailer with a long lease estate is far more levered than its net debt suggests. And the real estate itself may be worth more than the operating business, which changes the whole thesis.

    Where candidates lose it

    Giving generic metrics with no retail specificity. Four-wall economics, inventory turns and the lease liability are the three that mark out someone who has looked at a retail deal.

    Expect next

    • How do you treat lease liabilities in leverage?
    • What is four-wall EBITDA?
    • Would you rather own the real estate or the operating company?
