   Say this

   Buy a business mostly with debt, use its cash flow to pay that debt down, improve the operations, then sell in five years. The equity return comes from deleveraging, EBITDA growth and any change in the exit multiple.

   Then walk it

   1. Entry: agree a purchase price as a multiple of EBITDA, then build sources and uses. Debt goes in as far as the credit market will support, say five times EBITDA, and the sponsor funds the rest plus fees.
   2. Operating model for five years, then the debt schedule: interest, mandatory amortisation, and a cash sweep applying surplus cash to repay debt.
   3. Each year free cash flow after interest reduces debt, so the equity slice grows even with a flat enterprise value.
   4. Exit at an assumed multiple on final-year EBITDA, subtract remaining debt, and that is exit equity.
   5. Compute IRR and money multiple, then attribute the return across the three drivers. An investment committee will always ask which one carries the deal.
   6. The discipline point: if the return only works on multiple expansion, it is not a thesis, it is a market bet. I would want it to clear on deleveraging and EBITDA alone.

   Where candidates lose it

   Describing the mechanics without attributing the return. Every serious LBO answer ends with which of the three drivers produces the IRR and an acknowledgement that multiple expansion is the one you do not control.

2. 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?

   Reported by candidates at EQT (Infrastructure, Munich, 2013); TPG (Investment Banking, New York, 2024). Source: Wall Street Oasis.

3. 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?

4. 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.

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

5. 006Explain the fund structure: management fee, carry, hurdle and catch-up.Fund economicsHardtechnicalKohlberg Kravis RobertsInvestor Relations · New York · 2025

   Say this

   Classic terms are two and twenty over an eight percent hurdle. The manager takes 2 percent a year on committed capital, and 20 percent of profits, but only after investors have received their capital back plus an 8 percent preferred return.

   Then walk it

   1. Management fee: around 2 percent on committed capital during the investment period, often stepping down to invested capital afterwards. It funds the firm's operations, not the partners' upside.
   2. Preferred return or hurdle: usually 8 percent. Limited partners receive their capital back plus this return before the manager earns any carry.
   3. Catch-up: once the hurdle is met, the manager typically receives 100 percent of subsequent distributions until it has caught up to 20 percent of total profits. Then the split reverts to 80/20.
   4. Carried interest: the manager's 20 percent share of profits. This is where partners actually make money and why alignment is claimed.
   5. Clawback: if early distributions gave the manager carry that later losses erase, it must be returned. This is what makes the whole structure defensible over a fund's life.
   6. The distinction that matters: European waterfall distributes on a whole-fund basis, so carry is only paid once the entire fund clears the hurdle. American waterfall is deal-by-deal, so carry can be paid earlier. Limited partners strongly prefer the European version, and knowing which a firm uses is a real signal of preparation.

   Where candidates lose it

   Reciting 'two and twenty' without the hurdle, catch-up and clawback. Those three are what make the structure work, and the European versus American waterfall distinction is what separates a prepared candidate from a general one.

   Expect next

   • What is the difference between a European and American waterfall?
   • What is a clawback?
   • How would you highlight the fund to an endowment versus a fund of funds?

6. 007What makes a good LBO candidate?Investment judgementCorefirst roundWPWarburg PincusPrivate Equity · San Francisco · 2014Clayton Dubilier and RicePrivate Equity · London · 2026GSGuggenheim SecuritiesHealthcare · London · 2026

   Say this

   Predictable cash flow that can service debt, low capital intensity, a defensible market position, a clear operational improvement to make, and a credible exit. Stability matters more than growth.

   Then walk it

   1. Cash flow stability first, because debt service is non-negotiable. Contracted or recurring revenue, low cyclicality, sticky customers, and a demonstrated ability to hold margin through a downturn.
   2. Low maintenance CapEx, since every dollar spent on the asset base is a dollar not repaying debt.
   3. Defensible position: switching costs, scale, regulation, brand. Something that protects margin for the five years you own it without requiring you to outspend competitors.
   4. An identifiable value creation lever: an underinvested commercial function, a bloated cost base, a fragmented sector supporting a buy-and-build, or a non-core division to divest.
   5. A real exit. A deep strategic buyer list, or a listed peer group at a decent multiple. The best entry price is worthless if nobody will buy it from you in five years.
   6. And the anti-candidate, which is worth naming: high-growth, cash-burning, cyclical, capital-heavy. That can be an excellent investment and a terrible LBO, and knowing the difference is the point of the question.

   Where candidates lose it

   Putting high growth near the top. Growth consumes cash and cash service is the binding constraint. Saying that venture-style growth is the opposite of what an LBO structure wants shows you understand why the structure exists.

   Expect next

   • Pitch me a company that would be a great LBO candidate.
   • Why is high growth not necessarily good?
   • Would you invest in a company with negative sales growth?

7. 009Would you invest in a company with negative sales growth?Investment judgementHardtechnicalPlatinum EquityGeneralist · Los Angeles · 2014

   Say this

   Yes, if the cash flow is durable and the price reflects the decline. Plenty of private equity is made in declining industries, where the discipline is to buy cheap, take out cost, and pay the equity back through cash rather than growth.

   Then walk it

   1. Declining revenue is not disqualifying. What matters is whether cash flow is predictable and whether the decline rate is stable and forecastable.
   2. Distinguish managed decline from collapse. A business losing 2 to 3 percent of revenue a year with 25 percent margins and no CapEx is a bond with an equity kicker. One losing 20 percent a year is a liquidation.
   3. The model works differently: value comes from cash extraction and deleveraging, not from growth or multiple expansion. You underwrite to getting your money back through cash flow and dividends, and treat the exit as upside.
   4. Leverage must be sized to the declining EBITDA, not today's. Covenants set against current EBITDA will breach in year three if the decline continues, which is how these deals actually fail.
   5. Operationally the plan is cost, pricing and consolidation. Buying declining competitors and stripping their overhead is a well-established strategy in end-of-life industries.
   6. The exit is the hard part. Strategic buyers in a declining sector are scarce, so you should underwrite assuming a lower exit multiple than entry, and check that the deal still works.

   Where candidates lose it

   Reflexively saying no. This question is asked specifically by funds that do exactly these deals, and a candidate who cannot see the cash-extraction case has only learned the growth playbook. Say yes, then name the conditions.

   Expect next

   • How would you leverage it?
   • How do you exit a declining business?
   • What decline rate would be too fast?

8. 014How much would you pay for a security that returns two times your money on a 12 percent PIK with no compounding?Credit and financingHardtechnicalApollo Global ManagementGeneralist · New York · 2019

   Say this

   Work out how long it takes to double at 12 percent simple. With no compounding, the accrual is 12 percent of par each year, so you double in a little over eight years. Then discount that to whatever return you require.

   Then walk it

   1. No compounding means simple interest: 12 percent of the original principal accrues each year, so the balance reaches two times par after 100 divided by 12, which is 8.33 years.
   2. So the instrument pays 2.0 times at year 8.33 if you buy at par.
   3. Now discount at your target. At a 15 percent required return, the present value of 2.0 in 8.33 years is 2.0 divided by 1.15 to the power 8.33, which is roughly 0.63 times par.
   4. So you would pay around 63 cents on the dollar to earn 15 percent. At a 20 percent target the price drops to roughly 45 cents.
   5. Then the credit judgement, which is the real content: PIK means no cash comes in for eight years, so your entire return depends on the borrower surviving and being able to refinance the accreted balance at maturity. That balance will be twice what you lent.
   6. So I would want to see enterprise value coverage at maturity against that grown claim, not against today's. If the business cannot support twice the debt in eight years, the security is worth far less than the arithmetic suggests.

   Where candidates lose it

   Treating it as compounding, which gives about six years instead of eight, or stopping at the arithmetic without the credit judgement. The point of a PIK question is the accreting claim and the refinancing risk at maturity.

   Expect next

   • What if it compounded?
   • What coverage would you need at maturity?
   • Does PIK increase or decrease enterprise value?

9. 015Why are shareholder loans used in a capital structure instead of just cash equity?Credit and financingHardtechnicalNUNuveenPrivate Equity · London · 2024

   Say this

   Mainly tax and flexibility. Interest on a shareholder loan is deductible where equity dividends are not, and a loan can be repaid without the formalities and restrictions that apply to returning share capital.

   Then walk it

   1. Tax efficiency is the primary driver: interest accrued to the sponsor's loan reduces taxable profit at the operating company, creating a shield that pure equity does not.
   2. Repayment flexibility: loan principal and accrued interest can be repaid as cash allows, whereas returning share capital often requires distributable reserves and legal formalities.
   3. Ranking and structuring: shareholder loans sit above equity in the waterfall, which matters when there are multiple equity holders, minority co-investors or management shareholders with different entry points.
   4. Allocation between investors: a loan with a fixed accrual gives the sponsor a preferred return ahead of the ordinary equity, which is how management's incentive equity gets structured to only pay out above a hurdle.
   5. The constraints to name: thin capitalisation rules, interest deductibility caps, and transfer pricing rules on the rate charged. Many jurisdictions have tightened these considerably, and the EU's anti-tax-avoidance rules limit the benefit.
   6. This is standard in European buyouts and infrastructure, and less so in the US, which is worth flagging since the structure is jurisdiction-dependent.

   Where candidates lose it

   Answering only 'it is tax efficient'. The ranking and the role in allocating returns between sponsor and management equity are the structuring content, and naming thin capitalisation rules shows you know the limits.

   Expect next

   • What limits the tax benefit?
   • How does this interact with management's incentive equity?
   • Walk me through an SPV model.

10. 016Walk me through an SPV or holding company model.LBO mechanicsHardtechnicalNUNuveenPrivate Equity · London · 2024

    Say this

    Model the operating asset first, then layer the holding structure on top: cash flows rise from the asset through the acquisition vehicle, paying debt at each level in order, and whatever reaches the top is the sponsor's return.

    Then walk it

    1. Build the asset-level model: revenue, costs, taxes, CapEx and working capital, producing operating cash flow available for debt service.
    2. Then the asset-level or senior debt: interest, amortisation, and the debt service cover ratio. Lock-up tests at this level determine whether cash can move upward at all, which is the key structural feature.
    3. Cash that passes the tests distributes up to the holding company. There it services any holdco debt or shareholder loan, which is structurally subordinated because it sits behind the operating company's lenders.
    4. Whatever remains is distributable to the sponsor, so the equity return is computed on distributions received rather than on accounting profit.
    5. Model the tax and the group structure explicitly: where the deductions arise, whether losses can be surrendered between entities, and withholding on cross-border payments.
    6. The output is an equity IRR on the sponsor's cash flows, with the distribution lock-up tests as the thing to sensitise. In infrastructure especially, a covenant breach does not mean default, it means the cash stops flowing upward, and that alone can destroy the equity return.

    Where candidates lose it

    Modelling it as a single-entity LBO. The distinctive content is structural subordination and the distribution lock-up tests that trap cash at the operating company. Those tests are usually what breaks the equity case.

    Expect next

    • What is structural subordination?
    • What happens if the DSCR test is breached?
    • Why do infrastructure deals use this structure?
