   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?

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. 004Do a paper LBO. EBITDA of $100, bought at 10 times, five turns of leverage, exit at the same multiple in five years with EBITDA at $150.LBO mechanicsHardtechnicalBain CapitalGeneralist · Boston · 2024WPWarburg PincusPrivate Equity · New York · 2014Clayton Dubilier and RicePrivate Equity · London · 2026

   Say this

   Entry equity is $500. With about $250 of debt repaid over five years, exit equity is $1,500 less $250, so $1,250. That is 2.5 times the money and roughly a 20 percent IRR.

   Then walk it

   1. Entry: $100 EBITDA at 10 times is $1,000 enterprise value. Debt at five turns is $500, so the sponsor writes $500.
   2. Cash generation: EBITDA ramps from $100 to $150, averaging about $125. Interest on $500 at 8 percent is roughly $40. Less CapEx of $25, working capital of $5, and cash taxes on EBIT.
   3. That leaves around $50 a year to sweep, so about $250 of debt repaid. Ending debt is $250.
   4. Exit: $150 at 10 times is $1,500, less $250 of debt, equals $1,250 of equity.
   5. Return: $1,250 on $500 is 2.5 times. Using the standard grid, 2.0 times over five years is about 15 percent, 2.5 times is about 20 percent, 3.0 times is about 25 percent.
   6. Attribution: EBITDA grew 50 percent and debt halved, with no multiple expansion assumed. That is the version an investment committee likes, because the return does not depend on the exit market.

   Where candidates lose it

   Reaching for a calculator or chasing decimal precision. Round hard, state every assumption out loud, and know the IRR grid cold. Also announce your interest rate and CapEx assumptions rather than letting them appear silently.

   • What if you exit at 8 times?
   • What return does the fund actually need?
   • How much of that return came from each driver?

5. 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?

6. 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?

7. 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?

8. 008Pitch me a business that would be a great LBO candidate, covering market drivers and both financial and non-financial qualities.Investment judgementHardsuperdayClayton Dubilier and RicePrivate Equity · London · 2026GSGuggenheim SecuritiesHealthcare · London · 2026

   Say this

   Pick a real company, ideally mid-cap and slightly unglamorous, and structure it as: why the market works, why this asset wins in it, what you would do differently as owner, how you would fund it, and how you would exit.

   Then walk it

   1. Market first: growing or at least stable demand, fragmented enough to consolidate, with a driver you can name, regulation, outsourcing, demographics, infrastructure spend.
   2. Then the asset: recurring revenue, contracted or repeat, gross margin stability, customer concentration low enough to be safe, and a defensible position you can describe in one sentence.
   3. Then the value creation plan, which is the part most candidates skip. Be specific: pricing that has not been touched in years, a sales force with no CRM discipline, three acquirable competitors in adjacent geographies, a non-core division to sell.
   4. Then the financing: what leverage the cash flow supports, what the interest burden looks like, and whether covenants would be comfortable in a downside case.
   5. Then the exit: who buys it in five years and why. Name actual acquirers, and say what the asset would look like at exit compared with today.
   6. Then the risks and what would stop you. A pitch with no acknowledged risk reads as a sales document rather than an investment case.

   Where candidates lose it

   Pitching a household name that is far too large or obviously not leveragable. Pick something with a realistic enterprise value for the fund you are interviewing with, and lead with the value creation plan rather than the financials.

   Expect next

   • How much leverage would it support?
   • Who buys it from you in five years?
   • What is the biggest risk?

9. 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?

10. 010Here are the financial statements of three companies with no names. Tell me what type of business each one is.Investment judgementHardtechnicalHPS Investment PartnersSpecial Situations · London · 2021

    Say this

    Read the structure, not the numbers. Gross margin, asset intensity and working capital give away the business model almost immediately, and each combination points to a specific type of company.

    Then walk it

    1. High gross margin, negligible inventory, large deferred revenue, heavy R&D and sales spend: software.
    2. Low gross margin, high inventory, high fixed assets, thin net margin: manufacturing, distribution or retail. Split them by inventory turns and receivables. Retail collects immediately so receivables are near zero; distribution carries both inventory and receivables.
    3. Very high fixed assets, high depreciation, high debt, stable margins: utilities, telecom or infrastructure.
    4. Large receivables, no inventory, high staff cost as a share of revenue: a services or consulting business.
    5. Negative working capital, meaning payables exceed receivables and inventory: a business collecting from customers before paying suppliers, so restaurants, supermarkets, subscriptions or airlines.
    6. The systematic way to run it out loud: common-size everything as a percentage of revenue, look at the three biggest lines, compute working capital days, then name the model and say what evidence drove the conclusion. Getting the reasoning visible matters more than being right on all three.

    Where candidates lose it

    Guessing silently. This tests whether you can read a set of accounts structurally. Narrate the ratios you are computing and what each rules out; the process is being graded more than the identification.

    Expect next

    • Which of them would you lend to?
    • Which would make the best LBO?
    • What working capital profile would you want as an owner?
