1. 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.

   Expect next

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

2. 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?

3. 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?

4. 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?

5. 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?

6. 011Give me a purchase price for this company, given that the acquisition will generate an extra million of EBITDA.ValuationHardtechnicalAudax GroupPrivate Equity · Boston · 2021

   Say this

   Price the standalone business on its own multiple, then decide how much of the synergy you are willing to hand to the seller. In a buy-and-build you want to pay for the asset as it is and keep the synergy for yourself.

   Then walk it

   1. Start with standalone value: the target's own EBITDA at a multiple appropriate to its size and quality. Small bolt-ons trade well below platform multiples, often six to eight times against twelve for the platform.
   2. Then the synergy. That extra million of EBITDA, capitalised at your platform's exit multiple, is worth ten or twelve million of enterprise value to you.
   3. The negotiation is about how much of that you concede. A disciplined buyer pays little or nothing for synergies it creates; a competitive auction forces you to share some of it.
   4. So I would express it as a range: I would open at the standalone multiple, and my walk-away is the price at which the deal stops clearing my return hurdle after synergies.
   5. Then check the maths on the multiple arbitrage: buying at seven times and having it valued at twelve inside the platform creates value immediately, and that arbitrage is the core of any buy-and-build.
   6. And I would probability-weight the synergy. Cost synergies in a bolt-on are largely deliverable; revenue synergies rarely are, so I would underwrite only the former.

   Where candidates lose it

   Adding the synergy to the target's EBITDA and paying a full multiple on the combined figure. That hands the entire value creation to the seller before you have done any work, and it is the error the question is designed to find.

   Expect next

   • How much of the synergy would you pay away in a competitive auction?
   • What is multiple arbitrage?
   • How do you underwrite synergies in diligence?

7. 012Which of our portfolio companies would you not have bought, if you had been the decision maker at the time?Firm knowledgeHardsuperdayEQTLeveraged Buyouts · Germany · 2018Bessemer Venture PartnersGrowth Equity · New York · 2014

   Say this

   Pick a real deal, give a specific analytical reason, and frame it as a judgement made with the information available at the time rather than with hindsight. Then say what would have changed your mind.

   Then walk it

   1. Do the homework. You need to know their portfolio well enough to name three or four deals and something about each. Turning up unable to name any is the actual failure mode here.
   2. Pick one with a defensible objection: a cyclical bought near the peak, a platform in a sector facing structural substitution, a deal where the entry multiple looks high against the peer set.
   3. Give the reason in investment terms, not moral ones: 'the entry multiple implied mid-cycle margins persisting, and the sector's capacity additions made that hard to underwrite'.
   4. Be respectful and genuinely uncertain: they made the decision with diligence you have not seen, and saying so is not weakness, it is accuracy.
   5. Then the constructive turn: what would you have needed to see to get comfortable? That converts criticism into the kind of reasoning they do in an investment committee.
   6. And have a positive one ready too, because the natural follow-up is which deal you admire and why.

   Where candidates lose it

   Refusing to criticise anything, which reads as either unprepared or unwilling to hold a view. Equally bad is attacking a deal without knowing the facts. Pick one, reason carefully, and concede the information asymmetry.

   Expect next

   • Which one would you have fought hardest for?
   • What is the worst investment this firm has made?
   • What do you know about our fund?

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?
