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. 019What would you do in the first hundred days after closing?OperationsIntermediatesuperdayVista Equity PartnersPrivate Equity · Austin · 2023

   Say this

   Get visibility, get the team right, and start the two or three initiatives that carry the value creation plan. Reporting first, because you cannot manage what you cannot see.

   Then walk it

   1. Reporting and data: install a monthly reporting pack with the KPIs that matter, not just statutory accounts. Founder-run businesses often lack unit-level profitability, customer cohort data or a proper pipeline view, and that is the first thing to fix.
   2. Cash: a thirteen-week cash flow forecast, working capital discipline, and confirmation that covenant headroom is where diligence said it was.
   3. People: assess the leadership team honestly against the plan. The single most common source of underperformance is keeping the wrong CFO too long, and the decision gets harder every month you delay.
   4. Pick two or three initiatives, not ten. Pricing is usually the fastest payback and requires no capital. Then whichever of cost, commercial or bolt-on pipeline the thesis rests on.
   5. Set the governance: board cadence, the operating partner's role, and clear accountability for each initiative with a named owner and a date.
   6. And the cultural point: the first hundred days set the tone. Being clear about what is changing and what is not reduces the attrition risk that follows every change of ownership.

   Where candidates lose it

   Producing a generic consulting list. The private-equity-specific content is reporting infrastructure first, an honest management assessment early, and ruthless prioritisation to two or three initiatives.

   Expect next

   • How would you assess the management team?
   • What if the CFO is not good enough?
   • Which initiative gives the fastest payback?

5. 020How would you evaluate a deal? Walk me through your process.Investment judgementIntermediatetechnicalApollo Global ManagementReal Estate · New York · 2026TPTPGInvestment Banking · San Francisco · 2019

   Say this

   Market, then company, then plan, then price, then structure, then exit. Decide whether it is a business you want to own before you decide what it is worth.

   Then walk it

   1. Market: is it growing, is it fragmented, what drives demand, and is the structure stable? A good company in a deteriorating market is a hard hold.
   2. Company: market position, customer concentration, revenue quality and recurrence, margin durability, and the real earnings power after quality-of-earnings adjustments.
   3. The plan: what do we do that the current owner is not doing? If there is no specific answer, you are paying full price for someone else's work.
   4. Price and returns: what multiple, what leverage, what IRR under base and downside cases. Crucially, what must be true for the base case to hold.
   5. Structure and risk: covenant headroom in a downside, customer or supplier concentration, key-person risk, litigation, regulatory exposure.
   6. Exit: who buys it and at what multiple, and does the deal still work if the exit multiple is a turn below entry. That last sensitivity is the one investment committees always run.

   Where candidates lose it

   Leading with the model. Sponsors want to hear judgement about the business first and arithmetic second. And every answer should include what must be true, because that framing is how investment committees actually discuss deals.

   Expect next

   • What must be true for this to work?
   • What would make you walk away?
   • What if you exit a turn lower than entry?

6. 022What diligence workstreams would you run, and which one would you prioritise?Due diligenceIntermediatetechnicalAdvent InternationalPrivate Equity · Boston · 2022

   Say this

   Commercial, financial, legal, tax, and then the specialist streams the thesis demands. I would prioritise whichever workstream tests the single assumption the return depends on.

   Then walk it

   1. Commercial due diligence: market size and growth, competitive position, customer interviews and win-loss analysis. This is the one that most often changes the price or kills the deal.
   2. Financial and quality of earnings: normalising EBITDA, working capital, and the reliability of the forecast.
   3. Legal: contracts, change of control provisions, litigation, employment, and ownership of intellectual property.
   4. Tax and structuring: the acquisition structure, historic exposures, and how the exit will be taxed.
   5. Then the thesis-specific streams: technology and code review for a software asset, environmental for an industrial site, regulatory for healthcare, IT and cyber for anything data-heavy, insurance and pensions where relevant.
   6. Prioritisation is the actual answer: identify the one assumption that carries the return, then spend the budget there. If the case rests on retaining the top ten customers, customer reference calls matter more than a perfect tax structuring memo.

   Where candidates lose it

   Listing workstreams without prioritising. Diligence budgets and timelines are finite, and the judgement being tested is whether you can identify the assumption that carries the return and aim the work at it.

   Expect next

   • What would you ask in a customer reference call?
   • What finding would kill the deal?
   • How do you diligence a founder-run business?

7. 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?

8. 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?

9. 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?

10. 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?
