1. 017Walk me through the promote structure on a deal you worked on.Fund economicsHardtechnicalHIH.I.G. CapitalLeveraged Buyouts · New York · 2021

   Say this

   A promote is the sponsor's disproportionate share of profits above a return hurdle. Describe the waterfall: return of capital, then the preferred return, then a catch-up, then a split that steps up at higher return tiers.

   Then walk it

   1. Tier one: return of capital. All investors get their contributed capital back before any profit is shared.
   2. Tier two: the preferred return, typically 8 percent, paid to all capital pro rata.
   3. Tier three: the catch-up, where the sponsor receives most or all of the distributions until it has reached its target share of profits.
   4. Tier four onwards: the split, commonly 80/20, often stepping up to 70/30 or 60/40 above higher IRR hurdles such as 15 or 20 percent. That step-up is what makes the promote asymmetric and is the whole incentive design.
   5. Then the mechanics that matter in practice: whether the hurdle is measured on IRR or on a money multiple, whether it is calculated deal-by-deal or across the whole fund, and whether there is a clawback.
   6. If you have actually worked on a deal, walk through the real numbers and say what the sponsor earned at each tier. If you have not, say so and walk through a standard structure rather than inventing specifics you cannot defend.

   Where candidates lose it

   Not being able to name the tiers in order. If you claim deal experience, expect to be asked for the actual hurdle and split. Never invent specifics about a real deal; being caught fabricating ends the process.

   Expect next

   • IRR hurdle or multiple hurdle, and why does it matter?
   • What is a clawback?
   • How does the management incentive plan interact with this?

2. 018How does the management incentive plan work, and how does it affect your returns?Fund economicsHardtechnicalCitiMergers and Acquisitions · New York · 2026

   Say this

   A pool of equity, typically 8 to 15 percent, granted to management and vesting on time and on returns. It dilutes the sponsor's exit proceeds, so it reduces your IRR but does not change the entry price.

   Then walk it

   1. Structure: a mix of time-vesting equity and performance-vesting equity tied to the sponsor achieving a money multiple or IRR hurdle. The performance tranche is what does the aligning.
   2. Sizing: commonly 8 to 15 percent of fully diluted equity, larger in smaller deals and where management is expected to drive the whole value creation plan.
   3. In the model it sits at exit, reducing the sponsor's share of equity proceeds. So it lowers your IRR rather than raising the purchase price, and modelling it as an entry cost is the common error.
   4. It is distinct from rollover, which is management reinvesting existing proceeds and therefore a source of funds in sources and uses. Rollover aligns on the downside; the incentive plan aligns on the upside.
   5. Design questions that matter: what happens on a good leaver or bad leaver departure, whether there is acceleration on a change of control, and whether the hurdle is set high enough to be motivating but low enough to be believable.
   6. The failure mode to avoid: a plan that goes underwater early in the hold. Once management believes the hurdle is unreachable, the alignment inverts and you have to reprice it, which is expensive and awkward.

   Where candidates lose it

   Confusing it with rollover, or placing it in sources and uses. The incentive pool dilutes exit proceeds; rollover funds the purchase. That distinction is the technical core of the question.

   Expect next

   • How much rollover would you expect from management?
   • What happens if the plan goes underwater?
   • How would you set the hurdle?

3. 021What is a quality of earnings analysis and what are you looking for?Due diligenceHardtechnicalHWHarris WilliamsInvestment Banking · Richmond · 2025

   Say this

   It bridges reported EBITDA to a sustainable, normalised EBITDA that a buyer can actually underwrite. You are looking for anything in the reported number that will not be there next year.

   Then walk it

   1. Add-backs the seller proposes: one-time legal costs, owner's excess compensation, discontinued product lines, pro forma savings from actions already taken. Some are legitimate; many are not.
   2. The ones to challenge hardest: pro forma synergies from actions not yet taken, run-rate adjustments annualising a single good month, and recurring restructuring dressed as one-off.
   3. Revenue quality: customer concentration, contract terms and renewal rates, cut-off testing around the period end, and whether any revenue was pulled forward to flatter the sale process.
   4. Cost completeness: costs the business has not been bearing, such as an owner working unpaid, rent below market on a related-party property, or under-investment in maintenance and IT that a buyer will have to fund.
   5. Working capital: establish a normalised level, because the purchase agreement will have a working capital peg. Sellers manage working capital down before a sale, and if you set the peg from the manipulated level you overpay at completion.
   6. The output is an adjusted EBITDA and a defensible working capital target, and those two numbers are what the price is actually built on.

   Where candidates lose it

   Treating it as an audit. It is not; it is a normalisation exercise. And missing the working capital peg, which is where real money changes hands at completion and which most candidates never mention.

   Expect next

   • What is a working capital peg?
   • Which add-backs would you refuse?
   • How would you verify the pipeline to forecast revenue?

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. 029What is the difference between incurrence and maintenance covenants?Credit and financingHardtechnicalLazardGeneralist · Amsterdam · 2025

   Say this

   A maintenance covenant is tested every quarter regardless of what the borrower does. An incurrence covenant only bites when the borrower takes a specific action, such as raising more debt or paying a dividend.

   Then walk it

   1. Maintenance: the borrower must keep leverage below a level, or coverage above one, tested quarterly. Miss it and you are in default even if nothing else has changed. This is traditional bank loan territory.
   2. Incurrence: the test applies only when you do something, like incur additional debt, make a restricted payment or complete an acquisition. If you sit still and deteriorate, nothing happens. This is bond and covenant-lite territory.
   3. Why sponsors want incurrence: it removes the risk of a technical default during a temporary downturn, which preserves control of the situation.
   4. Why lenders want maintenance: it gives them an early seat at the table when performance deteriorates, while there is still enterprise value to negotiate over.
   5. The market has moved decisively toward covenant-lite structures in broadly syndicated loans, often with only a springing leverage covenant on the revolver tested when it is substantially drawn.
   6. The consequence worth naming: with fewer maintenance tests, lenders find out later and recoveries in default have been lower. That is one of the live concerns about the current credit cycle.

   Where candidates lose it

   Getting them the wrong way round, or not knowing the term covenant-lite. Since covenant-lite is now the market standard in large-cap leveraged finance, not knowing it signals you have not looked at real deal documents.

   Expect next

   • What is a springing covenant?
   • What does covenant-lite mean for recoveries?
   • How much headroom would you negotiate?

10. 030How would you think about a dividend recapitalisation?Fund economicsHardtechnicalRothschild & CoInvestment Banking · London · 2026

    Say this

    Refinance the company to pull cash out to the sponsor without selling. It resets the IRR clock by returning capital early, but it re-levers the business and makes it more fragile.

    Then walk it

    1. Preconditions: the company must have deleveraged enough that re-levering to roughly the original multiple is fundable, and the cash flow must be stable enough that lenders will support it.
    2. The motivation is nearly always sponsor-side: fund life is advancing, the exit window is unattractive, and returning capital early de-risks the deal and flatters the IRR because early cash flows are weighted heavily.
    3. It changes the return profile: money multiple is barely affected, IRR improves materially. That divergence is exactly why limited partners scrutinise recaps.
    4. The downside: leverage is back up, the equity cushion is thinner, and covenant headroom shrinks. If the cycle turns, the business is in trouble and the sponsor has already taken its money off the table.
    5. Lenders price this. A recap financing usually carries a wider spread and tighter terms than the original, reflecting the reduced equity commitment.
    6. The honest assessment: it is a legitimate tool for a genuinely stable asset with excess debt capacity, and it is also how sponsors have historically extracted returns from deals that were not performing well enough to sell.

    Where candidates lose it

    Describing it as free money for the sponsor without the fragility point. Also missing that it inflates IRR while leaving multiple on invested capital unchanged, which is the distinction limited partners actually focus on.

    Expect next

    • How does it affect IRR versus money multiple?
    • Why would lenders agree?
    • What would a limited partner think about it?
