1. 041If margin goes down by 5 percent, how much would you need to increase revenue to hold profit flat?Investment judgementIntermediatetechnicalSycamore PartnersConsumer and Retail · New York · 2026

   Say this

   It depends on whether the 5 percent is relative or absolute, so I would clarify first. If margin falls from 20 percent to 15 percent, an absolute 5 point drop, you need revenue to rise by a third to hold profit flat.

   Then walk it

   1. Take revenue of 100 and a 20 percent margin, so profit is 20.
   2. If margin falls 5 percentage points to 15 percent, you need revenue R where 0.15R equals 20, so R is 133. That is a 33 percent increase.
   3. If the 5 percent is relative, so margin goes from 20 percent to 19 percent, you need 0.19R equals 20, so R is 105. About a 5 percent increase.
   4. The general rule for the relative case: a relative margin decline of x percent requires roughly x percent more revenue, since profit is margin times revenue.
   5. The absolute case is far more punishing, and the lower the starting margin the worse it gets. At a 5 percent starting margin, losing 2 points means you need to grow revenue by two thirds.
   6. The commercial insight: this is why low-margin businesses cannot discount their way out of trouble. Volume almost never compensates for the price given up, which is the maths behind resisting a price war.

   Where candidates lose it

   Not clarifying absolute versus relative. The two answers differ by a factor of six and the interviewer is watching whether you ask. Then do the arithmetic with round numbers out loud.

   Expect next

   • What if the starting margin were 5 percent?
   • So would you ever discount to defend share?
   • How does operating leverage change your answer?

2. 044Why is EBITDA a poor proxy for cash flow, and what would you use instead?AccountingIntermediatetechnicalPrivate creditLeveraged finance

   Say this

   Because it ignores the three things that actually consume cash: capital expenditure, working capital and taxes, plus interest itself. A business can grow EBITDA every year and never generate a dollar of free cash.

   Then walk it

   1. CapEx is the biggest omission. EBITDA adds back depreciation, which is a proxy for the capital the business must eventually respend. For a capital-intensive business, maintenance CapEx alone can absorb most of EBITDA.
   2. Working capital: a growing business funds receivables and inventory, so cash lags EBITDA persistently.
   3. Cash taxes are real, and they differ from book taxes because of timing differences and loss carryforwards.
   4. Interest and mandatory amortisation come before anything reaches the equity, which is precisely what matters when the business is levered.
   5. And adjusted EBITDA compounds the problem, because the adjustments are the company's own judgement. Recurring restructuring charges and run-rate synergies routinely inflate it.
   6. What I would use: unlevered free cash flow for valuation, and for credit, EBITDA less maintenance CapEx less cash taxes less working capital change, compared against debt service. That is the number that tells you whether the structure survives.

   Where candidates lose it

   Reciting the Buffett line about EBITDA without the specific omissions. Name CapEx, working capital and cash taxes explicitly, and name adjusted EBITDA as a separate problem of judgement rather than of definition.

   Expect next

   • How do you split maintenance from growth CapEx?
   • Which add-backs would you refuse?
   • What coverage ratio would you actually underwrite to?
3. 048What is an earnout and when would you use one?Deal structuringIntermediatetechnicalMiddle-market private equityM&A

   Say this

   Deferred consideration contingent on the business hitting agreed targets. You use it to bridge a valuation gap when the buyer does not believe the seller's forecast and the seller will not accept a lower price.

   Then walk it

   1. The mechanism: part of the price is paid at closing and the rest depends on performance over one to three years, usually against revenue or EBITDA targets.
   2. It resolves genuine disagreement. The seller says growth will continue; the buyer is sceptical. An earnout lets each be paid according to what actually happens.
   3. It also retains the seller, which matters most in founder-led and people-dependent businesses where the relationships walk out of the door.
   4. The problems are well known. Revenue-based earnouts incentivise selling at any margin. EBITDA-based earnouts create arguments about cost allocation, because the buyer now controls the accounting. Integration is often delayed to keep the earnout measurable, which destroys value.
   5. So the documentation has to be very precise: exactly how the metric is defined, what the buyer may and may not do during the period, dispute resolution, and treatment on a subsequent sale.
   6. My own view: earnouts solve a negotiation problem and create an operating problem. For a business you intend to integrate immediately, a lower price with no earnout is usually cleaner than a higher price with one.

   Where candidates lose it

   Describing the mechanics without the misalignment problem. The reason experienced buyers dislike earnouts is that they constrain what you can do with the business during the period, and that is the answer worth giving.

   Expect next

   • Revenue or EBITDA based, and why?
   • What if the buyer wants to integrate immediately?
   • How would you handle a dispute?
4. 052Walk me through getting to the exit value of a property from gross potential rent, using a cap rate.Sector knowledgeIntermediatetechnicalInvescoReal Estate · New York · 2025

   Say this

   Start at gross potential rent, subtract vacancy and credit loss to get effective gross income, add other income, subtract operating expenses to get NOI, then divide NOI by the exit cap rate.

   Then walk it

   1. Gross potential rent is what the property would earn fully leased at market rent, so it is a theoretical maximum.
   2. Less vacancy and collection loss, typically 5 to 10 percent depending on the market and asset, gives effective gross income.
   3. Plus other income: parking, storage, laundry, signage, expense recoveries from tenants.
   4. Less operating expenses: property taxes, insurance, utilities, repairs, management fee, and a reserve for replacements. Critically, this excludes debt service and capital expenditure, because NOI is an unlevered, pre-capital measure.
   5. That gives NOI. Divide by the exit cap rate and you have gross exit value. So NOI of $1 million at a 6 percent cap is $16.7 million.
   6. Then subtract selling costs, usually 1 to 3 percent, and repay the outstanding loan balance to get equity proceeds. Those proceeds plus the interim cash flows give you the equity IRR.

   Where candidates lose it

   Including debt service or CapEx in NOI. NOI is deliberately unlevered and pre-capital so that properties with different financing are comparable. Including either makes the cap rate meaningless.

   Expect next

   • What cap rate would you use at exit versus entry?
   • Where do leasing commissions and tenant improvements go?
   • How does a 100 basis point cap rate move change your value?

5. 055How do you source deals, and what makes a good proprietary origination process?Investment judgementIntermediatetechnicalGeneral AtlanticTechnology, Media and Telecom · New York · 2016

   Say this

   Build a thesis first, then map every company in that space, then build relationships with the owners years before they sell. Waiting for banker-run auctions means competing on price alone.

   Then walk it

   1. Thesis-driven mapping: pick a sub-sector, build the full universe of companies in it, rank them on the criteria that matter, and work the list systematically. This is unglamorous and it is what actually produces proprietary deals.
   2. Relationship building over years: the best outcome is being the call a founder makes when they finally decide to sell, before a banker is appointed. That requires having been in touch when you were not buying.
   3. Network channels: operating partners and industry executives, existing portfolio company management, advisers and accountants in the mid-market, and conference presence in a narrow vertical.
   4. Then the honest reality: most deals still come through intermediaries, and the differentiation in an auction is speed, certainty and sector credibility rather than price alone. A sponsor who already owns three companies in the space can move faster and pay with more confidence.
   5. Data and tooling helps at the top of the funnel, screening for company size, growth and ownership signals, but the conversion still comes from relationships.
   6. The measurable version: track how many companies you covered, how many conversations, how many led to a process, and how many closed. Good origination is a pipeline discipline, not luck.

   Where candidates lose it

   Saying you would rely on bankers. Every fund says it wants proprietary deal flow because auctions compete away returns. The credible answer is thesis-led mapping plus long-horizon relationship building, with an honest acknowledgement that most deals are still intermediated.

   Expect next

   • How would you map a sector?
   • What makes you win a competitive auction?
   • What companies interest you right now?

6. 058What is the difference between credit and equity investing?Credit and financingIntermediatefirst roundKKRDistressed Debt · New York · 2025Carlyle GroupCredit · New York · 2022

   Say this

   Credit has a capped upside and a fixed claim, so the job is avoiding losses. Equity has unlimited upside and a residual claim, so the job is finding the outcomes that go right. It changes what you spend your diligence on.

   Then walk it

   1. The payoff shape drives everything. A lender's best case is being repaid in full, so the analysis is entirely about the downside: what happens if this goes wrong and do I still get my money back?
   2. Equity is the opposite. Your downside is fixed at your investment, so the analysis weights the upside scenarios and the size of the opportunity.
   3. Diligence differs accordingly. A credit investor focuses on cash flow stability, asset coverage, covenant protection and the downside case. An equity investor focuses on growth, market position and the value creation plan.
   4. Seniority and control: credit sits ahead in the waterfall and gets contractual protections; equity sits last and gets governance rights. Control in credit is negative, meaning the right to block, while equity control is positive, the right to direct.
   5. Return profile: credit returns are contractual and mostly known at entry, typically high single to low double digits for private credit. Equity returns are uncertain and target 20 percent plus.
   6. And the crossover that makes distressed interesting: in a restructuring the fulcrum creditor converts into the equity, so a credit investor becomes an owner. That is why the two skill sets overlap at the distressed end.

   Where candidates lose it

   Describing seniority only. The examinable insight is that the asymmetric payoff changes what you diligence and how you think, and the distressed crossover is what makes the answer sound like someone who understands both.

   Expect next

   • Which would you rather do and why?
   • How does that change what you look at in diligence?
   • What is the fulcrum security?

7. 062What is a growth equity investment and how does it differ from a buyout?Investment judgementIntermediatefirst roundGeneral AtlanticGrowth Equity · New York · 2022Insight PartnersSoftware · New York · 2022

   Say this

   Growth equity buys a minority stake in a company that is already working and needs capital to scale. Little or no leverage, no control, and the return comes almost entirely from revenue growth rather than from deleveraging.

   Then walk it

   1. Ownership: minority stakes with governance rights negotiated contractually rather than through control. So you influence rather than direct, and the relationship with the founder matters enormously.
   2. Leverage: typically little or none, because the companies are often not profitable enough to service debt. That removes one of the three buyout return drivers entirely.
   3. So the return has to come from growth. If a buyout can make 2.5 times on deleveraging and modest growth, a growth deal needs revenue to compound substantially over the hold.
   4. Risk profile: less risk than venture, because the product works and there is real revenue, but more than a buyout, because you are paying for future growth that may not arrive.
   5. Diligence focus: unit economics, cohort retention, sales efficiency and the scalability of the go-to-market motion, rather than cost structure and cash generation.
   6. And the protections matter more precisely because you lack control: liquidation preference, board seats, information rights, consent rights over major decisions, and drag-along and tag-along provisions on exit.

   Where candidates lose it

   Describing it as a small buyout. The absence of leverage and of control is the defining difference, and it changes both the return maths and the entire diligence focus. Naming the minority protections shows you understand how influence is actually exercised.

   Expect next

   • What protections would you negotiate as a minority investor?
   • How does that change the return maths?
   • Why is it harder to underwrite than a buyout?

8. 064What is the J-curve and why does it matter to a limited partner?Fund economicsIntermediatetechnicalNeuberger BermanPrivate Equity · London · 2022

   Say this

   Early in a fund's life, returns are negative because fees are charged while investments are still held at cost. Value shows up later as assets appreciate and exit, so the return profile traces a J.

   Then walk it

   1. In years one to three the fund calls capital, pays management fees and transaction costs, and holds assets at or near cost. So reported IRR is negative.
   2. From around year four, portfolio companies grow and some are sold, so value marks up and distributions begin. The curve turns upward.
   3. The consequence for a limited partner: judging a fund on its first three years is meaningless, and a young fund's negative IRR says nothing about eventual performance.
   4. It creates a practical allocation problem: an investor building a private equity programme faces years of fees before distributions, so they commit across vintages to smooth the cash flow, and often buy secondaries to get exposure to mature funds that are past the trough.
   5. Managers can flatten the J artificially with subscription lines, delaying capital calls so that the IRR clock starts later. That improves the reported IRR without improving the actual return, which is why sophisticated allocators look at the multiple as well.
   6. It also explains the denominator effect: when public markets fall, private valuations lag, so private equity becomes an outsized share of a portfolio and investors stop committing, which is exactly why fundraising dries up after a public drawdown.

   Where candidates lose it

   Defining the shape without the allocator consequences. The examinable content is vintage diversification, the secondaries solution, and how subscription lines distort the picture.

   Expect next

   • How do subscription lines flatten it?
   • How would a new allocator build a programme around it?
   • What is the denominator effect?

9. 071Walk me through the sources and uses table for a buyout.LBO mechanicsIntermediatetechnicalTSTruist SecuritiesGeneralist · Charlotte · 2024

   Say this

   Uses is everything you have to pay for; sources is where the money comes from. They must equal, and sponsor equity is the plug that makes them balance.

   Then walk it

   1. Uses: the purchase price of the equity, repayment of existing debt if it is not assumed, transaction fees for advisers and lawyers, financing fees, and cash left on the balance sheet to run the business.
   2. Sources: new senior debt, any subordinated or mezzanine tranche, management rollover equity, seller notes if any, cash already on the target's balance sheet, and finally sponsor equity.
   3. Sponsor equity is calculated last as the difference. That is why raising another turn of debt directly reduces the cheque size and mechanically lifts the equity return.
   4. Two things candidates forget: financing fees, which can be two to three percent of the debt raised and are real cash out, and minimum cash to operate, which is a use not a free resource.
   5. Cash on the target's balance sheet is a source, but only the excess above what the business needs to trade. Treating all of it as available is a common error.
   6. The table is also where the structure becomes visible: the mix of senior, mezzanine and equity, and how much management is rolling, are all read off it in one glance, which is why it is the first page of any investment committee memo.

   Where candidates lose it

   Omitting fees and minimum cash. Both are real uses and both make the equity cheque bigger. And treating the entire cash balance as a source when most of it is working capital the business needs to operate.

   Expect next

   • Where does management rollover sit?
   • How much cash would you leave in the business?
   • What happens to the table if you raise another turn of debt?

10. 073What is a cash sweep and how does it work in the debt schedule?LBO mechanicsIntermediatetechnicalLeveraged finance

    Say this

    A contractual requirement to use a percentage of excess free cash flow to repay debt early, on top of mandatory amortisation. In the model it is what drives deleveraging beyond the scheduled repayments.

    Then walk it

    1. Order of operations in the schedule: start with cash available for debt service, pay interest, pay mandatory amortisation, then apply the sweep percentage of whatever remains to prepay the term loan.
    2. The sweep percentage is usually stepped: 75 percent of excess cash flow at high leverage, falling to 50 percent and then to zero as leverage ratios come down. That gives the sponsor cash back as the credit improves.
    3. It applies to the term loan, and prepayments are typically applied to the remaining amortisation schedule, which reduces future mandatory payments as well.
    4. Modelling note: the sweep is circular, because interest depends on the debt balance and the debt balance depends on the cash left after interest. Either iterate or use a simple average balance convention and say which you are doing.
    5. Why lenders want it: it forces deleveraging automatically rather than letting the sponsor accumulate cash or pay it out.
    6. Why sponsors resist it: cash swept is cash not available for bolt-on acquisitions or a dividend. Negotiating the step-downs and the carve-outs for permitted acquisitions is a real part of the financing negotiation.

    Where candidates lose it

    Not knowing that the percentage steps down with leverage, or ignoring the circularity in the model. Both are things you only know from having built a debt schedule rather than read about one.

    Expect next

    • How do you handle the circularity?
    • Why would a sponsor negotiate the sweep down?
    • What is a permitted acquisition basket?
