1. 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?

2. 035Walk me through a transaction you worked on and what your specific role was.Career and fitIntermediateevery roundCarlyle GroupAsset Management · Washington · 2015Vista Equity PartnersHealthcare · Austin · 2023WBWilliam BlairInvestment Banking · Atlanta · 2026TPTPGInvestment Management · Hong Kong · 2019

   Say this

   Set the deal up in thirty seconds, then spend the time on your own analysis and your own view. They are testing whether you thought about the business or just built the model you were told to build.

   Then walk it

   1. Open with the facts: what the business does, the size, the parties, the multiple and the structure. Be precise, because vagueness suggests you were peripheral.
   2. Then your actual role, honestly. Overclaiming is transparent and the follow-up questions will expose it. 'I built the operating model and ran the diligence question log' is credible and enough.
   3. Then the analysis you personally did, in detail. The one piece of work you can go deepest on is where the interview will go, so choose the deal where you have that depth.
   4. Then your own view: would you have done the deal at that price? This is the part that separates candidates. Bankers who have no opinion on their own transactions struggle in sponsor interviews.
   5. Then what you learned and what you would have pushed on differently, which shows reflection rather than recitation.
   6. Know the numbers cold: entry multiple, leverage, growth rate, margin, and roughly what the returns would look like. Expect to be asked to compute the IRR on the spot.

   Where candidates lose it

   Describing the process rather than the business, and having no view on whether the deal was good. Sponsors ask this to find out whether you think like an investor or like a service provider.

   Expect next

   • Would you have done the deal?
   • What were the transaction multiples?
   • What was the buyer universe and who else looked at it?

3. 037If a company raises $100 of debt to buy back $100 of shares, what happens to enterprise value and equity value?ValuationIntermediatetechnicalSilver LakeTechnology, Media and Telecom · San Francisco · 2022

   Say this

   Enterprise value is unchanged, because the operating business did not change. Equity value falls by $100 and net debt rises by $100, so the two offset exactly.

   Then walk it

   1. Enterprise value is the value of the operating assets. Issuing debt and retiring stock rearranges the claims on those assets without touching them.
   2. Equity value falls by the $100 spent on the buyback. Net debt rises by the $100 raised. EV equals equity plus net debt, so it is unchanged.
   3. Share count falls, so value per share need not fall. If the buyback was executed at fair value, per-share value is unchanged; above fair value it destroys per-share value, below it creates it.
   4. The second-order effects are where it gets interesting: the tax shield on the new debt adds some value, while higher leverage increases distress risk and the cost of equity. In the Modigliani-Miller frame with taxes, the tax shield dominates at moderate leverage.
   5. EPS usually rises because the share count fell more than net income did, but as always that is arithmetic rather than value creation.
   6. So the clean answer: EV flat, equity down $100, net debt up $100, per-share value depends entirely on the price paid.

   Where candidates lose it

   Saying enterprise value falls because debt went up. Debt is part of the bridge, not part of enterprise value. This is the single most common enterprise value misunderstanding and it gets tested constantly.

   Expect next

   • What happens to value per share?
   • When is the buyback value-destructive?
   • What happens to WACC?

4. 039If revenues get hit in a quarter, what would you do as the CFO to preserve cash?OperationsIntermediatetechnicalSilver LakeTechnology, Media and Telecom · San Francisco · 2022

   Say this

   Work from fastest and most reversible to slowest and most damaging. Working capital first, then discretionary spend, then capital expenditure, then headcount, and only then the financing options.

   Then walk it

   1. Working capital gives you cash within weeks and costs nothing structural: chase receivables, tighten credit terms, slow payables within contractual limits, and run down inventory.
   2. Discretionary opex next: travel, marketing programmes, consultants, contractors, non-essential projects. Fast, reversible, and largely invisible to customers.
   3. Capital expenditure: defer growth CapEx immediately, protect maintenance CapEx, because deferred maintenance is borrowing from next year at a bad rate.
   4. Headcount last among operational levers, because it is slow to take effect, carries severance cost upfront, and is expensive to reverse. Hiring freezes before redundancies.
   5. Financing in parallel: draw the revolver before conditions deteriorate, talk to lenders early about covenant headroom, and consider a sponsor equity injection if the shortfall is temporary.
   6. And the governance point: build a thirteen-week cash flow forecast immediately, update it weekly, and tell the lenders before they find out from the quarterly reporting. A surprised lender is a hostile lender.

   Where candidates lose it

   Going straight to headcount. It is slow, costly upfront and destroys capability. Working capital is faster and reversible, and knowing the sequence is the whole answer. Also, forgetting to communicate with lenders early.

   Expect next

   • What if it turns out to be structural rather than temporary?
   • When would you draw the revolver?
   • How do you know whether to cut or invest through it?

5. 040What metrics would you look at when valuing a retail company?Sector knowledgeIntermediatetechnicalSilver LakeTechnology, Media and Telecom · San Francisco · 2022

   Say this

   Same-store sales decomposed into traffic and ticket, gross margin, sales per square foot, inventory turns, and the four-wall economics of a store. Then lease liabilities, because that is where retail leverage hides.

   Then walk it

   1. Comparable store sales is the quality signal, because total revenue growth can be manufactured by opening stores. Break it into transactions and average ticket, and ticket into units and price.
   2. Gross margin trend against comps tells you whether sales are being bought with discounting.
   3. Sales per square foot and four-wall EBITDA, meaning store-level profit before corporate overhead. That determines whether new stores create value and what the payback period on a new store is.
   4. Inventory turns and the inventory-to-sales relationship. Inventory building faster than sales is the earliest reliable warning of markdowns to come.
   5. Online mix and its profitability, including returns and delivery cost, because e-commerce margin is often far worse than the store channel once fulfilment is loaded.
   6. For a sponsor specifically: the lease portfolio. Rent is a fixed obligation and the lease liability behaves like debt, so a retailer with a long lease estate is far more levered than its net debt suggests. And the real estate itself may be worth more than the operating business, which changes the whole thesis.

   Where candidates lose it

   Giving generic metrics with no retail specificity. Four-wall economics, inventory turns and the lease liability are the three that mark out someone who has looked at a retail deal.

   Expect next

   • How do you treat lease liabilities in leverage?
   • What is four-wall EBITDA?
   • Would you rather own the real estate or the operating company?

6. 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?

7. 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?
8. 047How would you assess the management team?Due diligenceIntermediatetechnicalVista Equity PartnersHealthcare · Austin · 2023

   Say this

   Against the plan, not in the abstract. The question is not whether they are good managers but whether this team can execute this specific value creation plan over the next five years.

   Then walk it

   1. Start from the plan and work backwards: if the thesis is a pricing transformation and a buy-and-build, you need a commercial leader who has taken price and a CFO who has integrated acquisitions. Match capability to the specific job.
   2. Track record over assertions: what did each person actually deliver in previous roles, with numbers, and verified through references rather than their own account.
   3. Reference calls are the highest-value tool, and off-list references are worth more than the ones provided. Former colleagues, former bosses, and people who worked for them.
   4. Test their own diagnosis. Ask what they would do with more capital and fewer constraints. A management team with no clear answer has not been thinking like owners, which is both a risk and an opportunity.
   5. Assess the gaps honestly and budget for them. It is normal to replace one or two of a founder-led team, and pretending otherwise just delays it.
   6. And test cultural fit with sponsor ownership specifically: monthly reporting, board scrutiny, a five-year clock. Some excellent managers genuinely do not want that, and finding out after closing is expensive.

   Where candidates lose it

   Assessing charisma from meetings. Management teams in a sale process are coached and selected for presenting well. Reference calls and delivered track record are the evidence; the interview is not.

   Expect next

   • What if the CFO is not strong enough?
   • How quickly would you make a change?
   • How do you keep them motivated through a five-year hold?

9. 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?
10. 051How would you evaluate a real estate investment?Sector knowledgeIntermediatetechnicalApollo Global ManagementReal Estate · New York · 2026BlackstoneReal Estate · Vancouver · 2025InvescoReal Estate · New York · 2025

    Say this

    Net operating income and the cap rate set the value. Then the leases behind that NOI, the debt on the asset, and the exit assumption. The building matters less than the contracts attached to it.

    Then walk it

    1. NOI first: contracted rent, less vacancy and credit loss, less operating expenses not recovered from tenants. That is the income the asset actually produces.
    2. Value equals NOI divided by the cap rate. So the whole valuation question reduces to how durable that NOI is and what cap rate the market applies to that durability.
    3. Lease analysis: weighted average lease term, tenant credit quality, rent against market, escalation clauses, and break options. Long leases to strong covenants justify a lower cap rate.
    4. Capital: what does it cost to maintain, what is the deferred CapEx, and what leasing costs and incentives will you incur to re-let space?
    5. Financing: loan-to-value, the interest rate and whether it is fixed, the debt service coverage ratio, and whether any in-place debt is assumable. Cheap assumable debt is a real asset.
    6. Then returns: unlevered and levered IRR, equity multiple, and cash-on-cash yield. And the exit cap rate assumption, which should be at or above entry, because underwriting cap rate compression is underwriting the market rather than the asset.

    Where candidates lose it

    Underwriting exit cap rate compression. It is the real estate equivalent of assuming multiple expansion and investment committees reject it. Assume the exit cap is equal to or wider than entry and make the deal work anyway.

    Expect next

    • Walk me through getting exit value from gross potential rent using a cap rate.
    • What is the cash-on-cash return at a given LTV?
    • How does a rate move affect both NOI and the cap rate?
