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. 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?

3. 007What makes a good LBO candidate?Investment judgementCorefirst roundWPWarburg PincusPrivate Equity · San Francisco · 2014Clayton Dubilier and RicePrivate Equity · London · 2026GSGuggenheim SecuritiesHealthcare · London · 2026

   Say this

   Predictable cash flow that can service debt, low capital intensity, a defensible market position, a clear operational improvement to make, and a credible exit. Stability matters more than growth.

   Then walk it

   1. Cash flow stability first, because debt service is non-negotiable. Contracted or recurring revenue, low cyclicality, sticky customers, and a demonstrated ability to hold margin through a downturn.
   2. Low maintenance CapEx, since every dollar spent on the asset base is a dollar not repaying debt.
   3. Defensible position: switching costs, scale, regulation, brand. Something that protects margin for the five years you own it without requiring you to outspend competitors.
   4. An identifiable value creation lever: an underinvested commercial function, a bloated cost base, a fragmented sector supporting a buy-and-build, or a non-core division to divest.
   5. A real exit. A deep strategic buyer list, or a listed peer group at a decent multiple. The best entry price is worthless if nobody will buy it from you in five years.
   6. And the anti-candidate, which is worth naming: high-growth, cash-burning, cyclical, capital-heavy. That can be an excellent investment and a terrible LBO, and knowing the difference is the point of the question.

   Where candidates lose it

   Putting high growth near the top. Growth consumes cash and cash service is the binding constraint. Saying that venture-style growth is the opposite of what an LBO structure wants shows you understand why the structure exists.

   Expect next

   • Pitch me a company that would be a great LBO candidate.
   • Why is high growth not necessarily good?
   • Would you invest in a company with negative sales growth?

4. 077Tell me about a time you disagreed with a superior.Career and fitIntermediatesuperdayHIH.I.G. CapitalLeveraged Buyouts · San Francisco · 2023WPWarburg PincusTechnology Consulting · New York · 2020

   Say this

   Pick a disagreement about substance, show that you raised it directly and with evidence, and be honest about the outcome, including the cases where you were wrong.

   Then walk it

   1. Choose a professional disagreement about analysis or approach, not a personality clash. An analytical disagreement shows judgement; a personal one shows you cannot work with people.
   2. Set it up briefly: what the decision was, what they thought, what you thought and why.
   3. Then the how, which is the part being assessed. You raised it privately, with the analysis to back it up, framed as a question rather than a challenge, and at a point when it could still change the outcome.
   4. Then the outcome, honestly. If you were overruled, say so and say whether you now think they were right. If you turned out to be wrong, that is a stronger answer, not a weaker one.
   5. Then how you behaved afterwards: you committed to the decision once it was made. Investment committees need people who argue hard and then execute the decision.
   6. Avoid stories where you went around your manager, or where you were silently right and everyone later regretted it. Neither reads well.

   Where candidates lose it

   Choosing a disagreement where you were obviously right and they were obviously foolish. It sounds self-serving and interviewers discount it. A case where you argued well and turned out to be wrong is more persuasive evidence of judgement.

   Expect next

   • What if they had overruled you and been wrong?
   • Tell me about a time things did not go your way.
   • How do you argue in an investment committee?

5. 079What are the transaction multiples on the deals on your resume?Career and fitIntermediateevery roundWPWarburg PincusPrivate Equity · New York · 2014Carlyle GroupAsset Management · Washington · 2015Audax GroupLeveraged Buyouts · New York · 2025

   Say this

   Know every number on your resume cold: enterprise value, the entry multiple on both EBITDA and revenue, leverage, the growth rate, the margin, and roughly what returns the structure implied. Not knowing them is disqualifying.

   Then walk it

   1. For each deal listed, be able to state without hesitation: enterprise value, EV/EBITDA, EV/revenue if relevant, leverage as a multiple of EBITDA, and the premium if it was public.
   2. Then the operating numbers: revenue, growth rate, EBITDA margin, and the direction each has been moving.
   3. Then your view: was the multiple justified against the comparable set, and what did the buyer need to believe?
   4. For confidential deals, give the numbers in ranges or as multiples rather than absolute figures if the specifics are not public. Saying 'I can talk about it on a multiples basis because the absolute figures are not public' is the professional answer and interviewers respect it.
   5. Audax explicitly asks candidates to describe something small on their resume, which is the same test in another form: everything on the page is fair game, including the line you thought nobody would ask about.
   6. So the preparation rule is simple: if you cannot discuss a line on your resume for five minutes, take it off the resume.

   Where candidates lose it

   Putting a deal on your resume you cannot discuss in detail. Sponsors interview by going deep on one transaction, and a candidate who worked on the periphery and cannot answer basic questions is immediately exposed.

   Expect next

   • Would you have done the deal?
   • Who else was in the process?
   • Describe something small on your resume.

6. 086What is the difference between IRR and multiple on invested capital, and can they disagree?ReturnsIntermediatetechnicalWPWarburg PincusPrivate Equity · New York · 2012

   Say this

   IRR is a time-weighted annual rate; MOIC is total cash out over cash in with no time dimension. They disagree constantly, because a fast small return can beat a slow large one on IRR while returning far less money.

   Then walk it

   1. A deal returning 1.5 times in one year is a 50 percent IRR but only half your money back in profit. A deal returning 3 times over seven years is about a 17 percent IRR but three times the money.
   2. Limited partners ultimately spend cash, not rates, so MOIC and DPI matter enormously to them. But IRR is the industry's headline, which creates the incentive to shorten holds.
   3. The ways IRR gets flattered: an early dividend recap, a quick partial sale, and subscription lines that delay calling capital so the clock starts later. None of these increase the money returned.
   4. IRR also has technical problems: it assumes reinvestment at the IRR itself, which is usually unrealistic, and it can produce multiple solutions when cash flows change sign more than once.
   5. So the professional practice is to quote both, always, plus DPI to show what has actually been returned in cash.
   6. The practical rule I would give: judge a deal on MOIC for how much value was created, and on IRR for how efficiently the capital was used. Neither alone tells you whether it was a good investment.

   Where candidates lose it

   Treating IRR as the definitive measure. It is the headline but it is gameable through timing, and knowing specifically how it is gamed, recaps and subscription lines, is what distinguishes a real answer.

   Expect next

   • How would you game an IRR?
   • Which would a limited partner prefer?
   • What is DPI and why does it matter?
