Private Equity interview preparation
Buyout, growth and credit. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it. Answers lead with the point, then the mechanism, then the limitation.

001Walk me through an LBO.TPGInvestment Banking · New York · 2024Advent InternationalTechnology, Media and Telecom · Palo Alto · 2020Advent InternationalPrivate Equity · New York · 2021Truist SecuritiesGeneralist · Charlotte · 2024
Say this
Buy a business mostly with debt, use its cash flow to pay that debt down, improve the operations, then sell in five years. The equity return comes from deleveraging, EBITDA growth and any change in the exit multiple.
Then walk it
- Entry: agree a purchase price as a multiple of EBITDA, then build sources and uses. Debt goes in as far as the credit market will support, say five times EBITDA, and the sponsor funds the rest plus fees.
- Operating model for five years, then the debt schedule: interest, mandatory amortisation, and a cash sweep applying surplus cash to repay debt.
- Each year free cash flow after interest reduces debt, so the equity slice grows even with a flat enterprise value.
- Exit at an assumed multiple on final-year EBITDA, subtract remaining debt, and that is exit equity.
- Compute IRR and money multiple, then attribute the return across the three drivers. An investment committee will always ask which one carries the deal.
- The discipline point: if the return only works on multiple expansion, it is not a thesis, it is a market bet. I would want it to clear on deleveraging and EBITDA alone.
Where candidates lose it
Describing the mechanics without attributing the return. Every serious LBO answer ends with which of the three drivers produces the IRR and an acknowledgement that multiple expansion is the one you do not control.
Expect next
- How does private equity create value?
- Do a paper LBO for me.
- What makes a good LBO candidate?

022What diligence workstreams would you run, and which one would you prioritise?Advent 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
- 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.
- Financial and quality of earnings: normalising EBITDA, working capital, and the reliability of the forecast.
- Legal: contracts, change of control provisions, litigation, employment, and ownership of intellectual property.
- Tax and structuring: the acquisition structure, historic exposures, and how the exit will be taxed.
- 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.
- 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?

023What would make you walk away from a deal in diligence?Advent 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
- 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.
- Earnings that are not real: quality of earnings revealing that adjusted EBITDA is materially overstated, or revenue recognition that pulls forward future periods.
- 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.
- Structural market deterioration discovered in commercial diligence: substitution, a regulatory change, a competitor's product that changes the economics.
- 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.
- 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?

034Why private equity rather than banking or a hedge fund?Carlyle GroupLeveraged Buyouts · New York · 2022Advent InternationalPrivate Equity · New York · 2021Insight PartnersGeneralist · New York · 2024
Say this
Because of ownership. In banking you advise and hand the deal over; in private equity you live with the consequences for five years. That accountability, and the operating involvement that comes with it, is the difference.
Then walk it
- Name what banking gave you and what it did not: execution skill, financial fluency, exposure to many situations, but no say in whether the deal was a good idea and no involvement after closing.
- The private equity distinction is owning the outcome. You choose, you build the plan, you sit on the board, and in five years the result is attributable to your judgement.
- Against a hedge fund: the horizon and the nature of influence. A public market investor forms a view and waits; a sponsor can change the business. If you want to affect the outcome rather than predict it, that is the honest reason.
- Be specific about what attracted you, ideally from a real deal you worked on. 'I worked on a carve-out and spent most of my time on the separation plan, and that was the part I found most interesting' is far better than an abstract preference.
- Acknowledge what you give up: fewer transactions, a slower feedback loop, and long periods of diligence that leads nowhere.
- Then connect it to their specific model, because the answer should differ between a large-cap financial engineering shop and an operationally intensive mid-market fund.
Where candidates lose it
Saying private equity is 'more interesting' or 'better hours'. Neither is compelling and the second is not true. The credible reason is ownership and accountability, evidenced from something you actually experienced.
Expect next
- What did you like least about banking?
- Why our fund rather than a larger one?
- What would you find hardest about this job?

093How many books were sold in the US last year?Advent InternationalPrivate Equity · Boston · 2022
Say this
Around 700 million to 1 billion units. Take 330 million people, assume about half buy any books, and an average of four to six a year among buyers.
Then walk it
- Population 330 million, less young children, so about 280 million potential buyers.
- Participation: perhaps half buy at least one book in a year, so 140 million buyers. Flag this as the least certain assumption.
- Intensity: the distribution is heavily skewed, with most buyers taking two or three and a small group of heavy readers taking twenty or more. An average of five across buyers is reasonable.
- 140 million times 5 gives 700 million units.
- Then the segments not in that figure: institutional and textbook purchases driven by schools rather than individuals, which might add 50 to 100 million.
- So 750 million to 1 billion. Published US print unit figures sit around 750 million, so the estimate holds, and I would name participation rate and books per reader as the two assumptions the answer is most sensitive to.
Where candidates lose it
Using a flat population-wide average and ignoring the skew. Also failing to say which assumption drives the answer, which is the part that makes it a market-sizing answer rather than a guess.
Expect next
- Now size it in dollars.
- Which assumption would you check first?
- How would you size a market bottom-up for a diligence?

098What do you think you would find hardest about this job?Advent InternationalBusiness Services · London · 2023Millennium ManagementTechnology · London · 2024
Say this
Name something real and specific to the job, then say what you are doing about it. A non-answer here reads as either no self-awareness or no understanding of the role.
Then walk it
- Good candidates: the low hit rate and months of work ending in no deal; the shift from executing a defined task to forming an independent view with incomplete information; the slower feedback loop compared with banking.
- Or something genuinely personal: less structure and less direction than a banking analyst programme, or having to challenge senior people in an investment committee early in your tenure.
- Be specific about why it is hard for you, with an example. 'Coming from banking I was rewarded for executing what I was told, and I noticed on my last deal that I had no view of my own on the price' is honest and shows reflection.
- Then the mitigation, concretely: what you have already started doing about it.
- Avoid the fake weakness. 'I work too hard' and 'I am a perfectionist' are recognised instantly and cost you credibility for the rest of the interview.
- And avoid naming something disqualifying: the hours, the pressure, or working with numbers. Those are the job.
Where candidates lose it
A disguised strength. Interviewers hear it constantly and it signals you are managing them rather than answering. Pick something genuinely difficult that is not fatal to the role, and show you have thought about how to handle it.
Expect next
- What are you doing about it?
- What did you like least about your last role?
- How do you handle being told you are wrong?
