1. 022What diligence workstreams would you run, and which one would you prioritise?Due diligenceIntermediatetechnicalAdvent 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

   1. 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.
   2. Financial and quality of earnings: normalising EBITDA, working capital, and the reliability of the forecast.
   3. Legal: contracts, change of control provisions, litigation, employment, and ownership of intellectual property.
   4. Tax and structuring: the acquisition structure, historic exposures, and how the exit will be taxed.
   5. 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.
   6. 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?

2. 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?

3. 093How many books were sold in the US last year?BrainteasersIntermediatetechnicalAdvent 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

   1. Population 330 million, less young children, so about 280 million potential buyers.
   2. Participation: perhaps half buy at least one book in a year, so 140 million buyers. Flag this as the least certain assumption.
   3. 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.
   4. 140 million times 5 gives 700 million units.
   5. Then the segments not in that figure: institutional and textbook purchases driven by schools rather than individuals, which might add 50 to 100 million.
   6. 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?

4. 098What do you think you would find hardest about this job?Career and fitIntermediatesuperdayAdvent 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

   1. 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.
   2. 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.
   3. 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.
   4. Then the mitigation, concretely: what you have already started doing about it.
   5. 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.
   6. 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?
