1. 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?

2. 096What is a management presentation and how should a sponsor read it?Due diligenceIntermediatetechnicalM&A

   Say this

   It is the seller's pitch, delivered by the management team, and it is coached. Read it for what is emphasised, what is absent, and how management responds when you push off-script.

   Then walk it

   1. Structure: management walks through the business, the market, the financial history and the forward plan, usually with the sell-side adviser in the room and a prepared deck.
   2. It is a sales document. The bankers have rehearsed it, the forecast is the optimistic case, and the risks section is minimal. Treat every number as a claim requiring verification.
   3. What to look for: which metrics they choose to present, and which standard sector metrics are conspicuously absent. Missing disclosure is usually deliberate.
   4. How the team performs matters as much as the content. Who answers which questions tells you where the real capability sits. A CEO who cannot answer an operational question without turning to a colleague is telling you something.
   5. The highest-value part is going off-script: ask about the worst customer, the biggest operational failure last year, what they would do differently. The prepared answers stop and you learn how they think.
   6. Then reconcile it against the data room and the quality of earnings work afterwards. The gap between the presentation's forecast and your own rebuilt forecast is the single most useful output of the whole exercise.

   Where candidates lose it

   Treating the forecast as a base case. It is the seller's best case, and the professional response is to rebuild the forecast independently and present the gap. Also missing that observing the team is half the purpose.

   Expect next

   • What would you ask off-script?
   • How would you rebuild their forecast?
   • What does it mean if management cannot answer an operational question?
3. 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?

4. 099Why did you leave, or why are you leaving, your current firm?Career and fitIntermediatefirst roundEQTInfrastructure · Munich · 2013Moody'sAnalytics · New York · 2018Millennium ManagementTechnology · London · 2024

   Say this

   Move toward something rather than away from something. Name what this role offers that your current one structurally cannot, and keep any criticism of your current employer minimal and factual.

   Then walk it

   1. Frame it as a pull, not a push. 'I want ownership of the investment decision and the outcome, which an advisory seat structurally cannot give me' is a reason that survives scrutiny.
   2. Be specific about what is structurally unavailable where you are, because 'structural' is what makes it credible. A complaint about a bad staffer sounds like a problem you carry with you; a point about the nature of the seat does not.
   3. Never disparage your current firm, your team or your clients. Interviewers assume you will one day talk about them the same way.
   4. If you are leaving after a short tenure, address it directly rather than hoping they will not ask. The EQT and Moody's versions of this question specifically probe early departures.
   5. If there was a genuine problem, a restructuring, a team that dissolved, a group being wound down, state it plainly and factually. Concrete circumstances are easy to verify and easy to accept.
   6. Close on the forward-looking reason and tie it to this specific firm, so the answer doubles as a 'why us'.

   Where candidates lose it

   Criticising your employer, however justified. It is the most reliable way to lose an interview you were winning. And being evasive about a short tenure, which invites more suspicion than the honest explanation would.

   Expect next

   • Why are you looking to switch after only six months?
   • What did you like least about it?
   • What would make you stay somewhere for ten years?
