1. 021What is the difference between the sell side and the buy side, and why do you want this one?Career and fitCorephone / first roundMan GroupEquity Hedge · Boston · 2019T. Rowe PriceEquity Research · New York · 2026

   Say this

   The sell side publishes research to clients and is paid for the service, so breadth, access and communication matter. The buy side makes decisions with capital at risk, so depth and being right matter. Pick the one whose scoreboard you actually want.

   Then walk it

   1. Sell side: publish notes, maintain models across 10 to 20 names, host management meetings and conferences, talk to clients constantly. You are measured on the quality and usefulness of the service and, increasingly, on client votes.
   2. Buy side: fewer names, far deeper, and the output is a recommendation to a portfolio manager rather than a published note. You are measured on whether the calls made money.
   3. The cultural difference: the sell side rewards visibility and responsiveness; the buy side rewards judgement and conviction, and tolerates being quiet.
   4. Say which you want and why, honestly. 'I want the accountability of a position, so I want the buy side' is a good answer. So is 'I want breadth and access early in my career, which is why I want to start sell side'.
   5. If you are interviewing on the sell side, do not describe it as a stepping stone to the buy side, even though many people treat it that way. They know, and saying it is careless.

   Where candidates lose it

   Describing the sell side as merely a training ground. It is a career in itself and the person interviewing you has chosen it. Be specific about what attracts you to the seat you are actually sitting in.

   Expect next

   • Do you see yourself doing this for the rest of your career?
   • Why this firm rather than a bank?
   • How is sell-side research paid for now?

2. 022Do you see yourself doing this for the rest of your career?Career and fitIntermediatesuperdayMan GroupEquity Hedge · Boston · 2019Fidelity InvestmentsEquity Research · Toronto · 2026

   Say this

   Say yes, and make it credible by describing what specifically about the work would sustain you for twenty years. Research firms hire slowly and expect long tenure, so this question is a genuine screen, not a formality.

   Then walk it

   1. Answer directly. Hedging here reads as someone passing through, and in a small investment team that is expensive.
   2. Then give the reason that survives the glamour wearing off: the work is the same at year one and year twenty, reading filings, building a view, being wrong sometimes, and compounding knowledge of an industry.
   3. Name the specific appeal: the feedback loop. Very few careers tell you clearly whether you were right. For people who want that scoreboard, nothing else substitutes.
   4. Acknowledge the hard parts honestly. Being wrong publicly, long periods where the thesis does not work, and the fact that the market can stay against you longer than you expect. Saying this shows you are not romanticising it.
   5. Connect it to the firm's horizon. If they run long-duration strategies, say that you want to build ten years of knowledge in a sector rather than rotate every two.

   Where candidates lose it

   An ambitious answer about starting your own fund. In an asset management interview that signals you will leave. Also, do not describe it as your 'passion' without evidence; describe the daily work and why it suits you.

   Expect next

   • What would make you leave?
   • Where do you want to be in ten years?
   • What is the hardest part of this job?

3. 023What got you interested in investing, and what has changed since then?Career and fitIntermediatefirst roundMorningstarEquity Research · Chicago · 2023BLBlackRockInvestment Research · New York · 2026

   Say this

   The 'what has changed' half is the real question. It is asking whether you have learned anything, so the answer should describe a specific belief you held early and abandoned with evidence.

   Then walk it

   1. The origin should be concrete and modest. A first purchase, a company you knew through family, a competition, a book that made you look at an annual report.
   2. Then the evolution, which is where the substance is. 'I started out buying cheap stocks on low P/E and learned that cheap usually means something is broken' is a real answer.
   3. Or: 'I used to think a good product meant a good investment, and I learned that a great company at the wrong price is a bad investment.'
   4. Support it with the specific position that taught you, including the loss. Losses are more persuasive than wins because they are harder to fake.
   5. Close with the principle you now apply and how it shows up in your process. That converts a personal story into evidence of a method.

   Where candidates lose it

   Telling the origin story and skipping the evolution. Also the stock answer of 'I bought Apple at 15 and it went up'. Luck is not a philosophy; what you changed your mind about is.

   Expect next

   • What would you have done differently if you could go back to when you started?
   • What is your investment philosophy?
   • Tell me about a position you got wrong.

4. 024What is an interesting company you have looked at recently?Stock pitchIntermediatefirst roundWMWellington ManagementPortfolio Management · Boston · 2019Carlyle GroupGeneralist · New York · 2015

   Say this

   Treat it as a compressed pitch. Name the company, why it is interesting rather than just good, what the debate is, and where you come out. 'Interesting' means there is genuine disagreement about it.

   Then walk it

   1. Pick something with a controversy. A company everyone agrees is excellent is not interesting; it is consensus. The interesting ones have a real bear case.
   2. Frame it as the debate: 'the bulls say the new segment re-rates the whole company, the bears say it is a low-margin distraction, and the disclosure does not settle it.'
   3. Then your position and the evidence that moved you.
   4. Then be explicit about what you do not know. 'I have not been able to verify the segment margin, which is why I have not sized it.' Admitting the gap is credibility, not weakness.
   5. Have two ready: one long, one short or avoid. Being able to argue a negative case shows you are not just pattern-matching to good news.

   Where candidates lose it

   Naming a mega-cap with no controversy, or a company you cannot describe financially. Expect immediate follow-ups on multiple, growth and margin, and have those numbers at hand.

   Expect next

   • What does it trade at?
   • What is the bear case?
   • Would you buy it here?

5. 025How large is the hedge fund industry?Industry knowledgeIntermediatetechnicalMan GroupEquity Hedge · London · 2016

   Say this

   Roughly $4 to $5 trillion in assets under management globally, across something like 10,000 funds. If you do not know the figure, build it: the largest firms run $50 to $100 billion each, and the top twenty or so account for a large share of the total.

   Then walk it

   1. The headline number is around $4 to $5 trillion, which is worth knowing if you are interviewing at a hedge fund.
   2. If you are unsure, derive it. The biggest multi-managers run on the order of $60 to $100 billion. Twenty firms at an average of $50 billion is a trillion, and the long tail of thousands of smaller funds adds several more.
   3. For context, that is small relative to global equity market capitalisation of well over $100 trillion, and small relative to the roughly $12 trillion BlackRock alone manages. Hedge funds punch above their weight because of leverage and turnover, not size.
   4. The structural point worth adding: assets have concentrated heavily into a handful of large multi-manager platforms over the past decade, while the number of small funds has fallen. That concentration is the defining industry trend.
   5. And the fee model has moved with it: pass-through expenses at the big platforms rather than the traditional two and twenty.

   Where candidates lose it

   Guessing wildly with no derivation, or quoting a number you cannot contextualise. Being asked this at a hedge fund is a test of whether you know the industry you are applying to. Know the figure and one structural trend.

   Expect next

   • How has that changed in the last decade?
   • What is a multi-manager platform?
   • Why do you want to work at a hedge fund rather than long only?

6. 026What makes up a fund's net asset value?Industry knowledgeCoretechnicalMan GroupEquity Hedge · Boston · 2019

   Say this

   The market value of everything the fund owns, less everything it owes, divided by units outstanding. Assets are the positions plus cash and receivables; liabilities are shorts, borrowings, accrued fees and payables.

   Then walk it

   1. Assets: the mark-to-market value of long positions, cash, margin held at the prime broker, dividends and interest receivable, and unrealised gains on derivatives.
   2. Liabilities: short positions valued at market, leverage and margin borrowings, accrued management and performance fees, redemptions payable, and unrealised losses on derivatives.
   3. Divide the net figure by units outstanding to get NAV per unit. That per-unit figure is what investors subscribe and redeem at.
   4. The judgement sits in valuation. Liquid listed equities are straightforward. Illiquid or level three assets are marked to model, and that is where NAV becomes an estimate rather than a fact.
   5. Which is why the practical questions matter: who strikes the NAV, how often, and is there an independent administrator? A manager marking its own illiquid book is a governance concern, and saying so shows you understand why the question is asked.

   Where candidates lose it

   Giving the formula and stopping. The interesting content is valuation of illiquid positions and the role of the independent administrator. That is what an operations-aware investor actually cares about.

   Expect next

   • How do you value a level three asset?
   • Who strikes the NAV?
   • What is a side pocket?

7. 027How would you evaluate an LP stake in a fund, and how much would you pay for it?ValuationHardsuperdayBGBaupost GroupEquity Hedge · Boston · 2018

   Say this

   Start from reported NAV, then adjust it. You are buying the underlying assets plus the unfunded commitment and minus the fees, so the price is NAV adjusted for your own view of the marks, liquidity and remaining fee drag.

   Then walk it

   1. Reported NAV is the starting point, not the answer. Look through to the underlying positions and form your own view on the marks, especially anything illiquid or level three.
   2. Adjust for the fee drag on the remaining life: management fees on committed capital plus carry on future gains. That can be several percent of value in a fund with years left.
   3. For a closed-end structure, factor the unfunded commitment. You are buying an obligation to put in more money, and that has a cost and a risk.
   4. Then discount for illiquidity and for information asymmetry. The seller knows more than you, and there is a reason they are selling. Secondaries typically transact at a discount to NAV for exactly this reason, though quality assets can clear at or above.
   5. Then the vintage and the J-curve position. A fund three years in with assets marked at cost is a very different proposition from one seven years in with a clear path to exit.
   6. So my answer would be a percentage of NAV with the adjustments itemised, and I would say which adjustment I am least confident about.

   Where candidates lose it

   Answering 'NAV'. If it were NAV there would be no question. The expected content is the fee drag, the unfunded commitment, the illiquidity discount and adverse selection. Name the seller's information advantage explicitly.

   Expect next

   • Why is the seller selling?
   • How would you diligence the marks?
   • What discount to NAV would you want?

8. 028How would you perform a whitespace analysis?Company analysisHardtechnicalViking Global InvestorsQuantitative Research · New York · 2024

   Say this

   Map what the company currently sells to whom, map the total set of customers and products it could serve, and the gap between them is the whitespace. Then test whether the company can actually reach it.

   Then walk it

   1. Build the current position first: revenue split by product, by customer segment, by geography. You need the base to measure the gap from.
   2. Then size the addressable set honestly, bottom-up. Number of potential customers times realistic spend per customer, not a top-down market report number that includes everyone.
   3. The whitespace is the difference: customers in the addressable set who do not buy, and products the existing customers buy from someone else. The second is usually the higher-probability opportunity, because the relationship already exists.
   4. Then the feasibility test, which is where most whitespace analyses fail. Does the company have the product, the sales capacity and the right to win? Whitespace that requires capability it does not have is not an opportunity, it is a wish.
   5. Then quantify what the market is paying for. If the current price implies the company captures a third of the whitespace, and your work says it captures a tenth, you have a short. That conversion from market map to expectation is the actual investment output.

   Where candidates lose it

   Producing a large total addressable market number and calling it whitespace. The analytical value is entirely in the feasibility filter and in converting the result into what is priced in.

   Expect next

   • How do you size a market bottom-up?
   • How much of that is in the price?
   • How would you verify penetration rates?

9. 029How do you construct a factor, and how would you decide whether it is real?Quantitative researchHardtechnicalACAQR Capital ManagementInvestment Research · New York · 2021

   Say this

   Define the signal, rank the universe on it, form long-short portfolios from the extremes, and measure the spread after controlling for known factors. It is real only if it survives transaction costs, out-of-sample testing and an economic explanation.

   Then walk it

   1. Construction: choose the metric, neutralise for size, sector and region so you are not just picking up a sector bet, then sort into quantiles and go long the top and short the bottom with rebalancing at a defined frequency.
   2. Measure the spread return, its volatility, the information ratio, and the turnover it requires. Turnover matters because a signal that needs daily rebalancing can be profitable on paper and unprofitable after costs.
   3. Control for known factors. If your new signal's returns disappear once you regress against value, momentum, quality and size, you have rediscovered an existing factor with a new name.
   4. Then the tests that actually matter: out-of-sample and out-of-region performance, stability across sub-periods, and how many specifications you tried before finding this one. Data mining is the default explanation for any new factor.
   5. And demand an economic story. A factor should be compensation for a risk, or exploitation of a behavioural bias, or a structural constraint on other investors. Without that, decay after publication is the base case.
   6. The honest position: most published factors do not survive replication, so the prior on any new one should be skeptical.

   Where candidates lose it

   Describing the mechanics with no discussion of multiple testing and data mining. The intellectual content of modern factor research is that backtests are easy and robustness is hard. Say so.

   Expect next

   • How would you optimise the construction?
   • Why do factors decay after publication?
   • How would you know if you had overfitted?

10. 030What would you have done differently if you could go back to when you started investing?Career and fitIntermediatefirst roundMorningstarEquity Research · Chicago · 2023

    Say this

    Name one specific mistake and the process change it produced. The answer should be a lesson about method, not about a stock you wish you had bought.

    Then walk it

    1. Good answers are about process: position sizing, selling too early, anchoring on purchase price, not writing the thesis down, trading on narrative rather than numbers.
    2. Make it concrete: 'I held a position through three quarters of deteriorating gross margin because I had decided I liked the company. Now I write down in advance what would falsify the thesis, and I check it every quarter.'
    3. The best version includes a behavioural insight about yourself. Knowing your own failure mode is what separates people who improve from people who repeat.
    4. Avoid 'I wish I had started earlier' and 'I wish I had bought more of the winner'. Neither is a lesson and both are things everyone says.
    5. Close with the current habit it produced, so the change is evidenced rather than claimed.

    Where candidates lose it

    Answering with a missed opportunity. That is regret, not learning, and it implies your main reflection is that you should have taken more risk. The expected answer is a process improvement born from a loss.

    Expect next

    • How do you avoid that now?
    • Tell me about a time you were wrong and changed your mind.
    • How do you decide when to sell?
