Hedge Funds interview preparation
Long-short equity, macro, event-driven, distressed, multi-manager platforms and the Indian Category III landscape. 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.

002Explain the difference between discretionary and systematic trading.Man GroupGeneralist · London · 2023
Say this
A discretionary manager makes the decision on each trade, using a rules-guided but human judgement. A systematic manager makes the decision once, in code, and then the rules trade without intervention. The real difference is where the human judgement sits: in the position or in the process.
Then walk it
- Discretionary: deep work on few positions. A macro PM might run fifteen expressions of four themes. Breadth is low, so the edge has to be depth of insight.
- Systematic: shallow work on many positions. A trend or stat arb book may hold thousands of instruments, each with a small expected edge, and the edge is breadth plus discipline.
- The fundamental law of active management is the clean way to say it: information ratio is roughly skill times the square root of breadth. Discretionary buys the skill term, systematic buys the breadth term.
- Capacity differs. Systematic strategies hit capacity limits in the market microstructure and can be measured; discretionary capacity is limited by how many names one human can genuinely know.
- Failure modes differ too. Discretionary fails through anchoring, averaging down and story-telling. Systematic fails through overfitting, regime change and everyone crowding the same signal.
- The blurred middle is where most large firms live now: quantamental. Human thesis, systematic screening, portfolio construction and risk done by the machine. Man Group itself runs both AHL on the systematic side and discretionary equity books, which is worth naming if you are sitting there.
Where candidates lose it
Framing it as 'humans versus computers'. Discretionary PMs use enormous amounts of quantitative tooling, and systematic researchers make thousands of judgement calls when specifying a model. Say where the judgement sits instead, and mention the fundamental law if you want to sound like you have thought about it rather than read about it.
Expect next
- Which has more capacity, and why?
- How would you know a systematic strategy had stopped working rather than just having a bad month?
- Which would you rather work in?

031How do you understand portfolio risk?Man GroupInvestment Management · Boston · 2022
Say this
As three separate questions, not one number. How much do I expect to lose in a normal month, what happens in a bad one, and what am I unknowingly concentrated in? Volatility answers the first, stress tests answer the second, and factor decomposition answers the third.
Then walk it
- Layer one, the normal case: volatility, VaR and contribution to risk per position. Useful for sizing and for spotting that one position is carrying a third of the risk.
- Layer two, the bad case: stress tests and scenarios. Rerun the book through 2008, March 2020, the 2021 momentum unwind, a 100 basis point rate shock. This is where you learn the hedges stop working.
- Layer three, the hidden case: factor and thematic decomposition. What is the book's net exposure to growth, to momentum, to oil, to the dollar, to one supply chain? Most surprises are a concentration nobody had named.
- Then liquidity risk, which sits underneath all of it. Days to exit at 20 percent of volume, and what the book looks like if you have to raise 20 percent of cash in a week. Illiquidity converts a paper loss into a realised one.
- And correlation instability, which is the one that actually hurts. Correlations rise in stress, so a diversified book is less diversified precisely when it matters. I would assume correlations go to one in the tail rather than trusting the historical matrix.
- The limitation to volunteer: every number here is backward looking and conditional on a covariance matrix estimated from a period that may not resemble the next one. That is why hard limits and drawdown stops exist alongside the models, rather than instead of them.
Where candidates lose it
Answering only with VaR or only with volatility. A single risk number is the wrong shape of answer to this question. Name the three layers, then add liquidity and correlation instability, and say explicitly that the models are backward looking. That last admission is what a risk-focused interviewer is listening for.
Expect next
- What does VaR miss?
- How would you stress test a long-short equity book?
- How do you think about transaction cost?

039How do you think about transaction cost?Man GroupInvestment Management · Boston · 2022
Say this
In three buckets: the explicit costs, the spread, and market impact. The first two are small and easy to measure; impact is the big one and it scales with size, so for any strategy with turnover, cost is not a friction on the return, it is a constraint on the strategy.
Then walk it
- Explicit: commissions, exchange fees, taxes such as stamp duty in the UK or STT in India. A few basis points, predictable, and in India securities transaction tax genuinely changes which strategies are viable.
- Spread: you cross half the bid-ask to trade immediately. In a liquid large cap that is one or two basis points; in a mid cap it can be 30.
- Impact: your own order moves the price. The standard working model is that impact grows roughly with the square root of the order size as a fraction of daily volume, so trading 10 percent of ADV costs far more than twice trading 5 percent.
- Then the cost nobody puts on the invoice: opportunity cost and delay. Trading slowly reduces impact and increases the risk the price runs away from you. That trade-off is exactly what an execution algorithm is solving, and implementation shortfall against the arrival price is the right way to measure the whole thing.
- The practical consequence is that cost has to be inside the signal, not after it. If a signal has 20 basis points of gross edge and 15 of round-trip cost, it should be traded slowly, netted against other signals, or not traded at all.
- One number to make it real: a book turning over 200 percent a year at 15 basis points round trip pays 60 basis points annually. That is the difference between a good year and an average one, and it is why netting flows across pods is a genuine advantage of a large platform.
Where candidates lose it
Answering with commissions and the spread and missing impact. Impact is the entire subject for anyone running real size, and the square-root rule plus implementation shortfall is the vocabulary that shows you have looked at execution data rather than a textbook. Also mention that cost belongs inside the signal, not subtracted afterwards.
Expect next
- How would you measure your own market impact?
- How does cost change the optimal holding period?
- What is implementation shortfall?

068What makes up a NAV?Man GroupEquity Hedge · Boston · 2019
Say this
Total assets at fair value, minus total liabilities, divided by units outstanding. On a hedge fund the interesting parts are all in the details: how positions are priced, and everything that sits in liabilities, which includes the short book, the financing and the accrued fees.
Then walk it
- Assets: long positions at fair value, cash and cash equivalents, margin and collateral posted at the prime broker, receivables from unsettled trades, dividends and interest receivable, and the positive mark-to-market on derivatives.
- Liabilities, which is where hedge funds differ from a mutual fund: the market value of short positions, margin loans and repo borrowings, negative derivative marks, payables on unsettled trades, dividends payable on shorts, accrued borrow fees, plus accrued management and performance fees and fund expenses.
- So the accruals are a real part of the number. An accrued performance fee is a liability that reduces NAV even though it has not been paid, which is why NAV can be quoted gross and net of fees and the difference matters.
- Pricing policy is the substance of the answer. Exchange-traded positions at the official close, over-the-counter instruments from broker quotes or a model, and illiquid positions by a documented valuation policy. The hierarchy is level one, two and three, and the percentage in each tells you how much of the NAV is opinion.
- Governance is the other half. An independent administrator strikes the NAV, the prime broker's records are reconciled against it, a pricing committee approves level three marks, and the auditor tests them annually. The manager should not be the sole source of a price.
- One practical detail worth having: NAV is usually struck monthly for subscriptions and redemptions but estimated daily for risk, and the two can differ. Investors transact on the official NAV, so the gap between the daily estimate and the final struck number is itself a control worth monitoring.
Where candidates lose it
Giving the mutual fund answer, assets minus liabilities, and missing that the short book and the financing sit in liabilities. Also missing the accrued performance fee. The question in a hedge fund interview is really about pricing policy and who strikes the number, so say level one, two and three, and say the administrator's role.
Expect next
- Who should strike the NAV and why not the manager?
- How would you value a level three position?
- What is the difference between gross and net NAV?
