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.

- How would you know a systematic strategy had stopped working rather than just having a bad month?
- Which would you rather work in?
