Practice questions for the Singapore loop
Matched to the topics IMC Trading draws on for the roles it hires here: probability, mental maths, market making, statistics, brainteaser, algorithms, c++ and systems. Written originally for this platform.
Market makingHardTrading round
You are quoting a market and get lifted five times in a row on the offer, in full size, by the same counterparty. Nothing else in the market has moved. What do you do?
StatisticsHardResearch round
Your alpha shows a strong in-sample relationship with next-day returns, but the effect halves out of sample. Give three explanations that are not overfitting.
AlgorithmsHardEngineering round
You receive a stream of order-book updates and must report the maximum trade price in the last N events at every step. How?
C++ and systemsHardEngineering round
Your median tick-to-trade latency is fine but the 99.9th percentile is ten times worse. Name the likely causes.
BrainteaserHardFirst round

Two people independently pick a real number uniformly from [0, 1]. What is the probability the two numbers differ by more than 0.25?
ProbabilityStandardFirst round

Methodology
Figures are expressed as annual total compensation (base salary plus expected performance bonus) in the reference market's local currency, converted from a US dollar base. They describe typical market ranges rather than any individual offer, and exclude sign-on payments, deferred equity and carried interest. Portfolio-manager figures reflect formulaic profit-share arrangements and are therefore far more dispersed than any other role.

Modelled bands describe the market, not an individual offer. Where an employer states pay, the stated figure is used and labelled as such.
