Trade Execution Quant Interview Guide
Trade execution quant interview guide covering order types, liquidity, slippage, market impact, algorithms, execution risk, and evaluation.
Candidates preparing for trading, execution research, and market microstructure discussions.
Execution turns decisions into fills
A trading decision is not finished when the signal fires; execution determines realized price, completion, timing risk, and market impact.
Start with the objective
An execution answer should state urgency, target quantity, benchmark, liquidity, risk tolerance, and whether completion or price is more important.
Concrete example
A large buy order in a thin stock may need slicing, participation limits, and impact monitoring instead of sending one market order immediately.
Measure realized quality
Use benchmarks such as arrival price, VWAP, implementation shortfall, spread capture, fees, and opportunity cost from missed fills.
Common mistakes
Candidates often optimize only quoted price. Strong execution answers balance fill probability, adverse selection, impact, and completion risk.
