Execution Quant Interview Cycle Review

Execution quant interview cycle review covering order types, book mechanics, slippage, market impact, algorithms, routing, and final drills.

Candidates consolidating order book, execution cost, impact, and routing prep.

Review the order life cycle

Be able to explain decision price, order type, routing, queue position, fill probability, execution price, and post-trade cost analysis.

Review microstructure mechanics

Know spreads, depth, limit order books, order flow, adverse selection, latency, market impact, and liquidity metrics at interview depth.

Review execution algorithms

Understand TWAP, VWAP, participation, smart routing, dark pools, urgency controls, and why no algorithm is universally best.

Concrete final drill

Explain how you would execute a large order, estimate slippage, monitor impact, and decide whether passive or aggressive trading is better.

Common mistakes

Candidates often discuss signal quality and skip implementation. Execution interviews test whether theoretical edge survives real trading costs.
