Interview Prompt
A brokerage platform processes about 2 billion trade execution events a day, and two teams read them: risk wants intraday position dashboards that stay within a few seconds of the market, while regulatory reporting needs every trade counted exactly once in the end-of-day books. Trades arrive out of order and some are corrected hours after execution, so the design has to reconcile late and amended fills without double-counting or dropping them.
