Deep explanation
System design: a financial research assistant with Production Failure
Principal system design interview question on Production Failure within AI Career & Behavioral.
Quick answer
A financial research assistant should answer from versioned filings, news, and market data, and it should tie every material claim to a source it actually retrieved. Production failure shows up when retrieval is stale, a citation does not match the passage, a tool times out, or the answer exceeds its time budget. Detect those with freshness, citation-check, tool-error, and latency monitors, then fall back to a labeled snapshot, an ungrounded-claim drop, or a shorter answer that names the missing data. Roll back by pinning the previous index, prompt, and model route when those monitors breach the release gate.
The interview question
