JPMorgan's system-design rounds centre on high-volume, high-correctness banking systems.
In 2026 expect prompts on processing millions of card transactions a day with fraud checks in the authorisation path, a retail-bank ledger that must always balance, and near-real-time multi-channel customer notifications. Interviewers reward separating the low-latency authorisation path from asynchronous fraud scoring, using an append-only double-entry ledger with careful concurrency control, and guaranteeing at-least-once delivery with deduplication. The domain is unforgiving: money must never be lost or double-counted, so precise reasoning about consistency, idempotency, and failure handling is what distinguishes strong answers.
