Design a cross-product user journey data architecture
This tests portfolio-scale data platform design. A strong answer outlines streaming event ingestion, a unified identity graph, consent-aware PII vaults, and schema registries with data contracts.
This tests whether you can design a portfolio-scale data platform without collapsing independent product boundaries. A strong answer covers four layers: streaming event collection with SDKs, a central data lake with unified identity resolution, privacy vaults that enforce consent per jurisdiction, and schema registries with data contracts to handle independent product evolution. Red flag: recommending a single shared relational database, ignoring GDPR/CCPA deletion propagation, or proposing rigid upfront schemas that break product autonomy.
