Argue for declarative or imperative feature platforms with trade-offs
This tests whether you weigh control flow against data flow. A strong answer argues from org maturity: declarative systems abstract DAG topology, while imperative ones offer Spark control at the cost of manual idempotency. Red flag: ignoring org culture.
This tests whether you distinguish control flow from data flow and who owns state and dependencies. A strong answer picks a side based on org maturity: declarative platforms abstract DAG topology, checkpointing, schema evolution, and data contracts, but sacrifice node-level tuning; imperative platforms maximize control via custom Spark jobs, yet burden users with manual idempotency and dependency wiring. Red flag: treating the choice as purely technical or claiming one is universally superior without addressing FinOps and team skill depth.
