This question evaluates a candidate's ability to design scalable, multi-tenant distributed analytics platforms, testing competencies in distributed systems architecture, data layout and storage, query planning and execution, metadata management, consistency and replication strategies, fault tolerance, observability, and capacity planning.

Design a distributed system to satisfy an open-ended product requirement. Clearly state and validate assumptions; define SLAs and workloads; model data and APIs; choose sharding and replication strategies; select a consistency model and justify trade-offs (e.g., CAP, latency vs. throughput); handle failures (network partitions, node crashes, slow nodes) with leader election, retries, idempotency, and backpressure; ensure observability (metrics, logs, tracing) and capacity planning; describe testing, deployment, and rollback procedures; and sketch a high-level architecture and communication patterns.
