Design a cache specifying data structures used and trade-offs.
Asked in the Round 5 – Technical + Behavioral (Go + Systems Heavy) stage. Treat this as a hands-on design exercise. Explain the cache interface, data structures, eviction and expiration policies, concurrency model, persistence choices, and behavior under failures. Discuss how your design would support low-latency ML inference without serving stale or incorrectly keyed results.
