Sample interview questions
I would first establish clear service-level indicators for latency, errors, saturation, and dependency health, then use traces, metrics, logs, and traffic segmentation to isolate the source. After validating the failure mode, I would prioritize mitigations such as timeouts, backpressure, caching, query optimization, load shedding, or capacity changes, and follow with a measured rollout and post-incident review.
I would map affected code paths and dependencies, add or strengthen targeted tests, and define observable success and rollback criteria before implementation. I would use incremental changes, feature flags or shadow traffic where feasible, careful code review, and phased deployment so that impact can be detected and reversed quickly.
I focus on a clear customer problem, stable and well-documented interfaces, sensible defaults, authentication and authorization, idempotency, rate limits, and actionable error handling. I also include observability, operational ownership, versioning, and feedback loops so partner teams can adopt the service confidently without requiring constant support.
I would begin with access patterns, consistency requirements, data volume, latency targets, availability needs, and operational tradeoffs. PostgreSQL is appropriate for relational data and transactional consistency, Cassandra for highly scalable distributed write and read patterns with modeled queries, and Redis for low-latency caching, ephemeral state, or data structures rather than durable system-of-record storage.
I explain the customer and business impact first, then present the technical risk, available options, expected cost, and recommendation in concise language. I make assumptions explicit, invite input from affected teams, document the decision, and provide status updates through implementation and validation.
