Sample interview questions
How would you design a backend service that safely supports deployment and runtime operations for customer web applications?

I would begin by defining clear service boundaries, ownership, API contracts, and failure modes. I would use asynchronous workflows for long-running deployment tasks, durable state tracking, idempotency keys, observability, and role-based access controls. I would also design for retries, rollback paths, rate limits, and measurable service-level objectives before scaling the implementation.

Describe how you investigate and prevent a recurring production incident.

I first stabilize customer impact through mitigation, then use logs, metrics, traces, recent changes, and dependency health data to isolate the failure mode. After documenting a blameless root-cause analysis, I prioritize durable fixes such as automated guardrails, better alerts, capacity controls, tests, or architectural changes. I validate the fix in a controlled rollout and track whether the recurrence rate and customer impact decline.

What factors guide your choice between CDN caching, edge compute, and an origin backend service?

I assess latency requirements, personalization, data consistency, execution limits, security needs, and operational complexity. Static or safely cacheable content belongs at the CDN, lightweight request transformations and geographically close logic can fit edge runtimes, and stateful or compute-intensive workflows generally remain at the origin. I make cache keys, invalidation behavior, and observability explicit so the system remains correct as it scales.

How do you approach data-model and query optimization for a high-traffic production system?

I start with access patterns and measure real query behavior using database metrics and execution plans. I choose indexes and schema constraints that support critical reads and writes, avoid unnecessary joins or unbounded scans, and use pagination and connection management appropriately. For changes, I plan backward-compatible migrations, evaluate locking and replication impact, and monitor performance through rollout.

How do you use AI-assisted development without compromising code quality or reliability?

I use AI to accelerate exploration, scaffolding, test generation, and documentation, but I retain responsibility for architecture and correctness. I validate generated code through review, automated tests, security checks, and production-safe rollout practices. For infrastructure and critical paths, I treat AI output as an untrusted draft and confirm assumptions against system requirements and operational evidence.
