Sample interview questions
How would you design an indexing pipeline that supports both keyword and vector search at high scale?

I would separate ingestion, transformation, indexing, and serving into independently scalable components, with durable queues between stages. I would define idempotent writes, versioned index artifacts, backpressure controls, and observability for freshness, throughput, failures, and resource use. The design would also include safe rollout and rollback mechanisms for schema and ranking changes.

Describe how you would investigate a sudden increase in search latency in production.

I would first assess scope through dashboards and traces, separating query-serving latency from network, storage, cache, and downstream dependency delays. I would compare affected traffic segments, recent deploys, query patterns, and resource saturation, then mitigate with rollback, traffic shaping, cache adjustments, or capacity changes as appropriate. After recovery, I would document root cause and add alerts or tests to prevent recurrence.

What practices do you use to make distributed systems resilient to partial failures?

I use explicit timeouts, bounded retries with jitter, circuit breakers, idempotency keys, dead-letter handling, and graceful degradation. I also design for replication, controlled failover, and clear consistency guarantees rather than assuming all dependencies are always available. Regular failure testing and actionable telemetry are essential to verify these mechanisms.

How do you balance fast feature delivery with reliability and code quality?

I break work into small, observable releases behind feature flags and establish non-negotiable quality controls such as reviews, automated tests, and production metrics. I prioritize risks based on customer impact and use incremental delivery to gather evidence before broad rollout. When technical debt affects reliability or delivery speed, I make its cost visible and propose a focused remediation plan.

What is your approach to participating in an on-call rotation?

I treat on-call as a shared engineering responsibility and ensure services have useful runbooks, dashboards, alerts, and clear ownership. During an incident, I communicate status concisely, stabilize the service first, and coordinate escalation when needed. Afterwards, I contribute to blameless post-incident follow-up and automate recurring operational work.
