Sample interview questions
How have you designed a scalable Ruby on Rails application for growth?

I start by identifying domain boundaries, expected traffic patterns, and data access bottlenecks. I use clear service boundaries, efficient database indexes and queries, caching where appropriate, background jobs for slow work, and observability to validate performance in production.

How do you maintain quality in a Rails codebase while delivering features quickly?

I use a layered testing strategy with focused unit tests, request or integration tests for important user flows, and code review standards. I also prioritize small, reviewable changes, automated checks in CI, and refactoring when complexity begins to impede safe delivery.

Describe your approach to improving a slow database-backed endpoint.

I first measure the endpoint using application monitoring, logs, and query analysis. I look for N+1 queries, missing indexes, inefficient joins, excessive payloads, and opportunities for caching, then verify the improvement with production-like data and regression tests.

How do you decide when to use Redis in a web application?

I use Redis for short-lived caching, rate limiting, distributed locks, session-related needs, and queue-backed background jobs where fast in-memory access is useful. I avoid treating it as the system of record and define expiration, invalidation, and failure behavior explicitly.

How do you work effectively in a fully remote engineering team?

I communicate progress and risks proactively, document technical decisions, and keep work visible through well-scoped tickets and pull requests. I use asynchronous communication for routine collaboration while scheduling focused discussions for decisions that benefit from real-time alignment.
