0+ curated questions with the same answer shape every time: quick recap, deep dive, pitfalls, and follow-ups. Coverage includes .
Rails framework interview questions for experienced engineers go beyond the scaffold. This module covers the full Rails request lifecycle (router → middleware stack → controller → model → view/serializer → response), the Rack protocol and how any Ruby object with a call method becomes middleware, how the middleware stack is ordered and how to add custom middleware, the Zeitwerk autoloader and how constant lookup works, Rails engine vs mountable engine, config/initializers execution order, ActiveSupport::Notifications for instrumentation, and common scenario-based questions (why is my middleware not running, what happens when Zeitwerk can't find a constant, how do I debug the request lifecycle). Every answer traces the full path.
