5+ curated questions with the same answer shape every time: quick recap, deep dive, pitfalls, and follow-ups. Coverage includes pattern matching ruby3, numbered block parameters, endless methods, data define, and more.

Topics follow a teaching order. Each answer ends with a clear Next question control so you can move forward without hunting the list.
Modern Ruby interview questions should test whether a developer understands the contracts behind newer syntax, not whether they can list release notes. This module teaches structural pattern matching, concise block parameters, endless method definitions, Data value objects, and frozen string literals through small examples and explicit boundaries. Each lesson explains what the feature changes, what remains ordinary Ruby behaviour, where the shorthand improves clarity, and where a conventional class, method, block, or mutable string is safer.
