Ruby Spec Interview Guide

Ruby-specific checklist for spec interviews and implementation. For underlying Ruby conventions, consult the sorah-guides:ruby skill. Project-specific conventions always take priority.

Interview Checklist

When interviewing a spec for a Ruby project, verify these areas are fully specified:

Architecture & Design

• Service object class names, method signatures, and return types
• Module/namespace hierarchy and file layout
• Which value objects use Struct/Data vs plain classes
• include vs extend decisions for shared behavior

Behavior & Logic

• Method signatures: keyword arguments, required vs optional parameters
• Error handling: which specific exceptions are rescued and why
• Nil handling strategy for each interface boundary

Testing

• RSpec structure: which spec types cover each component (unit, integration)
• Factory definitions needed for test data
• Error path and edge case coverage expectations

Security

• Password/credential hashing algorithm and cost factor
• Token storage format (hashed, never plaintext)
• Secret comparison approach (constant-time)
