Code Quality and Review Questions

Evaluating code for correctness, clarity, maintainability, performance, and security and providing actionable feedback. Candidates should be able to identify bugs, logical errors, anti patterns, and algorithmic inefficiencies, and to suggest concrete fixes or refactorings. Reviews should cover naming, modularity, documentation, testability, and design patterns, and recommend appropriate unit and integration tests. Candidates should also diagnose performance issues, reason about trade offs when optimizing, and consider how changes affect reliability and security.
