Quiz: Design Patterns | QuizMaker

Move beyond surface-level recall with **Design Patterns** in this 11-question interview-focused practice test. It is structured for Java interviews and backend revision, and the attempt uses an 8-minute timer so you can practise with clear conditions. ⚙️ **Skills tested:** The questions cover Builder pattern and immutable object construction; composition-based behaviour extension; avoiding unnecessary pattern complexity; interface-based legacy API integration; wrapping service behaviour without class changes; and Adapter and Decorator patterns. Rather than rewarding definitions alone, the set tests how concepts behave under constraints, failures, and changing requirements. *Treat incorrect answers as design-review notes: identify the overlooked constraint and practise defending a safer alternative.*
