Pattern Reuse and Design Systems Questions

Focusing on leveraging, creating, and scaling reusable design and engineering patterns across a product or organization. This covers use of component libraries, design systems, templates, and architectural patterns; reasoning about when to reuse versus when to create bespoke solutions; designing abstractions that enable consistency and scalability; handling versioning, documentation, and governance of shared patterns; and evaluating the costs and benefits of reuse including coupling, overgeneralization, and refactor effort. Interviewers evaluate the candidate on their ability to identify opportunities for reuse, communicate reusable abstractions, ensure consistency, and design for long term maintainability and scalability.
