Sample interview questions
I would organize the application by feature or domain, establish a shared component library for reusable UI primitives, and keep data-access logic separate from presentation components. I would define clear state-management boundaries, enforce linting and testing standards, and document architectural conventions so the codebase remains consistent as the team grows.
I first measure performance using browser profiling and real-user metrics, then address the largest bottlenecks. Typical improvements include route-level code splitting, lazy loading, image optimization, avoiding unnecessary renders with memoization where justified, list virtualization, caching API responses, and reducing bundle size.
I begin with semantic HTML and ensure keyboard navigation, visible focus states, proper labels, and logical heading structure. I use ARIA only when native elements are insufficient, test with automated accessibility tools, and manually validate critical flows with keyboard and screen-reader behavior.
I would create a dedicated API layer with typed request and response models, consistent error handling, authentication handling, and caching rules. For GraphQL, I would use a suitable client and colocate queries or fragments with the relevant features; for REST, I would centralize endpoints and normalize shared response behavior.
I focus on the technical goals, such as maintainability, performance, accessibility, and delivery risk, rather than on personal preference. I explain my reasoning with concrete examples or data, listen to alternatives, and support a documented team decision once the tradeoffs have been considered.
