Senior Front-End Developer

Senior-level Front-End Developer (Vue.js) with strong commercial experience (3+ years, including ~5 years with Vue.js), solid knowledge of Vue 3/Composition API, and at least basic TypeScript skills. The role suits someone experienced in building pixel-perfect UIs, working with component libraries like Vuetify, and collaborating in remote Scrum teams. The candidate should be comfortable with tasks like feature development, refactoring, unit testing, code reviews, and close collaboration with product/design teams.

1. What are the key differences between Vue 2 and Vue 3, and why would you choose Vue 3?
   Vue 3 introduces the Composition API, better TypeScript support, and improved performance due to a rewritten reactivity system. It’s preferred for scalability and maintainability in large applications.

2. How does the Vue Composition API improve code organization compared to the Options API?
   The Composition API allows grouping logic by feature instead of by option type, making complex components easier to read, reuse, and test.

3. How do you manage state in a large Vue.js application?
   State can be managed using tools like Vuex or Pinia, separating global state from local component state and ensuring predictable data flow.

4. What are some best practices for writing scalable TypeScript in Vue projects?
   Use strict typing for props, emits, and state, leverage interfaces, and avoid any to maintain type safety and improve developer experience.

5. How do you ensure pixel-perfect implementation from design files?
   By carefully following design specs (e.g., Figma), using consistent spacing, typography, and validating UI across browsers and screen sizes.

6. What is your approach to component reusability in Vue?
   Break UI into small, reusable components with clear props and events, and avoid duplication by abstracting common logic into composables.

7. How do you optimize performance in a Vue.js application?
   Use lazy loading, code splitting, memoization (computed), and avoid unnecessary re-renders with proper key usage and efficient state updates.

8. How do you write and structure unit tests for Vue components?
   Use tools like Jest and Vue Test Utils to test component behavior, props, and emitted events, focusing on logic rather than implementation details.

9. What is your experience with Material Design frameworks like Vuetify?
   Vuetify provides pre-built components following Material Design, speeding up development while ensuring consistency; customization is often done via themes and overrides.

10. How do you handle collaboration in a remote Agile/Scrum team?
    By actively participating in stand-ups, code reviews, and sprint planning, maintaining clear communication, and documenting decisions to keep alignment across distributed teams.
