Likely Vue Developer interview questions
1. Tell us about your experience with Vue.js. What versions have you used?
Mention specific projects, versions (2/3), and key features you've worked with (components, directives, lifecycle hooks).
2. How do you structure a Vue.js project? Walk us through your typical folder organization.
Discuss logical separation: components, views, stores, services, utils; mention naming conventions and scalability considerations.
3. Describe a time when you had to debug a complex issue in a Vue application. How did you approach it?
Show systematic troubleshooting: used Vue DevTools, identified data flow problems, checked lifecycle hooks, and explain the resolution.
4. What's the difference between v-if and v-show? When would you use each?
v-if removes from DOM (higher cost to toggle), v-show uses CSS display (better for frequent toggling); discuss performance implications.
5. How do you manage state in your Vue applications? Have you used Vuex or Pinia?
Explain store structure, mutations/actions, when to use them vs. component state, and how you organize modules for large apps.
6. What are computed properties and watchers? How do you decide which to use?
Computed: derived data, cached, reactive; Watchers: side effects, deep watching; discuss performance and use case trade-offs.
7. Explain component communication in Vue. How do you handle deeply nested component data passing?
Props down/events up, provide/inject, Vuex/Pinia, event bus; address prop drilling problems and when each pattern is appropriate.
8. How do you optimize performance in a large-scale Vue application?
Code splitting, lazy loading routes, virtual scrolling, memoization, avoiding unnecessary re-renders, image optimization, production build size.
9. What's the difference between Vue 2 and Vue 3? How would you migrate a Vue 2 app?
Composition API vs Options API, better TypeScript support, Teleport, improved reactivity; discuss migration challenges and tooling.
10. Describe your approach to testing Vue components. What tools do you prefer?
Unit tests (Vitest, Jest), component tests (Vue Test Utils), E2E (Cypress, Playwright); discuss snapshot testing and coverage strategies.
11. How would you implement a complex form with validation, conditional fields, and async submission in Vue?
Form state management, validation libraries (Vuelidate, VeeValidate), handling async operations, error states, and UX considerations.
12. Design a scalable Vue application architecture for a team of 5+ developers. What patterns, tooling, and conventions would you establish?
Monorepo vs. mono-app, design patterns (store, composables), linting/formatting (ESLint, Prettier), testing standards, CI/CD, and documentation.
