Vue.js Interview Questions & Assessment
Assess Vue.js proficiency including Composition API, reactivity system, Vuex/Pinia, Vue Router, and single-file components.
Why Vue.js Matters
Vue.js is widely adopted in Asia, Europe, and by companies like Alibaba, Xiaomi, and GitLab. Its gentle learning curve makes it a popular choice for teams transitioning from jQuery or building new SPAs.
Sample Interview Questions

Compare the Options API and Composition API. When would you use each?
How do provide/inject work? When would you use them over props or a store?
