What is Vue?
Vue is a progressive JavaScript framework for building user interfaces. It pairs a reactive data model with a component system, and it scales from a single enhanced page to a full single-page application without forcing an all-or-nothing rewrite.
Vue interviews probe how reactivity actually works: refs versus reactive objects, computed properties, watchers, and the lifecycle of a component. You will also be asked to compare the Options API with the Composition API and to justify when each one fits.
Beyond the core, expect questions on component communication, slots, Vue Router, and state management with Pinia. Understanding how Vue tracks dependencies is what separates a confident answer from a memorised one.
Reading answers is not the same as giving them. Sit a full mock interview and get scored on how you actually explain them.
