Frontend interviews often combine theory with hands-on experience. Candidates are usually tested on HTML, CSS, and JavaScript basics before moving into advanced topics. Interviewers might ask about the purpose of common HTML tags, how CSS box models work, how selector specificity is calculated, and which layout systems (like Flexbox or Grid) are appropriate for different use cases. A solid foundation in these areas can make real-world development much smoother.
JavaScript questions tend to go deeper. You might be asked to explain closures, variable scope, or how the event loop works. Understanding asynchronous programming through Promises and async/await is especially useful. Coding tasks involving array deduplication, deep cloning, or flattening nested arrays are common—they test both your logical thinking and your ability to write clean, efficient code.
With React and Vue widely used across the industry, it’s no surprise that interviewers focus on them. You should be ready to explain React lifecycle methods, hooks, and how you handle state. If the job involves Vue, understanding its reactivity model and how components communicate is important. Going beyond surface-level usage and showing that you understand the internal mechanisms can set you apart.
Interviewers also care about how familiar you are with modern build tools. Webpack is a frequent topic, especially around optimization techniques like code splitting, tree shaking, and lazy loading. Don’t forget about Git either, since most frontend projects involve collaboration across teams.
Your past projects often become part of the conversation. Be ready to talk about real scenarios where you improved load time, addressed browser quirks, or made a design work well on different screen sizes. During live coding sessions or bug fixes, staying calm and demonstrating a clear thought process is often more valuable than rushing to write perfect code.
Soft skills matter, too. Many behavioral interviewers will want to know how you approach teamwork or deal with setbacks. Having one or two real stories ready—maybe about debugging an issue under pressure or working across disciplines—helps add authenticity to your answers.
In short, frontend interview preparation is about more than just technical drills. Build a balanced mix of coding skills, framework knowledge, tooling familiarity, and communication confidence. That way, you’re not just ready to answer questions—you’re ready to do the job.
