If you are stepping in for a front end developer interview, you need to have some useful front end interview tips to ace the interview process. Front-end development is the process of designing interfaces and components for a website or any application. The user-facing “front†side of any application is developed by a front-end developer.
Given that it is a continually evolving discipline, you need to be prepared well to stand out from the rest. In this blog, we will give you some essential front end interview tips that will help you strengthen your basics and give you the required strategies and tips for the interview day.
Front End Interview Tips to Prepare Your Technical Base
First and foremost, you must be clear with the fundamentals of front end development. Javascript, HTML, and CSS form the core foundation of front end development. Technical questions regarding HTML are often asked as starters, and it is important to know the fundamental concepts.
Learn about browser rendering, Document Object Model (DOM), and Critical Rendering Path, and learn the concepts of reflow and repaint. Often overlooked, understanding how browsers render web pages work can give you an edge in the interview.
Version control: Familiarize yourself with the version control systems like Git. These are the tools that go hand in hand with collaborative development; thus, most organizations would see it as a given if we knew how to use them.
Development tools: Be comfortable with tools like Chrome DevTools, VS Code, and GitHub. Using such tools effectively and correctly could be a game changer in productivity during the development and debugging phase.
If you work through this technical groundwork, you should be in a very good place for most front-end interview settings.
Front End Interview Tips to Master the Core Skills
Building upon the basics of front-end development, you must focus on mastering the core skills in HTML, CSS, and various Javascript frameworks like React, Vue, Angular, etc, or whichever framework you are familiar with.
HTML and CSS: Familiarize yourself with the web page structure and style. Understand how to create semantic HTML, choose the right tags, and utilize CSS for responsiveness. Be prepared to talk about CSS grid, Flexbox, and media queries, which are key to responsive design, during the interview.
Web APIs and JavaScript: Javascript and different frameworks like React and Angular form the most important parts of front-end development. Learning about concepts like asynchronous programming, the event loop, and closures are all crucial to understanding JavaScript. You should also be familiar with web APIs, such as Fetch and Axios, which are often used for handling HTTP requests.
Responsive design: Designing and creating responsive interfaces is a key skill that is tested in the interview. Understand the mobile-first design and progressive enhancement design principles, as well as fluid grids.
Cross-browser compatibility: You must be familiar with ensuring your website works in a variety of browsers and devices. This includes recognizing browser-specific bugs, their workarounds, and feature detection frameworks.
By mastering these core skills, you can easily clear most of the technical questions you face in a front-end developer interview.
Front End Interview Tips to Prepare for JavaScript Coding Questions
Since JavaScript forms the crux of front-end development, you will get a lot of questions about it during your interview. Here are some front end interview tips to help you prepare for the coding questions on Javascript.
Master the basics: Having a strong understanding of basic JavaScript concepts like data types, functions, and scope is a must. Essentially, you need to understand what your writing does before fixing other developers’ code.
You also need to move on to more complex features like closures, promises, async/await, and ES6+ features like destructuring, arrow functions (=>), modules, etc.
When you consider front end vs back end, Front-end development isn’t as “algorithm-heavy†as back-end or full-stack. However, you should still know a few common algorithms (sorting, searching) and data structures (arrays, objects, linked lists).
Practice programming challenges: Keep practicing different coding challenges on LeetCode, HackerRank, or Codewars. If you are lacking in coding skills, you can practice and make them better with enough practice.
Here are some example JavaScript questions:
- Explain the difference between == and === in JavaScript.
- What is a closure in JavaScript? Give an example.
- How does the ‘this’ keyword work in JavaScript?
- Explain the concept of promises in JavaScript.
- How Do you handle errors with promises?
- What are arrow functions in JavaScript, and how do they differ from regular functions?
- What is event delegation in JavaScript?
- Describe the difference between ‘null’ and ‘undefined’ in JavaScript.
