9 Important Questions When Hiring a Front End Developer

Before you hire a front-end developer, think about the skills that are necessary to succeed in your organization. If you've never had to hire a developer before, check out our questions below to find out the necessary skills for successful web development or software engineering. If you're unsure of what to ask before you hire front-end developers for your project, here are some example questions to get the conversation started.

1. What skills are necessary to successful front-end developers?

All front-end developers should be able to explain how they use HTML, CSS, and Javascript to build pages and applications with a responsive design, but even junior developers can explain that. You want a front-end developer who will bring a flash of brilliance to your development needs. You want to know what they have added to their portfolio of skills that makes them stand out from the crowd. Maybe they have an extensive catalog of interactive web application elements or extensive knowledge of have to implement Javascript libraries to get the very best results. Putting the ball in the front-end developer's court is an excellent way to dig into the details about the candidate.

2. What is the web application that you are most proud of?

Looking at a developer's portfolio can be intimidating if you're not used to working with their specialism. But asking them to show you their favorite piece and explain why they like it can tell you a lot about their work process. When interviewing a front-end developer, asking how their best samples relate to your project can also shine a lot of light on the development process. Then you will find out whether they truly understand the programming languages that are necessary to make your project a success.

3. How do you make your web pages user-friendly?

Web design is nothing if it doesn't account for user experience (UX). Visitors to your website or customers using your software will have to interact with the UI, so you need a front-end developer who understands how to make websites that work and help visitors/customers find what they need.

  • A front-end developer should be able to explain how they:
  • Use HTML and CSS to make attractive looking websites
  • Use Javascript to make web pages interactive
  • Write code that is optimized for speed

UX best practices include breaking up information for easy reading, avoiding extremely long drop-down menus, and layouts that account for distracted visitors. The best front-end developers will be able to marry technical skills with UX best practices, instead of flooding every web application with attractive but unintuitive features.

4. How do you make your code easy for other front end developers to read?

Even if you find the perfect programmer for your project, that doesn't mean that you won't want to make changes in the future. That's why all good front-end developers need to make human-readable code. The developer should be able to leave clear and concise comments in the code that explain their thought process. Software development also needs to be as succinct as possible - web applications and software interfaces can't have a lot of waste code or they start to slow down.

5. Why would you use a CSS preprocessor?

CSS is necessary for front-end development, but the language needs support to really take development to the next level. Front-end developers should be able to explain at least one CSS preprocessor and how it is used to improve CSS's capabilities. A front-end developer should explain how using a preprocessor like Sass or Less allows them to include variables, nesting, inheritance, and mixins. Ask potential hires how they would include logic to take your project to the next level.

6. Which Javascript library would you recommend for my needs?

Depending on your project, you could receive a lot of different answers to this question. A web developer should be able to explain how they would use jQuery to create code-light applications or React to develop user interfaces for single-page applications. Showing examples of where they have used these libraries in a professional capacity should be expected. If a web developer cannot recommend a library to achieve your goals, they might not be able to provide the service which would be perfect for your design needs.

7. How could asynchronous Javascript be used in this project?

Asynchronous Javascript is used for interactive aspects of a webpage that do not cause it to refresh. Discuss what elements you want to be included with your development project and the top front-end developers will be able to identify how you can use asynchronous Javascript to create an interactive feel.

8. When would you suggest using React instead of front end development?

If you need an attractive UI for a single-page application, a front-end developer should be ready to use React.js. This library was built with creating attractive front pages, thanks to the following qualities:

  • Quick to load
  • Declarative
  • Component-based
  • Easily used for mobile browsers

9. How do you secure the front end?

Security is an afterthought for some, but it shouldn't be during the front-end development process. Front-end developers should be able to explain how they defend against common cyber-attacks on web applications. Common examples include clickjacking (an HTML exploit) and DOM-based cross-site scripting (XSS) attacks. Ideally, your developer should also understand how to defend the full-stack against common attacks and will explain how they have implemented secure code in the past.
