Prepare for your Frontend Engineer interview. Understand the required skills and qualifications, anticipate the questions you may be asked, and study well-prepared answers using our sample responses.
This question can help the interviewer get a sense of your expertise and experience with frontend frameworks. Your answer should include a list of your favorite frameworks, along with an explanation of why you prefer them over others.
Answer: “My favorite frontend frameworks are React and Angular. I find React to be an excellent choice for building highly interactive web applications due to its component-based architecture and declarative style. It also has an extensive ecosystem of libraries and tools that make it easy to implement complex features. In contrast, Angular is a full-stack framework that provides a robust platform for building robust and scalable applications. It also provides built-in support for TypeScript, which makes it easier to write maintainable code.”

This allows me to use the right tool for each job, which makes it easier to maintain the site later on. For example, if I need to add some animation to a page, I’ll use CSS3 for that task. If I need to create a more complex interaction, like a dropdown menu, I’ll use JavaScript.”
This question can help the interviewer get a sense of your experience with JavaScript libraries. JS libraries are collections of code that allow developers to quickly and easily create applications. They are an essential part of frontend engineering, so it’s important to have experience using them.
Answer: “I have extensive experience working with JS libraries. I have used a variety of libraries including jQuery, AngularJS, React, Vue.js, and Bootstrap. I am familiar with the benefits and drawbacks of each library and can apply that knowledge to create efficient and effective solutions.”

Answer: “Client-side and server-side scripting are two different types of programming that serve different purposes. Client-side scripting is used to create interactive web pages that can be viewed in a browser. This type of scripting allows users to interact with the page by changing its appearance, behavior, or content. For example, when you hover over an element on a page, it may change color or move around. This is because the code behind those elements is being executed on the client-side.”
