Q:

What are your favorite features of HTML5, and how have you implemented them in your front end development projects?

A:

Front end developers spend a lot of time using HTML5 when they’re putting together web designs and have access to a wide range of features that can save development time and improve the end product. What to look for in an answer:

  • In-depth knowledge of HTML5 features
  • Clear explanation of how the applicant used HTML5 in past projects
  • Creative usage of HTML5 features
Example:

“I enjoy the way HTML5 handles multimedia support compared to previous versions. I use this feature to develop a front end design that incorporates videos and audio as an essential part of the experience without worrying about it not loading properly or breaking the page.”

Q:

How do you structure your CSS and JavaScript to make it easier for other developers to work with?

A:

Front end developers often work on code created by previous employees or operate as part of a team. This question gives you an idea of whether they can create websites or web applications that will be understandable by other employees. What to look for in an answer:

  • Experience with code organization and code commenting
  • First-hand knowledge of what happens when code isn’t commented appropriately
  • A willingness to make things easier on the other development teams
Example:

Q:

Can you explain the concept of a CSS float and provide an example of its usage?

A:

This technical question quizzes the applicant on their understanding of a common CSS element. This basic question is a good way to screen the interviewee and ensure that they’re more than acquainted with CSS. What to look for in an answer:

  • A concrete definition of CSS floats
  • Examples of how the applicant uses this element in their code
  • Confidence in explaining this technical concept to any audience
Example:

“A CSS float tells the browser to put a particular element to the right side or the left side of the container. I use floats when I’m developing a page that dynamically resizes based on the user resolution.”

Q:

What’s your process for addressing browser-specific rendering problems? Do you find that a certain browser is more challenging to work with than others?

A:

Front end developers have to introduce browser-specific hacks into web applications and pages due to the way each application handles rendering. This common process should be a familiar one for the people you interview. What to look for in an answer:

  • Examples of browser-specific workarounds
  • Understanding of how browsers render apps and pages
  • Knowledge of troubleshooting browser-specific problems
Example:

“I often have to change the DIV positions on web pages for Microsoft Edge. This browser is the most problematic one for me, as I don’t run into issues on Chrome or Firefox nearly as often.”

Q:

Q:

What are your favorite types of front end development projects to work on? What do you like about them?

  • A strong opinion on their favorite types of development
  • Enthusiasm for the project types they describe
  • Examples of their favorite front end development projects
Example:

Q:

What do you think are the most important aesthetic aspects of a webpage and why?

A:

Front end developers need to be able to balance creative design with the technical skill involved in creating a website. They have to think about what makes a website most appealing to visitors while still maintaining functionality. Front end developers can have different opinions on how to create an impactful design, but they should be able to explain their creative process and the reasoning behind their aesthetic choices. Interviewers can use this question to select candidates with good artistic sensibilities. Some of the elements of an excellent answer may include:

  • Example of webpage elements
  • Discussion of personal style choices
  • User-focused mindset
Here is one example of a successful answer:
Example:

"I like to use minimalist design concepts in my work. Although all elements of a webpage work together to capture a user's attention, I think the initial header and landing page design are especially important. Using mild colors and readable fonts helps emphasize the content of the page without distracting the webpage visitor."
