5 Vue.js interview questions and answers related to terms and definitions
Take a look at the five Vue.js interview questions below and use the answers as a guide when assessing your developers’ responses.
1. How is one-way data flow different from two-way data binding?
Can your applicants explain that the application’s UI isn’t updated automatically for one-way data flow?
Developers have to write custom code to ensure it updates once they make a change. In contrast to one-way data flow, the application’s UI is updated automatically for two-way data binding.
Applicants may explain that developers use the v-bind directive for one-way data flow and the v-model directive for two-way data binding.
2. Outline the 8 lifecycle hooks for Vue.js instances.
The eight lifecycle hooks that applicants may mention when responding to this question are:
- beforeCreate event: An initial event developers use to complete actions before they add a component to the DOM
- created event: An event developers use to run code once they have created an instance
- beforeMount event: An event developers use to execute before rendering
- mounted event: A commonly used event in which developers can access components, the rendered DOM, and templates
- beforeUpdate event: An event developers use before executing data changes on components
- updated event: An event developers use to execute data changes on components and re-render the DOM
- beforeDestroy event: An event developers use before they tear down an instance
- destroyed event: A final event developers use to perform clean-ups
3. Give an example of a system modifier key that Vue.js supports.
Developers may explain that system modifier keys trigger event listeners and provide a few examples of system modifier keys that support Vue.js. Some of the main keys include:
4. Explain what Vue.js component props are.
Your applicants should be familiar with Vue.js component props. Do they know that component props are attributes that they can register on components? Can they explain that they can use component props to pass data down to child components?
5. Explain what the <slot> element is in Vue.js.
Developers familiar with Vue.js should understand that <slot> is an element that programmers use as a content distribution outlet.

5 Vue.js interview questions and answers related to processes
Here are five critical Vue.js interview questions related to processes, along with sample answers you can use to assess your interviewees’ skills and knowledge.
1. Name four approaches for installing Vue.js to complete your project.
Are your applicants familiar with the four main approaches for installing Vue.js to complete a project? These are:
- Using the Node Package Manager (or NPM)
- Using Bower
- Using the Vue command-line interface (or vue CLI)
- Using the CDN with a <script> tag within an HTML file
2. How would you create filters in Vue.js?
Applicants may split their answer into two parts when responding to this question, because there are two options to create filters in Vue.js.
Developers may define local filters in the component’s options to create local filters. This means each filter is allocated to the specified component.
To create global filters, developers may define them globally before creating the instance. This means filters are allocated to every component the Vue instance contains.
3. Which command would you use to deploy a Vue.js application?
Your candidates should know that they can use the following commands to deploy a Vue.js application:
- To create a project: vue init webpack myproject
- To run a project: npm run build
4. How would you handle errors in Vue.js?
Can your developers explain that an error handling mechanism can help programmers avoid application breakages even if an unhandled exception occurs? Do they know that they can use error handling mechanisms to log errors to a server to determine the cause?
5. In which situation is local registration required in Vue.js?
Applicants should know that programmers use local registration when global registration is not a good option. For instance, global registration doesn’t allow built systems to remove components that aren’t being used. It’s better to use local registration in Vue.js To avoid this drawback.
5 tips for using Vue.js interview questions during an interview
Check out our list of tips below to use Vue.js interview questions to assess candidates.
1. Invite applicants to complete a skills assessment before the interview
Tip number one: Integrate skills testing into the hiring process.
You can build a single skills assessment that features up to five skills tests relevant to the role, including a Vue.js test.
It’s best to invite applicants to take a skills assessment early in the recruitment process, which will help you decide which candidates you should invite to an interview.
2. Tell candidates more about the open role before asking Vue.js interview questions
Our second tip: Never just plunge directly into the interview.
Inform your applicants about your role and your organization and ask them to introduce themselves. Let candidates know more about the Vue.js developer role before asking them any Vue.js interview questions to give them more context and help them feel more at ease.
3. Begin with general Vue.js interview questions
Tip number three: Never go straight to expert-level Vue.js interview questions or questions related to processes.
Instead, start by getting a sense of your applicant’s general Vue.js knowledge by asking them a few general Vue.js interview questions at the start of the interview.
4. Take notes during the interview
Our fourth tip: It’s a good idea to take notes during the interview and document your applicants’ responses.
Taking notes (and eventually using a scoring sheet) means that you can compare your findings with other team members and senior engineering managers to make a collaborative hiring decision.
However, make sure to tell your applicants you’re going to take notes at the start of the interview.
5. Offer feedback to developers you didn’t choose
And our final tip: Give feedback to the developers you didn’t choose.
You’ll have gathered plenty of data on your applicants at this stage, so provide them with meaningful feedback to enhance the candidate experience and your company’s reputation.
