How To Find AngularJS Interview Questions [+With Example]

A great interview can help you to get insights into the developer's expertise and experience. If you plan to interview an AngularJs developer, you must require some research guide or gathered information. A researched material would help you examine the candidate's skills, knowledge, and experiences. With that in mind, we have prepared a step-by-step guide to help you find the AngularJs interview questions you should probably ask. Look at this informative guide to learn how to determine the interview questions before interviewing the candidate.

Principle Of Writing An Angular Developer Interview Questions

The mentioned guidelines will help the AngularJS development company to develop a list of interview questions-

The list of questions should be clear and concise. Try not to ask more than one question at a time.

Ask questions that elicit the most extended answers from the candidate. Avoid asking questions that can answer in one or two lines.

Do your analysis correctly, don't ask the candidate to do research or something. 

Do not ask for opinions on the community in which they work, like- "How does the team manage it?" You will not get an optimistic answer. 

5. Feel free to ask embarrassing questions to identify Angular developer skills and the ability to think. 

6. Ask them about their experiences and what they have learned from their experiences.

Types of Angular developer Interview Questions

Here is the list of Angular developer interview questions that help you determine when and what to ask-

A. Credential verification questions

This type of question includes information like "What is your percentage in 10+2?" and "How many years have you worked with XYZ company?" Here you verified the information mentioned in their resume. It would help in verifying their credentials and verified information.

B. Opinion questions

These questions are being asked when you need to understand their inner self. Questions like "What would you do in this situation?" and "Tell me about your weaknesses" helps in analyzing how they would respond in such situations. 

C. Behavioral questions

This question includes "Give an example of how you did that?" and "What process do you follow to determine better results?" It helps in measuring their past behaviors and their optimistic behavior.

D. Competency questions

The questions like "How can you determine the leadership skills?" or "What steps you'll take to finish this task" are being asked to examine their past behaviors with specific required competencies.

E. Nonsense questions

The questions like "What kind of cinema do you like?" and "Do you love exploring food?" ask to find out if they are capable of original thought. This question is asked to test your ability to think on your feet.

How to Write Interview Questions?

1. Identify and summarise the study's main research questions. Describe the broad knowledge domains that are needed to respond to these issues.

2. Create questions inside these critical categories, tailoring them to different types of respondents. Utilizing their knowledge and expertise is the main objective here.

3. Modify the interview's language based on the respondent (child, professional, etc.).

4. Be careful how you phrase your questions to encourage respondents to provide as detailed and accurate answers as possible.

5. Focus on "how" questions rather than "why" to know their background stories. "What inspired you to do this?"

6. Create probes to elicit more extensive and in-depth answers to important questions.

7. Start the interview with a "warm-up" question that will allow the respondent to answer more fully and readily (though not too long).

8. Consider the interview's logical flow. What subjects need to ask first? Adjust the asking pattern accordingly.

9. You should ask difficult and tricky questions at the end of the interview.

Top 3 AngularJS Interview Questions and Answers

1. What are the steps to test an AngularJS filter?

Inject the module with a filter.

Include mocks which the filter relies upon.

Add the filter using $filter('yourFilterName').

Insert your expectations.

2. Where should we implement the DOM manipulation in AngularJS?

DOM Manipulations don't exist in controllers, services, or anywhere. It only existed in directives.

3. What are Directives?

An AngularJS framework directive is a marker on a DOM element (such as an attribute, element name, comment, or CSS class) that instructs the HTML compiler ($compile) to alter the DOM element and its descendants or to attach a specific function to the DOM element.

Summing up

We hope you like the article. Next time you interview an Angular developer, don't forget to look out for these tips to ask the best questions to them. Good luck :)

Top 10 Interview Questions for Angular Best Practices

Do you want to ace an interview with full marks? Don't have time to read everything about Angular? Read our top interview questions for Angular best practices, which will help you answer theoretical and Angular practical questions. 

What is Angular?

Angular is a JavaScript-based front-end web application framework designed to create applications to make them easy to test, maintain and extend. It uses HTML as the view layer and JavaScript as the application logic layer.

1. What are the technologies used in Angular?

Angular is a web application framework created and maintained by Google. It is used to develop applications that run on the client-side, server-side, or both.

Angular is built on top of TypeScript, a superset of JavaScript that adds type checking and static type definitions for variables and expressions. Angular also uses the Web Components standard to build reusable UI components.

Some of the other technologies used in Angular are TypeScript, RxJS, Webpack, ES6+, Webpack Dev Server. 

2. What is Angular mainly used for?

Angular was first released in 2016, and it has been gaining popularity ever since. The framework allows developers to build single-page applications with the help of JavaScript and HTML. It also provides a set of tools that can be used for building reusable components, routing, animations, data binding, directives, and more. It is mainly used in different fields such as web development, mobile development, or even machine learning.

3. What is the difference between Angular and AngularJS?

Angular is a JavaScript-based framework that allows web developers to build mobile and desktop applications. AngularJS is a subset of Angular that focuses on client-side application development.

The main difference between Angular and AngularJS is that Angular uses TypeScript while AngularJS uses JavaScript. This means that the code written in TypeScript will be compiled into JavaScript automatically by the compiler, which helps improve the code's performance and maintainability.

4. What do you mean by data binding in Angular?

Data binding is a process by which data changes in the model are automatically updated in the view. The term "data binding" comes from its first use, when it was used to bind values to DOM elements. Still, we now use it more generally to describe any automatic updating mechanism that uses data from one component to update another.

Data binding can be implemented through events or expressions. In Angular, we use expressions for data binding because they are concise and provide flexibility over events.

5. What is the scope in Angular?

A scope is a powerful tool of Angular. It allows developers to define the visibility of a component in a particular view. A scope has two main components - controllers and directives. Controllers are the objects that define how your application should behave, while directives are the objects that dictate how your application should look like.

6. What are directives in Angular?

Angular directives are one of the most important concepts in Angular. They are used to extend the functionality of Angular applications and enhance their capabilities. Directives allow us to create custom components that can be reused in our application. They also provide a way to reuse code across different parts of our application by encapsulating it within a directive. Directives are not just limited to Angular, and they can be used in any web-based framework like React or Vue. 

7. What is server-side rendering in Angular?

Server-side rendering is a technique that renders the HTML of a web application on the server and then reverts it back to the client. This enables web applications to be delivered faster.

Server-side rendering is an important technique for making Angular apps more performant and scalable. Angular apps typically have a lot of UI components, which are rendered on the client-side. These components are not rendered with server-side rendering until the user requests them. This makes the app load faster and can be scaled better because it won't have an extra load on the server when it's not needed.

Server-side rendering is used in conjunction with other techniques such as lazy loading, service workers, and prerendering to make your Angular app much faster than before.

8. What is an Angular Router?

Angular Router is an AngularJS library that provides a routing system for the application. It allows us to promptly and easily create navigation between views or pages in our AngularJS app.

Angular Router is commonly used by UI developers who have built complex applications with multiple screens, including single-page apps (SPA) or hybrid mobile apps with web views.

9. What is the digest cycle process in Angular?

The digest cycle process in Angular is when a component or module needs to update itself and its dependencies after changes have been made to its code. The process starts with Angular's change detection mechanism that triggers updating any component or module that has changed since the last time it was updated.

The digest cycle process in Angular also involves updating any dependent modules and components triggered by change detection and updating any registered services and observables.  

Wrap Up 

So, these were the top Angular-based interview questions you should learn for Angular best practices and ace your interview with full marks. However, these questions are limited to interviews and help you deal with practical problems while developing apps.

If these source codes do not exist at runtime and we try to use them, then it will break without warning. Ambient declarations files are like docs file. If the source changes, the docs need to be kept updated also. If the ambient declaration file is not updated, then we will get compiler errors. The Ambient declarations allow us to safely and easily use existing popular JavaScript libraries like jquery, angularjs, nodejs, etc. 35. What is a TypeScript Map file? TypeScript Map file is a source map file which holds information about our original files. .map files are source map files that let tools map between the emitted JavaScript code and the TypeScript source files that created it.
