Interviews allow the interviewer to collect relevant information from the interviewee. This information can include details about qualifications, experiences, skills, and suitability for the position.

In a technical interview for a position related to Angular framework, the candidates need to prepare for the understanding of the framework, it will help them perform well during the interview.

1. What is Angular framework? 

To warm-up, the interview usually asks about the concept or overview information about the target technology. This question is common when starting an interview about Angular framework.

When encountering this question you can talk about the notion of this framework, which is presented on the Angular documentation page ⁽¹⁾:

"Angular is a development platform, built on TypeScript.

As a platform, Angular includes:

• • • • • A component-based framework for building scalable web applications
        • A collection of well-integrated libraries that cover a wide variety of features, including routing, forms management, client-server communication, and more
        • A suite of developer tools to help you develop, build, test, and update your code"

Or, it would be better if you present it according to your understanding, such as:

Angular is an open source framework based on TypeScript that makes it easy to build web, mobile, and desktop applications. The key features of this framework include declarative templates, dependency injection feature, end to end tools that make application development easy. Angular is currently maintained and developed by Google.

Success with the first question will help you be more confident in the next questions. Besides, the interviewer will be more open during the next interview process because of your preparedness.

2. What is the Typescript?

Interviewers often tend to ask about small ideas in your previous answer, so you can rely on that to prepare for the next few questions. This question is one such question.

Typescript is the main factor of Angular, so understanding it is important. You can demonstrate your understanding by providing more information beside the overview, for example comparing it with Angular JS:

Typescript is a superset of JavaScript, a compiler is needed to compile the Typescript code into JS so that the browser (or runtime environment) can understand and process it.

JavaScript is a Dynamic language, no need to declare data types while Typescript needs to declare data type

3. What does angular application have?

With a question like this, the interviewer wants to know if you have participated in any real projects and if you recognize the important components of the framework.

You can list these main parts of an Angular application:

An application is a collection of components and a few services that provide functionality on those components:

• • • • • Angular Application = Component + Component + Component … + services
        • Component = Template + Class + Metadata

4. What are the outstanding features of Angular?

This is an easy question to get points. You can easily search for information online, memorize it and wait until you are asked in the interview to answer it confidently. 

These are some outstanding features of Angular framework:

• • • • Two-Way Data Binding mechanism
      • Supports powerful Routing mechanism
      • HTML extension
      • Modular design
      • Support working with Backend system
      • Large support community

You will also receive higher recognition when you prepare an explanation along with the above main ideas.

5. What types of bindings does Angular have?

After these general questions, the interviewer will start asking questions that go deeper into the framework's features.

You can list types of binding that Angular support and tell the interview purpose of each of them:

• • • • Data binding (Interpolation): allows you to embed dynamic values directly into your HTML templates.
      • Property binding: allows to set values for properties of HTML elements or directives.
      • Event binding: allows to respond to user interactions (such as clicks, mouse movements, or keyboard events) by invoking methods in your component.
      • Two-way binding: Two-way binding combines property binding and event binding. It allows you to synchronize data between a component property and an input element (like an input field or a checkbox).
      • Class and style binding: add or remove CSS class names/styles from an element’s class/style attribute based on conditions.

 

Above are overview questions commonly used in an Angular framework interview.

Hopefully after this post, you will understand how the interviewer asks questions and have suggested questions for your preparation before interviews.

In the next post, I will suggest some more detailed questions, so you can pass the interview with a good outcome.
