Angular Interview Questions For Experienced

Experienced angular interview questions probe the candidate's in-depth understanding of Angular's architecture, design patterns, performance optimization, and real-world application development. These questions assess the candidate's ability to build scalable, maintainable, and efficient Angular applications. By evaluating the candidate's knowledge of advanced concepts like dependency injection, change detection, observables, and reactive programming, the interview panel can gauge the candidate's expertise in leveraging Angular's capabilities to create robust and performant solutions that meet complex business requirements.

1 - Explain Angular's dependency injection mechanism. Dependency injection is a design pattern that manages dependencies between components by providing them at runtime. Angular uses a tree shaking technique to optimize injection and reduce bundle size.

2) Describe Angular's change detection strategy. Angular's change detection mechanism tracks changes in the application state and updates the UI accordingly. It uses a zone.js library to intercept asynchronous events and trigger change detection.

3) Explain the difference between a component and a directive. Components are reusable, encapsulated units that include HTML, CSS, and behavior, while directives modify the behavior or appearance of existing HTML elements.

4) Discuss Angular's routing mechanism. Angular's routing system allows for navigation between different views within the application. It supports dynamic routing, lazy loading, and URL handling.

5) Explain the purpose of the `HttpClient` service. The `HttpClient` service is responsible for making network requests and handling HTTP responses. It provides a consistent API for HTTP communication and integrates with change detection for automatic updates.

6) Describe how to implement data binding in Angular. Data binding allows for the synchronization of data between the TypeScript application logic and the HTML template. Angular supports two way binding, one way binding, and event binding.

7) Explain the difference between synchronous and asynchronous operations in Angular. Synchronous operations run immediately, while asynchronous operations are scheduled to run later. Asynchronous operations allow for improved responsiveness and avoid blocking the UI thread.

8) Discuss the benefits of using Angular CLI. Angular CLI (Command Line Interface) is a tool that simplifies the development and maintenance of Angular applications by providing commands for scaffolding, testing, building, and deployment.

9) Explain how to implement unit testing in Angular. Unit testing in Angular involves creating test cases that verify the behavior of individual components or modules. Angular provides a built in testing framework that automates the setup, execution, and assertion of tests.

10) Discuss the use of Redux with Angular. Redux is a state management library that helps maintain application state in a centralized and predictable manner. Integrating Redux with Angular allows for efficient state management and facilitates the development of complex and scalable applications.

11 - Explain the concept of lazy loading in Angular. Lazy loading is a technique that defers the loading of certain modules or components until they are actually needed, resulting in improved performance and reduced initial load time.

12) Describe how to implement server side rendering with Angular. Server side rendering (SSR) allows for the initial rendering of an Angular application on the server, improving page load times and SEO visibility.

13) Discuss the best practices for performance optimization in Angular. Performance optimizations in Angular include code splitting, tree shaking, lazy loading, change detection optimizations, and minimizing DOM operations.

14) Explain how to implement security measures in Angular. Security in Angular involves measures such as sanitizing user input, preventing cross site scripting (XSS) attacks, and implementing authentication and authorization mechanisms.

15) Discuss the future of Angular and its potential impact on web development. Angular continues to evolve with new features and performance improvements, making it a promising framework for building modern and scalable web applications.
