Highlight the benefits of MVVM, such as improved testability, maintainability, and separation of concerns. Mention how it's implemented in Angular using components and services.
Example answer:
"MVVM is an architectural pattern designed to separate the UI, or View, from the underlying data and logic. The ViewModel acts as an intermediary, exposing data required by the View and handling user interactions. In a recent project, using MVVM allowed us to easily unit test the ViewModel logic independent of the UI, speeding up our development process. Ultimately, understanding MVVM helps build testable, maintainable Angular applications."
2. What is a Bootstrapping Module?
Why you might get asked this:
This question aims to evaluate your understanding of Angular's application initialization process. They want to know if you understand the role of the root module in starting the application, a critical component in angular interview questions for experienced.
How to answer:
Explain that the bootstrapping module is the root module (typically AppModule) that Angular uses to launch the application. Describe how it declares the application's components, services, and other dependencies. Highlight its role in configuring the application and initiating the rendering process.
Example answer:
"The bootstrapping module, usually AppModule, is the entry point that Angular uses to kick off the entire application. It's where we declare all the necessary components, services, and modules that our app relies on. On a past project, we made sure all feature modules were imported correctly in the AppModule to avoid runtime errors. This ensures Angular knows where to start rendering the application and how everything fits together."
3. What is Change Detection in Angular?
Why you might get asked this:
This question assesses your understanding of how Angular keeps the UI in sync with the underlying data. Understanding change detection is fundamental for efficient Angular development, a common theme in angular interview questions for experienced.
How to answer:
Explain that change detection is the mechanism Angular uses to automatically update the view (DOM) when the component's data changes. Describe how Angular tracks changes using zones and how it triggers change detection cycles. Discuss the different change detection strategies (Default and OnPush) and their implications for performance.
Example answer:
"Change detection in Angular is the process that automatically updates the view when the data in our components changes. Angular uses Zones to be notified of asynchronous operations like HTTP requests or user events, triggering a change detection cycle. In a performance-critical application, we used the OnPush strategy to limit change detection to components where input properties actually changed. Knowing how change detection works is crucial for building efficient Angular apps."
4. What is the Purpose of Angular CLI?
Why you might get asked this:
The interviewer wants to know if you're familiar with the standard tooling used in Angular development and if you appreciate its role in streamlining development workflows. This is always touched upon in angular interview questions for experienced.

Example answer:
"TypeScript is fundamental to Angular because it provides static typing, which is a huge advantage for large Angular projects. It allows us to catch errors during development rather than at runtime, and it improves code maintainability with features like interfaces and classes. Switching to TypeScript on one project allowed us to refactor confidently, knowing the compiler would catch any type-related issues. For building robust Angular apps, TypeScript is essential."
6. What are Angular Components?
Why you might get asked this:
This question aims to evaluate your understanding of the fundamental building blocks of an Angular application. It's a basic but crucial element in angular interview questions for experienced.
How to answer:
Explain that components are the core building blocks of an Angular application, responsible for rendering a specific part of the user interface. Describe that each component consists of a template (HTML), a class (TypeScript), and metadata that defines its behavior and properties. Highlight how components promote reusability and modularity.
Example answer:
"Angular components are the fundamental building blocks of any Angular app. Each component encapsulates a specific part of the UI, including its HTML template, the TypeScript class that controls its logic, and metadata that defines its properties. By breaking down the UI into reusable components, we can build complex applications in a manageable and maintainable way."
7. What is the Difference Between ngOnInit and Constructor?
Why you might get asked this:
This question assesses your understanding of the component lifecycle and when to use each lifecycle hook appropriately. This comes up a lot in angular interview questions for experienced.
How to answer:
Explain that the constructor is used for dependency injection and simple initialization tasks. ngOnInit is a lifecycle hook called after the component is initialized, typically used to fetch data, set up subscriptions, or perform other initialization tasks that depend on the component's input properties.
Example answer:
"The constructor is primarily for injecting dependencies into the component, whereas ngOnInit is an Angular lifecycle hook that's called after Angular has initialized the component's input properties. We use the constructor for setting up our dependencies and ngOnInit to perform actions like fetching data from an API. Understanding this difference helps us manage component initialization effectively."
8. Explain the Role of zone.js in Angular
Why you might get asked this:
This question assesses your understanding of how Angular detects changes in the application state and triggers change detection cycles. You would want to thoroughly look this over for angular interview questions for experienced.
How to answer:
Explain that zone.js is a library that Monkey-patches standard browser APIs to intercept asynchronous operations, such as HTTP requests, timers, and event listeners. Describe how Angular uses zone.js to be notified of these events and trigger change detection cycles to update the view.
Example answer:
"Zone.js is crucial for Angular's change detection because it monkey-patches standard browser APIs, allowing Angular to be aware of asynchronous operations like HTTP requests or user events. When one of these operations completes, Zone.js notifies Angular, which then triggers a change detection cycle to update the UI. This ensures our views stay in sync with our data, even when changes are triggered asynchronously."
9. What are Angular Pipes?
Why you might get asked this:
This question aims to evaluate your ability to transform data in templates for display purposes. This is relevant for angular interview questions for experienced.
How to answer:

Example answer:
"Angular pipes are a convenient way to transform data directly in our templates. We can use built-in pipes like date or uppercase to format data, or create custom pipes for specific transformation needs. One time, we created a custom pipe to format phone numbers in a specific format, making our templates cleaner and more readable. Pipes help us keep our components focused on logic and our templates focused on presentation."
10. How to Create a Custom Pipe?
Why you might get asked this:
This question assesses your ability to extend Angular's functionality by creating reusable data transformation components. Be prepared for this when tackling angular interview questions for experienced.
How to answer:
Explain the steps involved in creating a custom pipe: create a class that implements the PipeTransform interface, use the @Pipe decorator to register the pipe, and implement the transform method to perform the data transformation. Provide an example of a custom pipe and how to use it in a template.
Example answer:
"To create a custom pipe in Angular, we first create a class that implements the PipeTransform interface. We then use the @Pipe decorator to give it a name and register it with Angular. The core of the pipe is the transform method, where we implement the data transformation logic. For example, we once created a custom pipe to truncate long strings and add an ellipsis, which made our UI much cleaner. Custom pipes allow us to encapsulate and reuse data transformations throughout our application."
11. What are Angular Directives?
Why you might get asked this:
This question aims to evaluate your understanding of how to extend HTML with custom behavior and manipulate the DOM. Key to remember when preparing for angular interview questions for experienced.
How to answer:
Explain that directives are used to add custom behavior to HTML elements in Angular templates. Describe the different types of directives (component directives, attribute directives, and structural directives) and provide examples of how each type is used to modify the DOM.
Example answer:
"Angular directives are powerful tools that allow us to extend HTML with custom behavior. We have three main types: component directives, which are components with a template; attribute directives, which change the appearance or behavior of an element; and structural directives, like ngIf and ngFor, which modify the DOM structure. I once built a custom attribute directive that highlighted certain elements based on a condition, providing a dynamic way to emphasize key information in the UI. Directives give us a lot of flexibility in Angular."
12. What is AOT Compilation?
Why you might get asked this:
This question assesses your knowledge of performance optimization techniques in Angular applications. AOT is a crucial aspect of Angular performance. Be sure to study this well for angular interview questions for experienced.
How to answer:
Explain that Ahead-of-Time (AOT) compilation is a process that compiles Angular templates and components into JavaScript at build time, rather than at runtime in the browser. Describe the benefits of AOT compilation, such as improved startup performance, reduced bundle size, and enhanced security.
Example answer:
"AOT compilation is where Angular compiles the application during the build process, before it even gets to the browser. This means the browser downloads pre-compiled code, which results in faster startup times and improved security. We saw a significant improvement in our application's initial load time after enabling AOT. It's a fundamental optimization technique for any production Angular app."
13. How Does Angular Handle Tree Shaking?
Why you might get asked this:
This question assesses your understanding of how to reduce the size of the final application bundle by removing unused code. Vital for optimal performance, a good understanding of this is needed for angular interview questions for experienced.
How to answer:
Explain that tree shaking is a process that removes unused code from the final application bundle. Describe how Angular uses tools like Webpack to analyze the application's dependencies and eliminate any code that is not actually used. Highlight the benefits of tree shaking, such as reduced bundle size and improved loading performance.
Example answer:
"Tree shaking is a build optimization technique that eliminates dead code from our final application bundle. Angular, with the help of tools like Webpack, analyzes our application's dependencies and removes any code that isn't actually used. This results in smaller bundle sizes, faster load times, and a better overall user experience. Tree shaking is essential for creating efficient Angular apps, especially for mobile users."
14. Explain the Concept of Single Page Applications (SPAs)
Why you might get asked this:
This question aims to evaluate your understanding of the architectural pattern underlying Angular applications. This is a concept you should know well for angular interview questions for experienced.

Explain that Single Page Applications (SPAs) are web applications that load a single HTML page and dynamically update the content in response to user interactions, without requiring full page reloads. Describe the benefits of SPAs, such as improved user experience, faster loading times, and reduced server load.
Example answer:
"Single Page Applications, or SPAs, are web applications that load a single HTML page and then dynamically update the content using JavaScript. This provides a more responsive and seamless user experience compared to traditional multi-page applications. By minimizing full page reloads, SPAs can significantly improve performance and reduce server load."
15. What are Interceptors in Angular?
Why you might get asked this:
This question assesses your ability to modify HTTP requests and responses for tasks like authentication, logging, or caching. Interceptors are a key architectural component, often probed in angular interview questions for experienced.

Example answer:
"Angular modules are used to organize our application into cohesive blocks of functionality. They group related components, directives, pipes, and services, providing encapsulation and promoting code reusability. The root module, typically AppModule, is the entry point that bootstraps the entire application. Modules help us manage complexity and maintain a clear structure as our application grows."
20. What is the Purpose of FormsModule and ReactiveFormsModule?
Why you might get asked this:
This question assesses your understanding of the two main approaches to building forms in Angular applications. Forms are such a common and frequent feature in development, so it should be reviewd for angular interview questions for experienced.
How to answer:
Explain that FormsModule is used for template-driven forms, where the form structure and validation logic are defined in the HTML template. Describe that ReactiveFormsModule is used for reactive forms, where the form structure and validation logic are defined programmatically in the component class. Highlight the advantages and disadvantages of each approach.
Example answer:
"FormsModule and ReactiveFormsModule offer two different ways to handle forms in Angular. FormsModule is great for simpler forms where you define the form structure and validation directly in the template. ReactiveFormsModule, on the other hand, is ideal for more complex forms where you need more programmatic control over the form's structure and validation logic. I tend to use ReactiveFormsModule when I need to implement custom validation or dynamic form controls."
21. What are Angular Services?
Why you might get asked this:
This question aims to evaluate your understanding of how to share data and logic between components in Angular applications. Services are a core concept. You should be familiar for angular interview questions for experienced.

"Angular services are used to share data and functionality between components. They are typically used to encapsulate business logic, interact with APIs, or manage application state. By using services and dependency injection, we can create a more modular and testable application. For instance, we create an authentication service to handle user login and manage user sessions."
22. Explain the Difference Between One-Way and Two-Way Binding
Why you might get asked this:
This question assesses your understanding of how data flows between components and templates in Angular applications. Data binding is such an important concept. Look over it when preparing for angular interview questions for experienced.
How to answer:
Explain that one-way binding updates the view (DOM) when the component's data changes, but does not update the component's data when the view changes. Describe that two-way binding updates both the view and the component's data when either changes. Provide examples of how each type of binding is used in Angular templates.
Example answer:
"One-way binding means data flows in one direction, either from the component to the view or vice versa. Two-way binding, on the other hand, keeps the component and the view synchronized, so any changes in the view are immediately reflected in the component, and vice versa. We often use two-way binding with form inputs so that user input is immediately reflected in the component's data."
23. How to Manage Version Control in Angular Projects?
