Angular developer interview questions: the 10 most popular ones
1. What is Angular and how does it differ from AngularJS?
Angular represents a complete paradigm shift from AngularJS. While AngularJS was a JavaScript-based MVC framework, Angular is a TypeScript-based platform and framework for building scalable web applications. Key differences include:
- Architecture: Component-based (Angular) vs MVC (AngularJS)
- Language: TypeScript vs JavaScript
- Mobile Support: Built-in vs Limited
- Performance: Improved with Ivy renderer vs Slower digest cycle
- CLI: Advanced CLI tools vs No CLI
- Dependencies: Modern dependency injection vs Limited DI
Summary
- Complete rewrite in TypeScript
- Component-based architecture
- Better performance and mobile support
- Modern tooling and CLI
2. Explain Components in Angular
Components are the fundamental building blocks of Angular applications. Each component consists of:
- Template (HTML): Defines the view and user interface
- Class (TypeScript): Contains the component's logic and data
- Metadata (@Component decorator): Provides additional information about the component
- Styles: Component-specific CSS
Components follow a hierarchical structure where parent components can pass data to child components using @Input(). Child components can emit events to parents using @Output(). And components can be nested to create complex UIs.
Summary
- Basic building blocks of Angular apps
- Contains template, class, metadata
- Hierarchical structur
- Encapsulated functionality
3. What is dependency injection in Angular?
Dependency Injection (DI) in Angular is a design pattern and mechanism where classes receive their dependencies from an external source rather than creating them internally. Angular's DI system consists of:
- Injector: The service that holds dependency instances
- Provider: Tells the injector how to create the dependency
- Dependency: The service/value being injected
- Consumer: The class that needs the dependency
Summary
- Design pattern for managing dependencies
- Angular handles dependency creation and lifecycle
- Makes code more testable and maintainable
4. Describe the difference between Promises and Observables
Promises and Observables handle asynchronous operations differently:
Promises |
- Handle single events
- Cannot be canceled
- Always asynchronous
- Not lazy - execute immediately when created
- Cannot retry on error
|
Observables |
- Can handle multiple events over time
- Support cancellation through unsubscribe
- Can be synchronous or asynchronous
- Lazy - only execute when subscribed to
- Support retry and error handling operators
- Offer powerful operators (map, filter, merge, etc.)
- Enable complex data transformations
|
5. What are Angular Modules and why are they important?
Angular Modules (NgModules) are containers that group related code into functional sets. They consist of: Declarations (components, directives, pipes), Imports (other modules needed), Exports (declarations available to other modules), Providers (services) and Bootstrap (root component).
Key aspects:
- Every Angular app has at least one module (root module)
- Modules can be eagerly or lazily loaded
- Feature modules organize code by functionality
- Shared modules contain reusable components
- Routing modules manage navigation
Summary
- Organizational units for related code
- Enable lazy loading for better performance
- Manage component and service boundaries
- Essential for scalable application architecture
6. Explain Angular's change detection strategy
Change detection determines how Angular checks for data changes and updates the DOM. There are two main strategies: Default and OnPush.
Default |
- Checks all components on every change
- More predictable but less performant
- Runs after every event that can change data
|
OnPush |
- Only checks component on specific triggers
- More performant but requires careful implementation
- Triggers include: Input reference changes, event emissions, async pipe updates, and manual detection
|
7. What are Angular Services and when should you use them?
Angular services are singleton objects that provide shared functionality such as: data sharing between components, business logic implementation, external API communication, state management and utility functions.
Key characteristics:
- Injectable through dependency injection
- Singleton by default within their injection scope
- Can be provided at different levels
- Support inheritance and composition
- Enable separation of concerns
8. How do you handle routing in Angular?
Angular Router enables navigation between views:
Key features:
- Path configuration with components
- Route parameters and query strings
- Child routes for nested views
- Route guards for access control
- Lazy loading for better performance
- Navigation events for tracking
Common patterns:
- Using RouterLink directives
- Programmatic navigation
- Route resolvers for data
- Location strategies
- Custom route reuse strategies
9. What are Angular Directives and their types?
Angular Directives are markers that tell Angular to modify the DOM or element behavior.
There are 3 types:
Components |
- Directives with templates
- Most common type
- Have their own selector
|
Structural Directives |
- Modify DOM layout
- Examples: *ngIf, *ngFor, *ngSwitch
- Can create/destroy elements
|
Attribute Directives |
- Change appearance/behavior
- Examples: ngClass, ngStyle
|
10. How do you optimize Angular applications for performance?
Performance optimization involves multiple strategies:
Build-time optimization |
- Ahead-of-Time compilation
- Tree shaking unused code
- Production mode builds
- Code splitting and lazy loading
|
Runtime optimization |
- OnPush change detection
- Pure pipes
- TrackBy for *ngFor
- Unsubscribing from Observables
|
Loading optimization |
- Preloading strategies
- Resource prioritization
- Caching strategies
- Server-side rendering
|

How much does it cost to hire Angular developers?
Based on developer's location
The cost of hiring Angular developers varies significantly by region due to economic factors, market maturity, and technical education standards.
North America & Western Europe: Highest rates due to mature tech markets and high living costs. Here, you can expect developers with strong experience in enterprise applications, a good grasp of best practices, and cultural alignment with Western businesses. Same or similar time zones with US/EU clients is an added benefit. However, premium rates can strain budgets, there's high competition for talent, and turnover can be higher.
Eastern Europe & Latin America: Many developers have a strong theoretical foundation, problem-solving skills, and there's a growing Angular ecosystem. Some challenges include potential cultural differences, varying levels of English proficiency, and regional political instability.
Asia: These regions have large talent pools with strong technical education. While rates are very competitive, there are significant time zone differences with the West, and communication barriers may exist. Quality can vary, and projects may need more management oversight.
Here's an overview of estimated monthly salary for Angular developers in different regions:

Tip #2: Assess technical depth beyond surface-level skills
When you're interviewing candidates, don't just focus on their list of technical skills.
You want to hear their stories about solving real problems. Ask them about tough projects they've handled or complex performance issues they've fixed. Have them walk you through their thought process.
You'll learn more about a developer's true capabilities and how they'll handle problems on your team.
Tip #3: Look for full development lifecycle experience
Finally, you'll want someone who understands the bigger picture of software development. Look for developers who can tell you about working with different teams, reviewing others' code, and writing clear documentation.
The ideal Angular developer should also be able to tell you about their experience with automated testing, deployment pipelines, and working in an agile environment.
