Angular's Enterprise Focus
Why Companies Choose Angular
1. Complete Framework
Unlike React's "bring your own router" approach, Angular includes everything:
- Built-in routing
- HTTP client
- Form handling (reactive and template-driven)
- Dependency injection
- Testing utilities
2. TypeScript-First
Angular has used TypeScript since Angular 2 (2016). This means:
- Strong typing throughout
- Better IDE support
- Easier refactoring
- Fewer runtime errors
3. Consistency at Scale
Angular's opinions mean all Angular projects look similar:
- Standard project structure
- Common patterns across teams
- Easier onboarding for new developers
- Predictable code reviews
Angular Version History (Important for Hiring)
Angular (2+) vs AngularJS (1.x)
AngularJS (1.x) - Legacy, end of life December 2021
- Very different from modern Angular
- No TypeScript
- Different architecture
- Many apps still exist but shouldn't be started
Angular 2+ - Modern Angular
- TypeScript-based
- Component architecture
- Regular major releases
- Continuous evolution
Current Version (Angular 17+)
- Signals for reactivity
- Standalone components (no NgModules required)
- Improved performance
- Better developer experience
Interview Question: "What version of Angular have you worked with? Have you migrated between major versions?"
Skills to Evaluate
Core Angular Concepts
1. Components and Templates
- Component lifecycle hooks
- Input/Output decorators
- Content projection
- Change detection understanding
2. Dependency Injection
- Service creation and injection
- Provider scopes (root, module, component)
- Testing with mock services
3. RxJS and Observables
- Observable operators (map, filter, switchMap)
- Subscription management
- Async pipe usage
- Error handling
4. Forms
- Reactive forms vs template-driven
- Form validation
- Complex form patterns
Modern Angular (17+)
- Standalone components
- Signals for reactive state
- New control flow syntax
- Deferred loading
Angular vs React: Hiring Implications
| Aspect | Angular | React |
|---|---|---|
| Talent pool | Smaller, specialized | Much larger |
| Enterprise adoption | Strong | Growing |
| Learning curve | Steeper | Moderate |
| Structure | Opinionated | Flexible |
| TypeScript | Built-in | Optional |
Hire Angular developers when:
- You have an existing Angular codebase
- Building enterprise applications
- Team values strong conventions
- Long-term maintainability is priority
Interview Questions That Matter
Understanding vs. Memorization
Bad question: "What are the Angular lifecycle hooks?"
Good question: "When would you use ngOnChanges vs ngDoCheck?"
Bad question: "What is dependency injection?"
Good question: "How would you share data between two components that aren't related?"
RxJS Understanding
Angular developers MUST understand RxJS. Ask:
- "Explain switchMap and when you'd use it"
- "How do you prevent memory leaks from subscriptions?"
- "When would you use BehaviorSubject vs Observable?"
Common Hiring Mistakes
1. Conflating AngularJS and Angular
They're completely different frameworks. AngularJS (1.x) knowledge doesn't transfer well. Make sure candidates have Angular 2+ experience.
2. Ignoring RxJS Skills
Angular is deeply integrated with RxJS. Weak RxJS skills mean constant struggles. Specifically assess observable handling.
3. Assuming React Skills Transfer
The mental model is different. React developers need significant ramp-up for Angular's DI, modules, and RxJS patterns. Plan for 4-6 weeks minimum.
4. Not Specifying Version
Angular 12 and Angular 17 are quite different. Be specific about which version experience you need, especially for standalone components and signals.
Recruiter's Cheat Sheet
Resume Green Flags
- Specific Angular version mentioned (Angular 15+)
- RxJS or reactive programming mentioned explicitly
- TypeScript as a primary skill
- Enterprise or large-scale application experience
- Testing frameworks (Jest, Karma, Cypress)
- State management experience (NgRx, services)
Resume Yellow Flags
- Only AngularJS (1.x) experience—it's a different framework
- No mention of RxJS—critical for Angular
- Generic "JavaScript frameworks" without specifics
- Very old Angular version experience only
Conversation Starters
- "Which Angular version are you most experienced with?"
- "How do you handle subscription management in Angular?"
- "Tell me about your experience with RxJS operators"
- "Have you worked with standalone components or signals?"
