Angular Developer Interview Round 2 – Must-Know Concepts with Real Examples
Angular Developer Interview Round 2 – Must-Know Concepts with Real Examples
💼 My Angular Developer Interview Experience | Round 2 – Angular Fundamentals
Welcome to Round 2 – Angular Fundamentals Interview Questions!
In this video, I share real Angular questions that were asked in my technical interview. These aren’t just theory — they test your understanding of core Angular concepts, lifecycle hooks, forms, dependency injection, RxJS, and zone.js.
Here’s what we’ll cover:
1. Template-driven vs Reactive Forms — when to use which
2. setValue() vs patchValue() in Reactive Forms
3. Handling form errors and validations
4. Lifecycle hooks — ngOnChanges, ngDoCheck, ngAfterViewInit, and why @ViewChild works there
5. Dependency Injection and use of services in constructors
6. Role of zone.js and how it triggers change detection automatically
7. Unsubscribing using takeUntil and takeWhile in RxJS
8. ReplaySubject vs BehaviorSubject — key differences
If you're preparing for an Angular interview, this video will help you understand how to think through real scenarios, not just memorize answers.
