How to migrate a legacy NgModule app to a standalone, Signal-driven application.
The key differences from AngularJS (the 1.x version):
This layered approach is precisely what the Decoded Frontend "Interview Hacking" course emphasizes, with each topic tiered from Junior to Senior levels.
Decoded Frontend - Angular Interview Hacking !!TOP!! Breaking into a senior frontend role or transitioning into modern, enterprise-level Angular development requires more than just a basic understanding of components and data binding. The modern Angular ecosystem (featuring standalone components, Signals, and reactive architectures) demands that developers master both core JavaScript fundamentals and deep Angular internals.
If you are working on an older codebase or transitioning to modern Angular, you must understand ChangeDetectionStrategy.OnPush .
ngOnInit() interval(1000).pipe( takeUntilDestroyed(this.destroyRef) ).subscribe(console.log);

Technical interviews rarely test if you can write basic components. Instead, they evaluate your mental model of the framework. "Interview Hacking" is not about memorising answers; it is about structuring your responses to demonstrate deep architectural awareness.
Interviewers use these foundational questions to differentiate between developers who only know how to build screens and those who understand why Angular works the way it does. Modern Angular has shifted significantly, and your answers must reflect this evolution.
If they ask about @defer triggers, remember: on interaction for modals, on viewport for footers. Never guess. Decode.
As Aristeidis Bampakos (GDE for Angular) noted, the depth of content demystifies complex Angular concepts that are otherwise difficult to grasp. This is the "hacking" approach: learning the framework so thoroughly that you can anticipate questions before they're asked.
: Route-level lazy loading reduces the initial bundle size. Use the loadComponent syntax for standalone components.
Directives are markers that tell Angular to add behavior or modify the DOM dynamically. There are three main types:
You can handle authentication and authorization using techniques such as token-based authentication and role-based access control.
Class-based guards ( CanActivate , CanDeactivate ) are deprecated. You must know how to write functional guards using inline functions or injectable tokens. typescript
: This modern control flow allows you to defer the loading of heavy components, directives, or pipes until specific conditions are met (e.g., on visible , on idle , or on interaction ).
