What is the in your current/latest Angular project? Angular Interview Hacking | Mock Interview with GDE
Angular Interview Hacking is a comprehensive video course created by Dmytro Mezhenskyi , the founder of Decoded Frontend
To truly hack your interview, you must master the following areas, often highlighted in the Decoded Frontend curriculum: 1. Advanced Change Detection (OnPush & Beyond)
The "Angular Interview Hacking" focus area is specifically engineered to simulate real-world technical assessments. It transforms passive knowledge into actionable, high-velocity interview execution, preparing candidates for unpredictable live-coding environments and intense architectural deep dives. 2.

Directives are markers that tell Angular to add behavior or modify the DOM dynamically. There are three main types:
Do not just suggest pagination. Explain how to implement the ScrollingModule for virtual scrolling so that only visible items are rendered in the DOM. Pair this explanation with the use of a custom trackBy function to prevent Angular from destroying and recreating DOM nodes unnecessarily when the collection changes.
Avoid abstract definitions. Provide a concrete code architecture example. Show how an imperative approach relies on manual .subscribe() blocks that mutate local component variables, whereas a declarative approach chains operators together seamlessly, directly exposing a clean data stream to the template via the async pipe. 4.

Without trackBy , Angular recreates DOM elements on every list change, leading to performance degradation in large lists. trackBy allows Angular to track items by a unique identifier and reuse DOM nodes efficiently.
: The instructor shares recommendations based on his experience being on both sides of the interview process (interviewer and interviewee). Practical Application There are three main types: Do not just suggest pagination
"Angular cleans it up." (No, it doesn't.)
// Client: Check if exists before HTTP call const saved = transferState.get(MY_KEY, null); if (saved) // Use saved data AND remove it to save memory transferState.remove(MY_KEY);
A common interview question: The asterisk is syntactic sugar that Angular desugars into an <ng-template> wrapper, allowing the directive to manipulate the DOM structure efficiently. This distinction demonstrates you understand how Angular transforms templates internally.
@Component( selector: 'user-row', template: ` json `, changeDetection: ChangeDetectionStrategy.OnPush ) export class UserRow @Input() user$!: Observable<User>;
