🎯 The Hacker's Blueprint (What Actually Works)
1. Master the "Why" Behind Every Feature
Don't just say "NgRx is for state management."
Say: "We use NgRx when multiple components share data and actions need traceability. For smaller apps, a BehaviorSubject service is cleaner."

Hack #2: The Destroy Ref Trap (The one nobody passes)
The Question: "You have a stream of WebSocket events. The user navigates away. How do you unsubscribe?" Decoded Frontend - Angular Interview Hacking %21%21TOP%21%21
The Rookie Answer: takeUntil(this.destroy$) in ngOnDestroy.
The Hacked Answer:
"That works, but it’s boilerplate heavy. In modern Angular, I use takeUntilDestroyed() with the new destroyRef injection context. Better yet, if I’m lazy, I use toSignal() from RxJS, which automatically unsubscribes for me."
// The "I actually ship code" move.
private destroyRef = inject(DestroyRef);
ngOnInit()
interval(1000).pipe(
takeUntilDestroyed(this.destroyRef)
).subscribe(console.log);
Translation to the interviewer: "I don't leak memory. I read the Angular changelog."

10. Sample whiteboard answers (short templates)
- "Why NgRx?" — Use when many components share complex async state and you need time-travelable, predictable updates; otherwise prefer service-based state.
- "How to optimize a slow page?" — Profile; reduce initial bundle (lazy load), OnPush, virtual scroll, memoize heavy ops, compress assets.
- "Implement search debounce?" — Use FormControl.valueChanges.pipe(debounceTime(300), distinctUntilChanged(), switchMap(...)).
