Angular is deeply integrated with reactive programming. Senior-level interviews will heavily test your ability to manipulate asynchronous data streams cleanly. High-Order Mapping Operators

: Introduced in Angular 14, these allow components to be used without NgModules , simplifying code structure and enabling easier tree-shaking. Transitioning a component to ChangeDetectionStrategy

Angular has shifted toward a standalone architecture. Standalone components, directives, and pipes eliminate the need for traditional NgModule files. They specify their own dependencies directly in their metadata.

When asked how you would structure a large enterprise application, present a clean, domain-driven structure like this: Below is an original, highly scannable blog post

Discuss the separation of concerns. Break your application into container components (smart components handling data fetching) and presentational components (dumb components receiving data via inputs and emitting events via outputs).
