💬 Potential Interview Questions

Here are 10 technical interview questions tailored to the Netskope UI Engineering role, along with brief answers:

What are the key differences between AngularJS and Angular2+?
AngularJS is based on MVC and uses JavaScript, while Angular2+ is component-based and uses TypeScript, offering better performance and scalability.
How would you ensure cross-browser compatibility in a web application?
By using CSS resets, feature detection (like Modernizr), consistent testing across browsers, and polyfills for unsupported features.
Can you describe the lifecycle hooks in Angular and their use cases?
Hooks like ngOnInit, ngOnChanges, and ngOnDestroy help manage component initialization, change detection, and cleanup respectively.
How do you optimize the performance of a complex Angular application?
Techniques include lazy loading modules, using trackBy in *ngFor, avoiding memory leaks with unsubscribe, and using ChangeDetectionStrategy.OnPush.
What are the advantages of using TypeScript in Angular development?
TypeScript provides static typing, better tooling (like autocompletion and refactoring), and early error detection, improving code quality.
How do you handle communication between components in Angular?
Through @Input and @Output decorators, shared services with Observables, or state management libraries like NgRx.
What are common web security vulnerabilities and how do you mitigate them?
XSS (sanitizing input), CSRF (using tokens), and secure authentication practices help protect against common threats.
How do you structure a scalable and maintainable UI component library?
By using atomic design principles, encapsulating styles, and creating reusable, well-documented components with clear inputs and outputs.
What is your approach to REST API integration and error handling in the frontend?
Use Angular's HttpClient, handle errors with interceptors and RxJS operators like catchError, and provide user-friendly error messages.
Describe your experience with version control systems like Git.
Experienced in branching strategies (e.g., GitFlow), conflict resolution, code reviews via pull requests, and CI/CD integration.
