The concept of debounce time for optimizing API calls in type-ahead scenarios is also discussed. • Form Handling (27:40-29:02): The candidate differentiates between template-driven and reactive forms, explaining when to use each and how to structure reactive forms for complex data. • Custom Directives and Pipes (29:05-30:48): The importance of pure pipes for performance and examples of custom directives (e.g., safe HTML, phone number formatting) are covered. • NGRX (State Management) (30:50-33:50): The interview touches upon NGRX, explaining the roles of actions, reducers, effects, and selectors in state management. • Unit Testing in Angular (33:53-35:20): The three phases of unit testing (arrange, act, assert), mocking services using 'spyOn , and testing error scenarios are discussed. • Candidate Questions (35:25-37:28) angular interview questions and answers angular interview questions angular interview questions for 3 years experience angular interview Angular interview questions and answers for experienced 2026 Angular interview questions and answers for experienced 2024 #Angular #AngularInterviewQuestions #AngularInterviewQuestionsAndAnswers #AngularInterview #AngularInterviewQuestions2025 #AngularInterviewQuestionsForFreshers #AngularInterviewQuestionsForExperienced #FrontendInterview #WebDevelopment
