4. Sample Angular Developer Interview Questions and Answers

Dive into these sample questions with in-depth answers to assess candidates’ Angular skills:

Q1. Explain the concept of two-way data binding in Angular and provide an example.

A: Two-way data binding allows automatic synchronization of data between the view and the component. An example:

<input [(ngModel)]="name">
<p>Hello, {{ name }}!</p>
Q2. What are Angular services, and how are they used?

A: Angular services are singleton objects that provide functionality and data to components. They promote code reusability and separate concerns.

Q3. Write an Angular component that fetches data from an API and displays it in a template.
import { Component, OnInit } from '@angular/core';
import { ApiService } from './api.service';

  selector: 'app-data',
  template: '<div>{{ data }}</div>'
export class DataComponent implements OnInit {
  data: any;

  constructor(private apiService: ApiService) {}

  ngOnInit() {
    this.apiService.getData().subscribe(result => { = result;
Q4. Explain the concept of dependency injection in Angular and why it’s important.

A: Dependency injection is a design pattern that allows you to provide dependent objects to a class rather than creating them internally. It promotes loose coupling and modular design.

Q5. How does Angular routing work, and how do you configure routes in an Angular application?

A: Angular routing allows navigation between different views in a single page application. Routes are configured using the RouterModule and defined in the app-routing.module.ts file.

Q6. Describe the purpose of Angular directives and provide examples of built-in directives.

A: Directives are markers on a DOM element that tell Angular to perform specific behavior. Examples of built-in directives are ngIf, ngFor, and ngStyle.

Q7. Explain the concept of Angular template-driven forms and provide an example.

A: Template-driven forms in Angular allow you to create forms using Angular directives in the template. An example:

<form (ngSubmit)="onSubmit()">
  <input [(ngModel)]="name" name="name" required>
  <button type="submit">Submit</button>
Q8. How do you handle HTTP requests in Angular applications using HttpClient?

A: HttpClient is a module that facilitates making HTTP requests. An example of making a GET request:

import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) {}

fetchData() {
  this.http.get('/api/data').subscribe(data => {
    // Handle the data
Q9. Explain the concept of Angular directives and provide examples of built-in directives.

A: Directives are markers on a DOM element that instruct Angular to apply specific behavior to that element or transform the DOM structure. Here are examples of built-in directives:

  • ngIf: Conditionally adds or removes elements from the DOM based on an expression’s truthiness.
<div *ngIf="showContent">Content will be displayed if showContent is true.</div>
  • ngFor: Iterates over a collection and generates HTML for each item.
  <li *ngFor="let item of items">{{ item }}</li>
  • ngStyle: Applies inline styles based on an expression’s value.
<p [ngStyle]="{ color: isActive ? 'green' : 'red' }">Dynamic color based on isActive.</p>
Q10. Explain the concept of Angular reactive forms and provide an example.

A: Reactive forms in Angular allow you to build forms programmatically using TypeScript. Here’s an example of creating a reactive form for user registration:

import { Component } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

  selector: 'app-registration',
  template: `
    <form [formGroup]="registrationForm" (ngSubmit)="onSubmit()">
      <label>Name: <input formControlName="name"></label>
      <label>Email: <input formControlName="email"></label>
      <button type="submit">Register</button>
export class RegistrationComponent {
  registrationForm: FormGroup;

  constructor(private fb: FormBuilder) {
    this.registrationForm ={
      name: ['', Validators.required],
      email: ['', [Validators.required,]],

  onSubmit() {
    if (this.registrationForm.valid) {
      const formData = this.registrationForm.value;
      // Send formData to server

By incorporating these additional technical questions and answers into your interview process, you’ll gain a more comprehensive understanding of candidates’ proficiency in Angular development. These questions cover essential aspects of directives and reactive forms, ensuring that you evaluate candidates’ capabilities across a range of crucial Angular concepts.
