I applied via Recruitment Consulltant and was interviewed in Oct 2022. There were 4 interview rounds.
Angular Hooks are functions that allow you to execute code at specific stages of a component's life cycle.
ngOnInit() - called after the component is initialized
ngOnChanges() - called when the component's input properties change
ngDoCheck() - called during every change detection cycle
ngAfterContentInit() - called after content is projected into the component
ngAfterContentChecked() - called after every check of projected ...
Lazy loading is a technique to load modules on demand instead of loading everything at once.
Lazy loading improves the initial load time of the application.
It splits the application into smaller chunks that can be loaded when needed.
In Angular, lazy loading is achieved by configuring the routes with loadChildren property.
Syntax for routing path with lazy loading: { path: 'lazy', loadChildren: () => import('./lazy/lazy.m
I applied via Approached by Company and was interviewed before Sep 2022. There were 2 interview rounds.
Data binding is the automatic synchronization of data between the model and view components in an Angular application.
Data binding allows for the seamless communication between the component class and the template.
There are four types of data binding in Angular: Interpolation, Property binding, Event binding, and Two-way binding.
Example: {{ title }} in the template binds the value of 'title' from the component class to
Life cycle hooks are functions that allow you to tap into the lifecycle of Angular components.
Life cycle hooks are predefined methods that get called at specific points in the component's life cycle.
They allow you to perform actions like initialization, change detection, and destruction.
Examples of life cycle hooks include ngOnInit, ngOnChanges, and ngOnDestroy.
Lazy loading is a technique in web development where resources are loaded only when needed, improving performance.
Lazy loading helps reduce initial load time by loading resources on demand
It is commonly used in Angular for loading modules, components, or routes asynchronously
Lazy loading can improve user experience by only loading necessary resources when required
Using services or shared state management libraries like RxJS or NgRx
Use services to store and share data between components
Use shared state management libraries like RxJS or NgRx for complex data sharing
Use @Input and @Output decorators for parent-child component communication
Forms in Angular are used to handle user input and validation.
Template-driven forms: Uses directives like ngModel to build forms in the template.
Reactive forms: Uses form control objects to build forms programmatically in the component.
Form validation: Angular provides built-in validators like required, minLength, and custom validators.
Form submission: Forms can be submitted using ngSubmit event or formControl methods.

Promises are used for a single asynchronous operation, while observables are used for multiple asynchronous operations over time.
Promises are eager, meaning they start immediately upon creation. Observables are lazy, meaning they only start when subscribed to.
Promises can only handle a single value, while observables can handle multiple values over time.
Observables are cancellable, while promises are not.
Observables pr...

This was an easy round which went really smooth.
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2)
, with initial conditions F(1) = F(2) = 1
.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).
Ensure the input N is within the constraints 1 <= N <= 10000.
Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
Given a positive integer N
, your task is to determine and return all prime numbers less than or equal to N
.
N = 10
2 3 5 7
N = 20
Implement a function to return all prime numbers less than or equal to a given positive integer N.
Create a function that takes a positive integer N as input
Iterate from 2 to N and check if each number is prime
Use a helper function to determine if a number is prime
Return an array of all prime numbers less than or equal to N
A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
Merge join is used when joining two large datasets that are already sorted.
It is more efficient than other join methods like nested loop join or hash join for sorted datasets.
The join condition must be an equality condition.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i
