I applied via campus placement at National Institute of Technology (NIT), Patna and was interviewed in Aug 2024. There was 1 interview round.
A program to find prime numbers within a given range
Iterate through numbers in the given range
Check if each number is divisible by any number other than 1 and itself
If not divisible, it is a prime number
Count the number of ones in a given number using pseudo code
Initialize a count variable to 0
Iterate through each bit of the number and check if it is 1
Increment the count if the bit is 1
Return the count as the result
I applied via Referral and was interviewed in Sep 2024. There were 2 interview rounds.
Merge sort has a time complexity of O(n log n) in the worst case scenario.
Merge sort divides the array into two halves, sorts them recursively, and then merges them back together.
The time complexity of merge sort is O(n log n) in the worst case scenario.
For example, sorting an array of 8 elements would take 3 recursive calls to merge sort.
Create a palindrome checker using React JS to display on the UI
Create a input field for user to enter a string
Use state to store the input string
Create a function to check if the input string is a palindrome
Display the result on the UI
Javascript question on promise, callbacks, hosting
I applied via Walk-in and was interviewed in Apr 2024. There were 3 interview rounds.
Javascript array questions like palindrom and others with aptitude
Data can be shared between components in React using props, context, or state management libraries like Redux.
Use props to pass data from parent to child components
Use context to share data across multiple components without passing props manually
Use state management libraries like Redux to manage global state and share data between components
Prop drilling is the process of passing data through multiple levels of components in React.
Prop drilling occurs when a component needs to pass data to a deeply nested child component.
It can lead to code that is hard to maintain and understand.
One way to avoid prop drilling is by using Context API or Redux for state management.
Redux is a predictable state container for JavaScript apps.
Redux stores the entire state of an application in a single immutable object.
State changes are made by dispatching actions, which are plain JavaScript objects.
Reducers specify how the application's state changes in response to actions.
Redux flow: Action -> Reducer -> Store -> View

Programming is the process of writing instructions for a computer to perform specific tasks.
Programming involves writing code using programming languages.
It requires problem-solving skills to break down complex problems into smaller, manageable tasks.
Programmers need to understand algorithms and data structures to optimize code efficiency.
Debugging and testing are essential to identify and fix errors in the code.

DOM stands for Document Object Model, it is a programming interface for web documents. It represents the structure of a document as a tree of objects.
DOM is used to interact with HTML and XML documents in a structured way
It allows developers to manipulate the content, structure, and style of a website dynamically
DOM provides methods and properties to access and modify elements on a web page
Example: document.getElementB...
The output will display the document object in the console.
Typing 'document' in the console will return the document object, which represents the current HTML document.
The document object provides access to the content and structure of the webpage, allowing manipulation of elements and properties.
I applied via LinkedIn and was interviewed in Jan 2024. There was 1 interview round.
A hash map is a data structure that allows for efficient storage and retrieval of key-value pairs.
A hash map uses a hash function to convert keys into array indices.
It provides constant-time average case complexity for insertion, deletion, and retrieval operations.
Hash maps are commonly used in programming languages and databases for fast data access.
Example: HashMap
