PCA stands for Principal Component Analysis, a dimensionality reduction technique used in machine learning.
PCA is used to transform a dataset into a lower-dimensional space while retaining most of the original information.
It identifies the directions (principal components) in which the data varies the most.
The first principal component captures the maximum variance in the data, followed by the second, and so on.
PCA is ...

I appeared for an interview before Aug 2023.
Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
Allows for easier testing by injecting mock dependencies
Promotes loose coupling between components
Improves code reusability and maintainability
Commonly used in frameworks like Spring in Java

Code is a set of instructions written in a programming language to perform a specific task. Pulses are short bursts of energy or signals.
Code is written in programming languages like Python, Java, C++, etc.
Code instructs computers to perform specific tasks or operations.
Pulses are short bursts of energy or signals used in electronics and communication systems.
Examples of pulses include digital signals in computers and
Data structure is a way of organizing and storing data in a computer so that it can be accessed and used efficiently.
Data structures define the way data is organized and stored in memory.
Examples include arrays, linked lists, stacks, queues, trees, and graphs.
Choosing the right data structure is important for efficient data manipulation and retrieval.

I applied via Campus Placement and was interviewed in Aug 2024. There were 3 interview rounds.
40 technical questions were there.
In total 5 questions were there. Time was alloted per question.
Event bubbling is the propagation of an event from the innermost child element to the outermost parent element.
Events triggered on a child element will also trigger on its parent elements
The event travels up the DOM tree until it reaches the document object
Can be stopped using event.stopPropagation()
Can be useful for event delegation
The .on('click',function() is a more flexible method than .click(function())
The .on() method can handle multiple events and selectors
The .click() method can only handle one event and one selector
The .on() method can also handle dynamically added elements
The .click() method cannot handle dynamically added elements
Function to check if two strings are anagram or not
Create two character arrays from the strings
Sort the arrays
Compare the sorted arrays
Function to determine the order of integers in an array.
Check first and last element to determine if increasing or decreasing
Check for inflection point to determine if order changes
Return order type as string
Optimize images, minify code, reduce HTTP requests, use caching, and lazy loading.
Optimize images using compression and appropriate file formats
Minify code to reduce file size and improve load times
Reduce HTTP requests by combining files and using sprites
Use caching to store frequently accessed data locally
Implement lazy loading to defer loading of non-critical resources
Design a database schema for a movie site with user ratings and recommendations.
Create tables for movies, users, ratings, and recommendations
Use foreign keys to link tables
Include columns for movie genre and user watch history
Algorithm for recommendations can use user watch history and ratings to suggest similar movies
Function to simulate dice roll with equal probability without using random function
Use a toss function that returns either 0 or 1 with equal probability
Call the toss function 3 times and convert the result to a binary number
If the binary number is greater than 0 and less than or equal to 6, return it
If the binary number is greater than 6, repeat the process
Query to fetch duplicate email from table
Use GROUP BY and HAVING clause to filter out duplicates
SELECT email, COUNT(*) FROM table_name GROUP BY email HAVING COUNT(*) > 1;
This will return all the duplicate emails in the table
