DSA is asked in almost every place. If you can do at least leetcode medium by yourself without any hints, then you can clear most company's DSA round.
If u haven't done DSA, then you can speed run the InterviewBit problem set (contains ~270 qsns).
A🧵on ReactJS Internals. What is "rendering" in React? When does re-rendering happen? What is reconciliation and Virtual DOM etc?
It will help to clear every frontend interview.
Will post this thread in 3 parts.

In React, we write "JSX". It is a syntax extension for JavaScript that looks similar to HTML.
Browsers do not understand JSX directly, so it is transformed into a JavaScript Object (this JS object is called "React Element") with the help of a compiler called "Babel".

A 🧵on Apache Kafka.
It is most widely used to make the backend system scalable.
Maybe a long thread, but it's worth reading. Don't worry if you have never heard of Kafka or message queues. I have covered everything from the beginning.

Kafka is a message queue.
In a message queue, the producer puts tasks in a queue from one end, and the consumer/worker pops out those tasks from the other end and performs the operation.
Why do we need it?
Suppose there is a route /buy-product.
