Round 1

This round was around JavaScript/React fundamentals and one machine coding problem. It was divided into two parts:

• Part 1: Questions around core JavaScript and React fundamentals. We discussed about Hoisting, Closures, React Hooks, Event Loop (Recommend Resource), Websockets, Promises, CSS (flexbox, grid), and similar web fundamentals. It was a very fluid conversation.

• Part 2: I was asked to build a grid of cells and toggle functionality around it, it was called Grid Toggle (Solve here).

Round 2

This round was full fledged machine coding round. I was asked to build an interactive chart bar component from scratch using React, without any existing charting functionalities. I had to implement mulitple functionalities with some basic UI animations.
