Journey
I applied to the BarRaiser company through LinkedIn Easy Apply. Then, after applying, HR contacted me for the initial screening round in about 3-4 days. He asked me basic questions about my experience, knowledge, location, etc. After that, I received an interview link from BarRaiser. There were two technical rounds. After I cleared my first round, HR contacted me and scheduled the second round 2 days after the first round. After the second round, I got an offer letter and joined the company a week later.

Coding problem2
The Interview was from 11:30AM - 12:40 PM in the afternoon. Interviewer was very good, he asked me some very tricky and complex problems.
1. CSS Problem
He asked to make 16 divs and align them so that the space between every div vertically and horizontally will be the same. Each row should consist of 4 divs. You are not allowed to use the grid CSS property.
Problem approach
For this problem make 4 div element and in each div make 4 div element. You have to give flex property to parent div element and wrap all this in another div element and give css property of flex-direction column

2. Theory Questions
Problem approach
Redux is more powerful than Context API, with features such as:
Predictable state management: Redux provides a predictable way to manage state, which makes it easier to debug and test applications.
Time-travel debugging: Redux allows you to step back and forth in time to see how your application's state changed over time. This can be very helpful for debugging complex applications.
Developer tools: Redux has a rich ecosystem of developer tools that can make it easier to develop and debug Redux applications.
