- General about Reactjs (15 minutes)- You have gathered 5 years of knowledge in react, 15 minutes will not determine whether you are capable or not. I believe its just a formality of how confident are you with working the library you are using for so long. - 45 minutes was for algorithmic questions. I was asked of Text justification (hard leetcode) from the start. I immediately knew the interview was going to be hard lol. The question was modified. Instead of space it was hyphen. They would immediately ask another question modifying the same question and making it somehow a little bit hard. But my thoughts on it are positive because if you know about the concept then you can easily solve it.
