AgileEngine Senior Ruby On Rails Engineer interview questions

The interview went well overall. The interviewer joined a bit late and began by asking basic questions to introduce myself. Then, he shifted to core Ruby-related topics, focusing more on Ruby itself than on Rails. He also asked a few JavaScript questions and requested that I share my screen to solve problems, such as writing a function for sum(3)(4). Later, he moved on to React, a topic I'm not very familiar with, even though the position was for Ruby on Rails. I struggled with the React questions, but I understand that the interview was challenging, especially if your fundamentals in Ruby and JavaScript aren't solid.
