Concerned more about native JavaScript irrespective of library or framework which is a good thing. Candidates are required to go through js core concepts. React class based components and redux were also asked.

Have first round of interview which had questions regarding Javascript and React js. It included basic question of JavaScript and some Tricky react js questions. It was the first round so not much was asked. Just some basic Java script questions and Some React js based questions like difference between class based components and Function based components.
