Advanced Structures India React Developer interview questions

I applied via LinkedIn, recruiter called me directly and asked questions regarding my current employer ctc and all, she also asked me some react based questions on the call itself. After this, she arranged my first round of interview with senior developer, in this round he asked me optimizations ways in react application and in depth questions related to my past experience, no react questions asked in this round. I cleared this round. Next round was with two software engineers where the asked me some basic JS output based questions, what is currying what is react fibre? Lots of question related to security and authentications of the web app
