There were 3 rounds- First 2 rounds purely technical Javascript & react based.. No theory they directly ask me to share screen and start coding.. One weird thing was to take interview they were not prepared with any specific platform where I can have some skeleton code and then I can create a component and run it.. They were asking me to open any online compiler and start from scratch.. every round was approx 2+ hours and they expect the program should pass all test cases..
