I applied online and got a call from recruiter. They take interviews only on weekdays. He called me at 10 am. The process was smooth. They have four rounds 3 technical and 1 hiring manager round. First round is problem solving, data structures and algorithms. Next 2 rounds are based on core Javascript. Though the interview might have React.js in description but they will stick to core JS.

Worst, was set to 10am EST, they showed up on zoom at 10amCST because they were conducting from India. At some point 5 people were sitting in zoom, was asked to implement merge two objects, they did not like my 5 line solution with reduce, instead they showed me 20-30 line solution with lots of memory usage and lots of unnecessary loops saving them in multiple variables, yet they called me not senior enough
