Smooth and based on my resume, mainly on frontend basics(like 302 meaning in response, difference between stateful and stateless, ways of communication between frontend and backend, etc), and tested a coding problem to build a calculator using string inputs.

The OA was pretty easy but i got nervous and messed up the 3rd question. so if you're giving their oa just clear the basics of js and react for me it was a book management system had to display data, sort and fetch it from api.
