Basically they ask very basic questions related with javascript and react.js for example promises , how to handle states etc type. and the interviewer was very polite and good my interview round was virtual.

First round was coding with 3 questions related to graphs. Further was the telephonic interview. Didn't get through the further rounds. Prepare well on Haskell or Purescript. All questions base is similar only differs on what they want from the graph.
