Interview
The interview process has 4 rounds: recruiter screen, 2 technical rounds and one final round with the HM.
The 1st technical round was about data modeling, taxonomies, data cleanliness and Leetcode.
The 2nd technical round focused on pandas, and using it to answer questions from a dataset. Statascratch should help, but you should also know the various functions of pandas by heart.
