I did only the first round which required solving 2 programming questions on glider. The questions were around medium-hard difficulty on leetcode ( I am assuming here since I havent done a lot of problems).
I am not software engineer and haven't practised a lot of these questions and hence they were difficult for me.
Questions had nothing to do with data science or machine learning, they were the same type questions backend engineers would get (from what I've heard)
