1 hackerrank which had sql, data structures and algorithms and a Machine Learning problem to be solved on the Jupyter notebook, and then final round with hiring manager for 45 minutes
It was good and very well structured but didn't get offer as I didn't have a data science background but learnt a lot. Both rounds were very good. The first round was conducted by karat and then the second round was by someone in the team
