Long time-speding rounds for which i spent around +3 hours. Behavioral interviews are hosted in a multiple choice website with videos explaining scenarios. Hosted in HackerRank, there is a coding assessment, a general comp sci knowledge assessment, a math assessment in prob & stats and a whole jupyter notebook to fill with data exploratory analysis and traning a simple model with scikitlearn. No documentation available and you are expected to know by heart the code required. No human involment whatsoever.
