Present a demo lecture that last at least an hour on an assigned topic such as principle component analysis, optimization or any other data science related topics. There is also a python coding challenge on a white board. Nothing too difficult there if you have practiced as a data scientist before. You do have to use Python since the course is taught in the language. Finally, there could be a data science interview focusing on the theory. This interview covers the most common data science topics including frequentist stats and machine learning.
