Online Juptyer notebook, basically mini data science problem. The problem is focused on standard data science stuff, model selection, data processing, etc. This is done in a time constraint so its kinda hard.

smooth process and easy problems overall. Data manipulation and math brainteasears. Nothing too hard. And a bit of resume questions. Overall very standard and smooth processes. Highly recommend applying to this company.
