No one cares about hobbies, and Kaggle is a hobby.
An NCG should write more about class projects. Everyone has class projects.
If an NCG wants to put it down, fine. But don't color me impressed. Why should I select someone that spends their evenings alone tweaking out an extra 0.001% on a AUC curve, when I could conceivably get a more rounded individual with better team skills?
A person just outside of university does not have heaps of past jobs to show. So they should just leave it blank and describe their hobbies?!
