Alessandro Costanzo

After a long career in the hospitality sector, Alessandro discovered The Information Lab thanks to a demonstration carried out at the University of West London, where he graduated in hospitality management. Alessandro was positively impressed by the hiring process of The Information Lab, which was based on the creation of a project rather than being tied with CV’s.

Since then Alessandro has pursued a career change towards data visualisation. Applying to the Data School was his first real attempt in this direction. The teaching and placements activities seem perfect to provide Alessandro with a solid foundation to successfully begin his career change path.
