Applied online through gradcracker, filled out their form. Got an email soon after with a link to some online activities; psychometric, personality and skill/technical test, all of them were quite game-like. About two months later I was contacted via email regarding an interview and a brief which detailed an old, stone bridge with one side showing signs of soil contamination. I had to prepare a 10 minute presentation to discuss and justify whether renovation or demolition would be suitable, about an hour of research and prep is recommended by them. The email also detailed that technical questions would be asked alongside my presentation. When I arrived, they started by offering a glass of water, starting with the technical questions and then finishing with my presentation. Lasts about an hour and a half.
