They invited me to their London headquarters in Canary Warf, which looks amazing. Everything was extremely smooth from the moment I entered the building, I was well received and accompanied to a waiting room with other applicants. After a few minutes an HR employee explained to us how the assessment day would happen. There was two interviews. One technical, and the other non-technical (leadership, management, etc) The technical interview was difficult for me, as I was not a computer science major. I was Electrical Engineering, and knew how to code, but some questions were theoretical.
