I was invited to an interview for this graduate role and when I arrived on the day of the interview, I realised it was more an assessment centre process than in actual one-by-one interview. All the candidates were actually surprised (7 persons at the same time). Initially, we all entered in a room where we were presented the general overview of the company and we filled a hard copy test for 20 minutes. Then they took us a tour within the company's infrastructure to explain us which part was what. Finally, I had a one-by-one interview.
