First filled out an online application form and sent my cv. Was invited to an interview soon after. In the interview we were first given a detailed presentation by someone from the group. We then went for a group exercise based on logic. Neither group got the right answer, I'm not even sure if there was one but the exercise was to see how you worked together. We then sat in a room in silence doing numerical and verbal reasoning tests for an hour or so. After that we had lunch and most of us got sent home while some stayed for interviews. That part was really quite humiliating, especially after putting so much effort into the morning.
