To get to the group assessment centre you were obliged to take an aptitude test. If you passed this stage you had to do a video assessment online answering three questions. If you passed this round you were taken to the group assessment centre. You were given three tasks throughout the 3-4 hours you spend there which consisted of a group activity involving a case study that you had to talk about with a company entering a new market. Following that was a competency based interview so prepare a lot of questions and answers for that. The final task was a presentation involving a product that a company wanted to get out onto the market.
