bet365 Graduate Trainee interview questions

I was invited to attend Assessment Center. It was whole day. We had to build a tower as a group, they were testing our negotiating skills, team work, communication. We had 10 mins to complete a numerical test it was very easy just multiply, division, fractions. Than we had a case study about the service in a hotel and we had to prepare a presentation as a group how to improve service as well prepare financial plan. Then we had to present it infront of three people and they asked as many questions. At the end we had another test Who would you save from a cliff? You have 6 people and you can save only 3. Person specification was provided and you had to judge them based on that.
