Oracle Graduate Consultant Program interview questions

Applied through Pareto (Recruitment Firm) invited to attend an Assessment Centre in Reading. About 40 candidates there . Everyone introduced themselves and stated their greatest non-academic achievement. Group Tasks - too many people on a boat, who should stay on it & rank 15 items in order having crash landed in a desert via plane. 3 min pitch to management why you want a career in consulting and why Oracle. Half the candidates leave at lunchtime. Afternoon consist of Q&A with current graduates, but throughout the day you go off for a 30 min interview with the manager/director of the service line that you have chosen. Once all candidates have been interview, the 20 of us got split into 3 groups to be told of the outcome. Some will start in March as they have graduated, some undergrads to start in July and the remainder were unsuccessful. Lunch was provided, I don't think travel was expensed but I never asked. Some people were told that they were successful but formal offers wouldn't be made until April/May because it depended on Oracle's performance in the quarter to determine whether they needed extra capacity to take us on. Found this odd because we were successful but no definite offer has been made.
