Adobe Graduate Sales Executive interview questions

Applied through Pareto looking for a Business IT / Analysis Role. Told this would be a similar role, would involve lots of IT and Analysis. Had to prepare a presentation before 'Why I want a Career in Sales?' - was informed that I can talk about the business Analysis/ IT aspect. When I got there I quickly found out that it was just a pure sales role. I kept upbeat about it but it did not last long. There were about 50 people there and we all had to start by introducing ourselves and an 'inspirational person'. There were 2 group activities with 10 people in each group. It involved decision making exercises and a vague way of advertising yourself. There was also a presentation we had to give (not in a group, something that was prepared before - Presentation was ' Why I want a career is Sales?' There was a very short 1-1 interview as well. The main issue with the day is that it started at 8am and ended at 6pm. I understand that it is meant to be an intense day but for most of the day you are waiting for the next stage of the process and as you are in groups of 10 everyone talks over each other. Even if you try to take the lead and calm things down, it does not work.
