It went bad enough so that I was sent home at lunch time, before the whole assesment day was finished
I messed up the analysis exercise really badly since, despite being up to date with market terminology, I'm completely clueless regarding simple business terms such as 'revenue' and was horrified to find that I was asked to make predictions based on figures. It's painful, I spent a good three weeks preparing for that and then bottled it on something trivial early on in the assessment. The worst thing is knowing that no amount of revision, swotting up or reading would have pointed out to me that I needed to know those terms.
Plus I was also asked some pretty tricky questions, such as 'how is your biology degree going to make you a good corporate lawyer considering it's completely unrelated?' and 'tell me about the biggest formal social event you have organised and how you used your time management skills to ensure it ran smoothly'.
Arse - still, the guys who were there with me were all very nice, so I hope they did well.
