well the AC for my assessment revolved around arriving at 8.30, doing numerical and verbal tests, with the numerical tests being slightly harder than the online tests, made that bit harder by the basic calculators which were given to us.
Then we had a biographic interview, which involved just talking about urself and your aspirations, and then quite a lot on commercial side, requiring knowledge about barclays, its market and its competitors.
then there was lunch, then there was a group exercise, which was on a very tight time frame, with only 5 minutes to read info, it looks good if you try and keep the group on track. at the end you have to present and answer questions on your choice, as a group.
the competency interview, was pretty relaxed, and was far more interactive, then many competency questions. I do remember a few questions on leadership in this interview.
a key difference with the AC, was the amount of assessors there were, easily outnumbering candidates two to one.
I hope this is helpful london_mai.
