The process took 2 months. I interviewed at Barclays in Jan 2012
Interview
barcap ACs consist of 3 components: Personal Interview, Personal Case presentation and group activity
Personal Interview (45 mins): Generally behavioural.
Case presentation (30 mins prepare and 15 mins present): Simple case, but 30 minutes is definitely not enough. This include reading, planning, brainstorm and writing your idea on flipchart.
Group Activity: This is prioritising activity. Given 25 tasks. You are required to choose 5 most important tasks to do in 10 minutes. Then discuss as a group in 20 minutes. Finally, come out with the 5 tasks and present to assessor in 10 minutes. The assessor will sit throughout the discussion.
