I applied through the website and was then invited to take the online assessment. This was fairly straightforward and heavily focused on competency - be sure to practise as there are plenty of websites out there. I was then invited to the first round stage which involved an informal interview with a member of the HR team and a group task. Again, the interview was competency based and very informal. The interviewer was very interested in my past employment and reasons for wanting to change career. The group task was enjoyable. You're given a scenario (two banks seeking to merge in my case) and numerous solutions. You had to work with your team in the time frame to decide on a solution in a set time and then present it to another group and the assessor. After this I was invited to the final stage which involved a one-to-one interview with a senior manager. My interviewer was extremely friendly and encouraging and I enjoyed the experience. Be sure to know you're stuff about Accenture and reasons for wanting to work there and have plenty of genuine examples to demonstrate your competencies.
