very formal, a bit of role play involved, also they would ask how would you approach customers, and what tactics would you use to close the deal. how will you brief the team in morning, where do you see yourself in 5 years time?

one online competency based questions-answers and after that group exercise where each of us got a sheet containing a discussion between an advisor and a customer. We had to discuss between us what the advisor did right, what could have been improved. The assessors were taking notes and were not interfering the conversation. After the group exercise we had 2 role plays. We got a customer sheet, we had to read it carefully and to answer the queries the customer had. You should be careful at the security checks to make sure that what the "customer" is telling you is the exact same thing as on the sheet you have.
