Starts with 2 tests, numerical and financial. The numerical test is a bit of a joke, 20% of 250 was one of the questions for example. Financial test is fine, if you don't know something then just google it, it's not hard. Then an Excel test, most people have described that already so I won't go into too much on it. Bit of google on that will help you through as well. Next stage is a Google Chat interview, my interviewer seemed very disinterested but that seems to be a theme with this company. After that is an assessment centre and then interviews with two managers. General feel was this was a lot more finance based than other consultancy interviews so make sure you look at each of those sections on their website. Also, the job isn't like other consultancy jobs so take that into consideration.
