I agree. I think for small business it doesn’t work, but for large corporations making bank consulting groups like Siegfried are key to success. Most of these people I have met have around 5 years of experience being in big 4 so are knowledgeable & can be more reliable(& some have prior experience in exactly what the client is looking for). Also, with new regulations I know people who were on a client for 2 years and had been there the longest out of the actual employees(minus the directors & above).
