"IBM employs a system of Bands to classify consultants. It works approximately like this: Band 6: Consultant, Band 7: Senior Consultant (most new MBA graduates get here), Band 8: Managing Consultant, Band 9: Senior Managing Consultant, Band 10: Associate Partner. Above Band 10 is the partner level. "
I think Band 8 at IBM is higher, but go on which pays more as well. C3 at Capgemini is middle of the road. C4 is Managing Consultant.
