Larger consulting firms will have different levels of consultants–associate consultant, consultant, senior, manager, and principal–and will pair newer consultants with more experienced ones. Three years later I’m earning a very comfortable living consulting and I get to work on super interesting projects with super interesting companies. If next year I decide to switch from marketing consulting to, say, operations consulting or sales consulting or illustration work or some narrow marketing thing like site conversion optimization, I just update my website headline it’s done.
