Use the reverse chronological format, listing experience before education. State what you did, where, and when. Provide substantive details on important building blocks, current skills, and successes relevant to the type of career you want to continue to develop. Since you plan to enhance your current skill set in some way with the MBA, phrases such as "worked a total of three years in [a certain function or industry]" and "worked in conjunction with three departments, including [list of departments]" help clarify your level of current knowledge and exposure to a function or industry.

In addition, if there is a clear way to define the scope of your responsibility without the advanced degree, point this out in your experience. For example, "As an analyst, did research and budget analysis to assist the firm’s associates (MBA-level) in preparing for client presentations."
