Work Experience. This section should include all relevant paid work experience, including internships. Volunteer or charity work should not be included in this section, or often at all (see below). Make the title of this section a reflection of your paid experience: “Work Experience”, “Employment History”, and “Work History” are all appropriate titles. This should be listed above “Education” unless you are a recent college graduate, since that information is most pertinent to employers.
You should also include information about promotions in this section. When listing your responsibilities, start with the most valuable experience first, since the employer will likely be skimming your resume top-down.
