In the short term, you should tweak your resume based on each job you apply to. For example, if one position you’re applying to seems to weigh a certain responsibility or focus over another, you should be sure your resume conveys your expertise in this area. At the same time, you should be updating your resume with your experience as it develops, adding any new skills you’ve learned, courses you’ve taken or awards you won.
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.
