You can add, change, or remove a job, internship or contract position among others in the Experience section on your profile. You can also add different skills to each experience, which will appear under the Skills section as well.
Associations with organizations in the Experience section of your profile must be accurately labeled and must reflect professional experience with the named organization, such as employment, contract work, official internship or volunteer experience, board service, among others. Informal associations or non-professional experience with organizations shouldn't be included, such as a customer or user of an organization's products or services.
