How far back should my resume go?

This is a judgment call. Typically, your resume should go back no more than 15 years. The business landscape changes dramatically on a yearly basis, so anything too far back may no longer be relevant. However, if you would like to return to a career or industry that you had worked in 15+ years ago, then it would be relevant to list it on your resume. A candidate should concentrate on those skills in his or her Profile section and simply list the job entry.
