How much detail should I give to jobs from 20 years ago or to jobs with companies that have gone out of business?
(Lake Worth FL)
Is my work duties from 25 years ago going to interest a potential employer or just make my resume too long?
Your instincts are good, David. Most resumes need only include 10 to 15 years of work history. Experience beyond that is just not going to be of much value in most cases. Include what is most relevant now.
I wouldn't not list a company that's gone out of business, though, if you were employed there recently. Do include it, but explain in your cover letter that they won't be able to verify employment because the company no longer exists.
