The problem is that “experience” has no value in our industry, unless it is recent experience with some technology, framework, language, and the memorization of those algorithms and data-structures.
About 10 years ago, I was looking for jobs, and wasn't getting any bites. My wife said "Cut your resume in half. Only show the last 7 years of your employment history."
It worked--when it wasn't so obvious that I was a graybeard, I got a lot more interviews. But it was epochally, cosmically sad for me to cut out 15 years of my experience--describing achievement I was really proud of. And just throw them in the trash.
