Ask HN: Listing unrelated work experience on the CV

I'm 40 years old and I worked lots of jobs before I turned into a software developer last year. I only have 1.5 years of software development experience.

However, whenever I try to mention my older work experience during the first interview screeners, 2 HR people got angry for omitting my experience. I told them that I'm not listing everything because that'll take 2 pages and not everything contributes to my profile. They ghosted me.

I'm seriously thinking that it's covert ageism, but part of me also wants to list it to dodge the bullet of ageism before the figurative gun is fired. Advice?
