I was/am a software engineer with 40 years experience. I know 15-20 languages, a dozen or so operating systems, virtual, cloud, micro services, full stack, etc. Lots of professional certifications, Masters degree, chairperson of a variety of standards bodies. You get the idea.
All you have to do is say you’ve got so much experience that you’ve programmed on discrete transistor computers and you’ll never get a call. You’re old.
