This. I have also interviewed a handful of people that had 20, 30 years of experience building software. In some cases, they had resumes pages long dating back into the late 80s. One tip I would stress to anyone who has been doing software engineering that long? Don't list all of the history you've ever had. Go back maybe 10 years. If you're worried someone might miss something you built from 15 years ago, just put "more job experience history available upon request" or something like that. The simple truth is having built something in Delphi in the 90s just isn't going to 'help' you working with today's frameworks, even though the underlying core software engineering skills will almost certainly be relevant regardless of language, toolset, or framework du jour.
