Of course you’re “old”. I’m older. So what? Fly that freak flag (as if your age is the freakiest thing about you).
On my own résumé I not only put down those dates very plainly, but I also add my college / university attendance and write very clearly next to that: “Did not graduate; no degree attained,” so that there can be no possible claim of résumé padding or false claims. I’ve been told more than once by interviewers that when they see that (at the top of the document) they’re more inclined to read further with a clear expectation of “the truth, and nothing but the truth”. (That’s “when I get to the interview stage, of course. There have been a lot of potential interviews that I probably missed out on.)
Those who rely on “the degree” and “the age” more than “the actual qualifications and requirements for performance of the job”, well, I’m just as unwilling to work for them as they are to hire me in the first place, so we weed each other out that way.
