Always put dates on your resume
OK, so I can’t just leave it like that, though there’s not much more than needs to be said.
Not having dates on your resume, raises questions and concerns in the recruiters’ mind, and will get you into the rejected pile.
But lets face it, most companies accept there’ll be many older workers in the workforce.
Therefore, the bias against older workers is a lot less, (though not completely gone unfortunately).
Finally, not being completely truthful about your age (or anything else for that matter) tends to end badly, regardless of how senioror junior you are.
