I have tried most things.
I removed all the dates from my CV. No difference; a minimally intelligent pimp can add up. Degree, that's 3y; 3y in this role, 2y in that role, 2 years there, 16y freelancing... This dude is old.
So I removed the early junior jobs from my career history. Result, I got quizzed on how I walked straight into senior roles straight out of university.
So I left out some gaps in the timeline (I've freelanced quite a lot) -- and got curious about the specific tech I'd worked with in particular roles. Deploying Windows NT Server 3.1, or managing a migration from DECnet to TCP/IP, dates you.
You can fool the idiots, sure. But then your CV gets passed to non-idiots.
I don't advertise a DoB any more, nor dates of education, but I do give the years of my various permie jobs. It's easier to just be honest.
If they're ageist, as many are, then you can't lie or BS your way past that.
