The joke is really on the employer using Facebook ads to target a younger candidate pool.
Youngsters don’t use Facebook. And if a young dev is using Facebook - they’re certainly using an ad-blocker. If they’re not using an ad blocker on Facebook, do you even want to hire them?
Seems like if you wanted to attract a pool of young candidates now days, you’d target the parents of the said youngsters. The ones with no applicable experience, and who are still living at home “looking for a job.”
The ad should be to the effect of “tired of your good for nothing millennial taking up your third bedroom? Want them to move out? We’re hiring good for nothing straight out of college devs so as to lock them into a low tier pay bracket.”
