More employers than you would think. The professional certs are legit. Also, 50% of some cloud native DevOps and infrastructure engineering roles are covered by the pro certs.
(Nobody cares about SWF.)
Except for button-pusher roles I've always hired for whys, not hows, and certification programs seem to never care about the whys. College degrees don't assert that you know how to learn, that you know how to derive the whys--but, in my experience, they correlate better than cert-hunting does.
