The funny thing is, most universities are accredited institutions in their own country. Which means that whoever gets their diploma is accredited too to work in any company in the field of their accreditation.
And this is the norm in many industries to signal your competence (plus the renewal in every X years).
Would you ask a surgeon to do a surgery before you hire him? So why do we put up with all this bullshit that low-IQ HR departments impose on us?
I would rather take the effort to pass accreditation each X years and then let me join a company with a simplified process (background check, personal interview, etc), than putting effort into practicing before each and every interview.
