Lots of people get through engineering school but are terrible engineers. Interviews are important (and difficult... Not many people are good interviewers!)

Colleges aren't all equal.

Professional certifications are different

Professional certifications have a terrible reputation for good reason. You are perhaps too young to know why this is a silly idea. But its been tried and it failed spectacularly.

It works in essentially every other profession. Programming isn’t that special.

In essentially every other profession the credential is gated behind years of work experience and often a degree or course.

We already have such a credential. It's called "lasting two years at a FAANG+ without getting fired". If you do that you can get interviews anywhere.

It appears that the coding job will be some variation will be some variation of vibecoding going forward, so a professional cert might be good enough.

I have an example of a certification that is useful in my first comment...
