Even a skills-based test like welding, you do run up against a limited number of real standards, unlike coding interviews. What materials are you joining, measurements, what process are you using, do we have particular requirements about penetration, non-destructive test results, tensile strength, etc etc. That's the problem with modern development not having a central certification or licensure or a standards board/bar, everyone tests something different even if they think they're testing the same thing and it's a depressing mess.
