Huh. That is an interesting point about carpentry not being as easy to self-teach. I don't think it's entirely impossible to do so, the Youtuber Mr. Chickadee being a counter-example: he's mentioned in interviews learning techniques from books, such as Japanese joinery.
But then if you watch channels like Essential Craftsman it's clear there's a great deal of know-how that has to be passed on by someone who knows the trade. Stuff about how to work efficiently and tricks you wouldn't think of. Even if it were in a book or videos exist, you don't necessarily know to go looking for it.
It is definitely possible to self-teach auto repair. I did, out of necessity. Things you try either work or they don't, but there's logical reasons for it that can be derived from first principles.
However the computer is in a class of its own when it comes to self-teaching. Instant feedback and infinite capacity for experimentation. Carpentry doesn't have a built-in objective critic like that. Auto-repair is somewhere in between.
You'll pass their "do you already know carpentry" test by being able to demonstrate basic safety knowledge and knowing which tool is which. You can definitely teach yourself carpentry, and they are likely selective because they have people coming in who have already self-taught a fair amount. So if you come in not knowing what a screwdriver or a drill bit is, they don't want you.
It would be unreasonable if they expected something like experience with specialty MDF blades and full panel saws. I doubt that is really what they wanted.
