I get what you're trying to say, but to put it simply when grouping terms you tend to list adjectives in alphabetical order.
So "User Experience - User Interface" would be correct as full terms, however as initialisms, it's written UI-UX. I'm just being pedantic though.
I got your point. Isn't designers are pedantic, always have an eye for details. :)
Yep, and I totally agree :)
Because if you put UX first recruiters pay you twice as much as if you put UI first.
