Actually, my first programming job ever was in MUMPS! It was only for
the summer though.

The language certainly was weird. In one way it was very high-level: you
did not have to open files and that. Just put a ^ in front of a variable
name, and it was on disk. (I did not knew what a "database" was then.)
On the other hand, some stuff were low-level, for instance the syntax
did not permit indentation.

The most weird thing I did was to implement some search-and-replace
utility. This was not a regular program, but it resided in a global
array (global = on disk). I found that this brought me to the low
level that I did not any more have the luxury of a program counter,
but at the end of each row, I had to explicitly say which "line" to
go to next.

I'm surprised to see that it still around.
