In my experience as an interviewer, I would like to see a number of
a) Solution to an interesting, non-trivial problem
b) Follows a minimal set of best practices (use strict & warnings,
appropriately modularized for the size of the problem, avoids common
c) Well documented (might include an external explanation of what the
heck this is for)
d) Readable / Maintainable (admittedly somewhat subjective)
e) if you included unit tests, you would win big points from me

That's certainly a false assumption. If I could hire someone I
thought was equal in skill-level to myself, I'd do it in a minute.
(And, doesn't this complain apply to all interview processes?)

Yes, all of the above.

This is a good reason to release at least some of your code as open

Some might say that abstracting that sort of thing out into a
configuration system of some type would be good software engineering

Well, if it's too big, they aren't really going to look at it. I'd
ask them what size program they are looking for. Personally, I'd aim
for less than 500 lines, but still non-trivial.
