I should think not! It's been about 30 years since I've last needed to 
reverse a linked list (in Pascal, not C, but the principle is the same). 
Who does that these days?

I would have *no idea* how to traverse a singly-linked list in reverse 
without making a copy of it first.

Okay, if you're specifically looking for somebody to write low-level 
algorithmic code, that's one thing. But 95% of programmers spend 95% of 
their time using library calls. And the remaining time, they certainly 
don't have to come up with a "reverse this linked list" algorithm from 
scratch. Google it, or look it up in a book.
