I sent a cold letter of inquiry re freelance work to a publishing company in NoVA, after seeing a craigslist post for a managing editor position (I think that's what it was; in any case it mentioned managing freelancers). I got a response today, with an 8-page editing test. Among the instructions was this:
"3. Please supply a document-specific style sheet; it should show (1) a list of specific vocabulary terms and word spellings/usage particular to this document; (2) conventions for number usage; (3) acronyms used in the document; (4) hyphenation usage (specific hyphenated terms) in this chapter; (5) special symbols used, if any; and (5) a query list (referencing the approximate line number where the query occurs within your edited file)."
I don't think so.
