In a Craigslist post by Publications Professionals LLC in Fairfax, VA:
"ALL candidates must successfully complete a 3-hour-long battery of tests of their English-language, editorial, and proofreading skills."
I passed PP's test in 2002, which led to a temp-to-perm position. I was hired after three months, worked at that company until 2007, and then quit in a huff over my nonsensical reassignment driven by politics. I evidently have been blacklisted by PP ever since; my many inquiries re temp work have been fruitless.
