9 times out of 10 the job description you get from the recruiter is a lazy cut-and-paste from the actual company's input.
It's never anonymized and simply pasting it into Google will almost always get you a lead on the hiring company.
Another lead is if they give you the company location. There is only one company on the planet, for example, that has R&D offices in both Mossvile and Aurora, Illinois.
Also 9 times out of 10 its a bait and switch for a different company. Whenever I've worked with these recruiters they always "see whats a good fit" with my resume and its never the company that was in the job description.
