Developer interviews are different than most other places, because not only do you worry about the people you work with, benefits, job description, etc., you also have EXTRA to worry about after getting the job. Writing two application with exact requirements can be vastly different if you're working in a loud vs quiet environment, using VS2003/.NET 2.0 vs VS210/.NET 4.0., using SVN vs VSS. Is it ok to give the potential employer the straight-up Joel Test? I try to ask as many questions to get the type of environment I will be working in, which is extremely important from my perspective, but what's the best way to cut to the chase and just ask the tough questions (like they ask you during the same interview).
NOTE: By the "Joel Test" I mean a specific list of things that are deal breakers that are important to you (not necessarily Joel), but you may not have time to get out using the traditional casual "conversational" way of asking them, so you decide to either email or schedule another meeting, or ask other people, etc.
