If you get an interview through a recruiting company, make sure you call them, on the phone, in person, and get as much detail on the job as humanly possible. I just had an interview today that lasted five minutes, two of which were the guy expressing his disappointment that I didn't know enough about the position being offered (screw you, dude, I have had 80 interviews in the last two months. Your BS customer service gig is barely worth the brain power).
