Okay so I'm lazy and only read the original post. BUT . . .
I am a big anti-IFer, always have been, BUT when I was between jobs I was going for ANYTHING and EVERYTHING and I even interviewed at IF. They actually really liked me, up until they told me that they drug tested. Now, I don't do drugs, never have, never will. And at that time I had also never worked for a company that did drug testing. So out of just SHEER curiosity I asked if the drug testing was a one time thing, or something they did on a regular basis while you are employed for the company. The mood of the interview quickly turned sour after that.
Note to self, don't ask questions about drug testing. It makes you appear like an addict. OOPS!
