"he setup is simple for this crash course, and (we'll
consider ourselves the teachers) you should let the student know
that they're in for a fun little piece of problem solving. Maybe,
if I had the time to give this some more thought, it could be a
pretty decent (although probably unusually cruel ;) interview
tactic. If you have the time (and the stomach) to do that to some
poor bastard that's looking to make a buck; go for it. I'm a pretty
harsh interview, but I don't know if this is something I'd do to
someone who didn't already know that their future employment was
ensured (pending the outcome of drug testing, of course. Quite
frankly, if you don't have what it takes to do your job while
you're loaded to the gills, I don't think you'll not be able to see
right through my fragile mask of sanity ;)"
