In the military we staged "tests" when we deliberately made sure that things did not go according to plan. We made those things happen in ways that the candidate was unaware of. We deliberately set guys up to fail, starting with getting them pissed the night before, then feeding them bullsh1te, then telling them to work with troops who were in on the joke.
Wow, glad I gave the military a wide burth.... At least the instructors we have try to get us through to the end...
