Basically I goad them into complaining about past bad work experiences and then pay close attention for subtle clues that may indicate that they are systemically disrespectful or unwilling to compromise on things that don't seem worth fighting for. Were they bothered by people, situations or outcomes?
Tell me about the most frustrating time when you needed a thing, or consensus on a thing, and you had to go through way too much to get it.

And, of course: The fastest way to be shown the door around here is to be an agitator of your colleagues on the grounds of race, sex, religion or any other attribute that has little to do with work. Nobody here is in the business of policing behavior and nobody wants to be. This requires perhaps more discipline than other places as the hammer falls harder and quicker here if things go awry, so it demands either heightened discretion or a heightened sense of self awareness and awareness of those around you. Do you think you would be able to work under such conditions?
