Look, I've been on interviews where you are confronted with uncomfotable siutuations just to judge your reaction and how you process the information. That is a classic Wall Street investment banking interview technique. What Ireland did was waaay over the line. If he worked for a regular company, he would be sued and likely fired or at least reprimanded. That question is completely unacceptable. It is not a behavior question or even a fair response question.
Anyone defending it...why don't you ask it the next time you are interviewing someone and see how far it gets you...hell, your company is making an investment in the person, gotta know that person's background right? Tell me how many hours it takes for you to get fired, I set the O/U at 4.
