The thing is, they are treacherous with their questions. Because the question itself doesn't matter, what you answer is not the question itself, but the hidden question behind.

This means they don't trust you to answer honestly, and yet, once you know how the process goes, they actually encourage people to be treacherous too.

This is a lose-lose strategy that they're using. They are selecting treacherous people instead of qualified people. Probably because they are not qualified themselves, and because qualifications don't matter to most companies. What matters is appearances and selling an idea.
