With these kind of things I don't think asking questions is really going to tell you much.

People can present themselves differently than they are, and especially people with lower morales will have no problem presenting themselves differently if that is in their interest. Look at pretty much any big company CEO.

If you do need to gauge someone, look at their history, look at their actions, and look at their incentives. If they don't align with what they're saying you should not expect them to act any different than they did before.
