The interview question I find most enlightening is: 

“What core values guide your decisions, and what's an example of a time they were strained?”

“How did you navigate that tension?”

Silence is the most revealing answer.

I do like this line of question but it feels like a better async ask, because I would bet you could learn more about someone if you give them the chance for introspection on their own terms.

We all process and think differently, sometimes questions like this might ostracize a quality candidate
