> Do you have any regrets in your Job?

I don't know if this is the correct answer, but often a question like this feels like, to me, a question of intent and growth.

A quick google define of Regret is:
> feel sad, repentant, or disappointed over (something that has happened or been done, especially a loss or missed opportunity).

What I do now is ask:
> What **purpose** does regret serve?

To educate us.

Thus, when someone asks me what I regret, I have essentially a response that demonstrates, a missed opportunity or error, how I handled it, **and this is important**, how I **grew as a professional from it**, how has it changes me and my perspective. How has that experience made me better.

Maybe I'm wrong, but I think that's the intent of the question. Have you missed an opportunity or made a mistake and have you grown from it.

UPDATE:

Additional thought, Regret also serves as a way of thinking about ownership or responsibility. Have you ever failed in a moment on a task that you had ownership or responsibility of? Regret would be the result, because it MATTERED to you. It shows you cared or were at least conscientious towards your work.

If you didn't care, then you wouldn't experience regret.

I might absolutely be over-reading it. But I definitely think that sort of question is about failure and growth more than anything.
