I think that's an interpretation that wasn't necessary (though I agree they're terrible and risky interview questions). I'd stick to hard challenges is my professional life, hard problems I had to solve, etc. My personal life is none of their business.
And I think there's the possibility you may have been rejected for sharing too much. But I agree that kind of question does invite sharing too much.
Not the OP, but having been in many similar interviews, I feel like it's an easy trap to fall into, especially if you've not developed a good bit of curmudgeonly cynicism.
At least when I've done these interviews, they will be extremely friendly, and they will at least act interested in everything you have to say. It's very easy to overshare when you think the audience is actually interested in what you have to say.
I'm an oversharer, so I'm absolutely vulnerable to that trap. It's important to remind ourselves not to fall for it.
