Her entire story is a good one.
So you should read her whole post.
My favorite part, though, is this realization:
After three years of PM’ing at a big company and a startup, I’ve realized that those passions I stated during my first product management interview — deeply understanding other humans, removing pain from people’s lives, writing, field-research, finding patterns and trends in data, designing for humans — were exactly what my interviewers were looking for, because that’s what it takes to be a successful PM.
When you boil product management down to its essence, that’s what this discipline is really about. If only she had included something about Xena, it would’ve been perfect 😉
