In a culture that often celebrates success and hides failure, this question can feel like a trap. It can induce a moment of panic.
Your instinct might be to minimize, deflect, or present a "fake" failure. But the truth is, this question is not a trap. It is an invitation. It's an invitation to demonstrate humility, self-awareness, and your capacity for growth—three of the most sought-after traits in any professional.
