Interviewers ask this question to determine how quickly you act on your feet and how well you react when things don't go according to plan. How you answer will also potentially reveal your emotional intelligence. It's the difference between feeling overwhelmed and experiencing task paralysis or the ability to navigate your stress and emotions, be resourceful, and do what needs to be done swiftly, holding the interests of your teams above your own. As one of Klarna's founders and CEO, Sebastian Siemiatkowski, once said, "Every hour lost on discussing what we should be doing, planning, theorizing... Instead of actually doing, testing, iterating, and learning. That's the difference between a startup and a big company. Between success and failure."
