Not only does this question test your desire to grow, but it assesses your self-awareness, your determination to succeed, and your emotional intelligence. Some may fear that revealing their weakness will make them look ill-equipped or small. But it's important to cast away such insecurities. Admitting to your weaknesses and viewing them as growth opportunities demonstrates greater strength than not admitting them. There's an old expression, 'No one can hold over you what you already own.' So own up to it and let them know how they can help you overcome this area you'd like to develop, personally or professionally. Share the action plan in place for improving this weakness, and ask how they would recommend improving upon your strategy. The road to self-improvement is never-ending, and you'll convince them of your determination to succeed by sharing your plan.
