Curiosity shows a desire to question with the intention of improving something, and identifying weakness paves the way to reflection and improvement. Both are key qualities that when employees posses them can drive a business to succeed. Measuring and testing them at interview can be challenging for the interviewer, but if you feel you possess these qualities, demonstrating them at interview with examples is a good way to evidence them. Looking up your interviewer and the company on sites such as LinkedIn is a great place to start.
If you are curious, you'll continue to learn. If you identify weakness, you'll already be closer to overcoming it and these are certainly ingredients for success.
Successful teams are not afraid to adapt. They are not fearful of finding their own weaknesses, for that is how to address them. Psychologically, however, it is difficult to engage with our failings, because we like to think of ourselves as smart and competent. One has to flip this perspective to unleash the curiosity that is the hallmark of the greatest individuals and institutions.
