This question evaluates your confidence and self-awareness and offers a chance to revisit questions you wish you could have answered differently. Avoid picking your interview apart or talking down on yourself. Self-deprecation won't serve you well, nor will asking them how they think you've done. Instead, that will suggest you aren't self-aware or are too insecure. Confidence in your abilities is the aim here. Don't waste any opportunity to succeed. Exhibit a thorough work ethic by seizing this opportunity for a second chance to revise your answers.
