The algorithm will contrast your answer against the confidence and conviction behind your statements. Before the interview, research the body language of a confident and relaxed person in a seated position. Pump yourself up with physical exercise to manifest confidence. Raise your arms, stretch your back, and make yourself as big as possible. Look yourself in the eye and say some self-affirmations or give yourself a pep talk. Doing so will help you match your demeanor with your self-qualifying statements.
