Interviewers want to hear that you are determined to overcome any challenge that comes your way! What was the last challenging goal you had to achieve at work? Explain the goal at a high level. Share who assigned you the goal, and explain your initial reaction saying, "This might be hard, and I can do this!" Tell the interviewer that you immediately got to work jotting down a plan for how to conquer the goal. Define why the goal was challenging for you, and explain the great plan you came up with to overcome the challenge. Finally, re-iterate that your desire is to conquer your challenges with a positive outlook.
