"I grew up playing sports and a competitive drive was instilled in me by my parents from a pretty young age. I learned the values of teamwork, preparation, and practice from my years playing competitive hockey, golf, and baseball and these are values I'm so excited to bring to your pharmaceutical sales team. While I fully plan to know and master the line of drugs I will be working with, I feel it's also equally important to know my competition and I will work hard to have a full grasp of what I'm in the market against on a daily basis in this role. I look forward to achieving big things with your company and working hard as a team to do so."

First, make sure to give a resounding "yes" to the fact that you are a competitive person, both in your personal life and on the job. Then discuss ways you have proven your competitiveness and your ability to win in a fair and respectful manner. Some things you want to highlight are your ability to work as a team to provide great results and how you like to celebrate successes. You can certainly give examples of your love for competing in both your personal and professional life.
