The interviewer wants to know that you are confident about your leadership abilities and that you understand when your leadership abilities have been most effective.
Perhaps you best demonstrate yourself as a leader when your manager is away. Maybe you often jump into a leadership mindset when a co-worker is struggling. Think about a recent time when an employee on your team was successful at something because of your leadership skills. Discuss the scenario and how your leadership skills made the difference.
"I best demonstrate myself as a leader when I know that a coworker could use my assistance. I seem to be a natural teacher and mentor which means that when someone is struggling, my first instinct is to train them. Just recently, I coached a new employee on a sales technique that helped her to achieve her quota for the first time. I look forward to working in this role with you because it will allow me to take on further leadership opportunities."
"In my current position, every time my current manager is away, I take on the role of leader for our team. This is usually one day per week. When you call him for a reference he will be able to tell you that I have naturally stepped into the responsibilities associated with being a leader."
"I am a leader every day and anytime I am in the presence of subordinates, be it a picnic, in the parking lot, or during the workday. I always exude my leadership attributes."
Sales answer example
"I think it's important to always be a leader. The old cliche of "dress for the job you want, not the one you have" applies here. From the get go, I think it's important to walk in the door letting your supervisors know that you are ambitious and driven for growth and also let your coworkers and reports know that you're here to grow and help them grow, too.
Leadership in micro-moments is one of my favorites. That is, taking a new hire out to coffee, even if it's not your job is really great leadership. Letting someone feel welcomed into the fold and teaching them the ropes is so important, especially in the often competitive environment like a sales floor."
Marketing answer example
"I feel as though I rise to the occasion whenever it presents itself, whether that's by stepping into a leadership role in a collaborative cross-department project, when my boss is away, or when a new hire is wide-eyed and without direction. Basically, whenever the group is lacking a leader, I love the opportunity to step in and help the team along with a bit of an opportunity to shine."
