It's your time to shine when you talk about your achievements. Make sure you're preparing ahead of time for this question.
Write down three possible past wins relevant to the company and position you're applying to, and practice articulating your answers. Do your best to be specific and possibly throw in numbers to really back up your answers. For example, saying something like, "As a result of achievement X, revenue numbers increased by X percent year over year." This will really show your hiring manager how you added value to your past company's growth and reveal your worth as an employee.
