Royal Mail's dedicated Information Security awareness programme says, "Think Secure. Be Secure. Be Positive. Don't be a rule breaker, make sure you follow Royal Mail's policies and procedures. Oversharing is not caring for Royal Mail. Oversharing of information can result in identity theft, crime against individuals and businesses that also can lead to brand and reputational damage. Be Positive, because it leads to better things, faster. We love to give it a go, aiming to make life better and brighter for our customers and each other. We trust each other to do the right thing and always say thank you for a job well done."

Your interviewer wants to know how far you go to protect your customers' and your employer's information and whether your conduct exemplifies the integrity they look for in their ideal candidates. Spend time learning all you can about their approach to this topic, and pay attention to the language they use. "We are all responsible for ensuring that personal information is kept secure, with due care and respect." The goal here is to answer this question like you are already one of them.
