Tell me about any customer service training you have received.

G4S knows that exceptional security services are all about customer service and the level of service they provide to each of their valued clients.

Walk the interviewer through any formal customer service training you have received in the past. Maybe you have worked in retail, or hospitality where you received on-the-job training on how to relate to a customer, be helpful, properly greet people, or diffuse conflict. Maybe you have trained yourself by reading books on the subject, listening to podcasts, or reading articles online.

As well trained as you may be, it's also essential that you show the interviewer your continued interest in bettering your customer service delivery. If you are not sure about the training you will receive with G4S, you can ask for specifics.
