Tell me about your experience in customer service. What did you enjoy most about it? What were the biggest challenges? How would you handle an upset customer who feels they have not received good service? How do you typically deal with stressful situations when multiple customers are making demands at the same time? When you're faced with an angry customer, how do you turn the interaction around into a positive experience? How would you handle a customer complaint about a product or service you feel is unfair?
