Describe a situation where a customer reacted very negatively towards you in an interaction. How did you handle that situation?

At some point in your career in customer service, you've likely had a customer become negative, angry, or even hostile. With this question, your interviewer is looking to hear that you can handle this type of situation with ease. Let them know that despite the negative reaction, you took the necessary steps to turn a potentially bad situation into a positive outcome through a positive attitude and diligent effort. Everybody has bad days; what's important is the way you react to the problem.
