The interviewer would like to hear you tell a story about a time when you had to undertake an unusual customer service challenge. Avoid speaking negatively about any customers, supervisors, or past employers. Stick to facts such as what the problem was, what action steps you took to ensure your success, and what the result was in the end.
Since this question is a 'Tell me about a time' query, try to approach your response using the STAR method, which is Situation, Task, Action, Result. This framework will keep your story on track and ensure that you provide the details that an interviewer will need to assess you in this behavioral-based question.
