Your interviewer might ask you a question that catches you off-guard, like asking what you dislike about your job. This is a way for them to see how you respond to difficult topics and react under unexpected pressure, which will be key in your role in a call center. Prior to your interview, practice a series of questions with a friend or record yourself so you can collect feedback on how you respond. Know that an interviewer can always throw in an unexpected question, so focus some of your practice on how you react, not just on what you say. Remember that, overall, you want to keep the tone of your interview positive.
