Final answer:
When an interviewer doesn't understand a response, they should observe the client's body language and cues to gain a deeper understanding.
Step-by-step explanation:
When an interviewer does not understand the meaning of a response that a client has made, they should take note of the client's body language and cues. By observing visual cues such as eye contact, fidgeting, and facial expressions, the interviewer may be able to infer the client's true intentions or level of interest. Additionally, the interviewer should reflect on the client's tone, emphasis, and emotional state to gain a deeper understanding of their response. By considering both verbal and nonverbal cues, the interviewer can better comprehend the client's intended meaning.
