Watch for these interview body language signals from your interviewer to read the message they are sending you.
Body language cues that can indicate boredom include resting head on hand, fiddling with hands and losing eye contact. If this happens wrap up what you are saying and move on by asking the interviewer a question such as:
"Is there anything else you would like to know about that topic?"
Drumming fingers and rubbing the face can indicate irritation. Clarify that you are answering the question with the information they want and not frustrating them with an off-the-point response.
