As a Criminal Investigator, it's essential that you can read others, either while questioning and interrogating, or even in a simple everyday interaction. If you are interviewing the suspect of a crime, for instance, you should be able to identify specific behavioral markers associated with lying. If you have a background in law, criminology, or psychology, you will likely have formal training in how to spot these incidences. Talk to the interviewer about what you look for in these types of instances.
"As a seasoned Investigator, I understand the importance of behavioral anomalies, and what they mean. I look for a series of both verbal and nonverbal signs to determine if they align well with what the person is saying. In an investigation, I will look for exaggerated facial movements, wringing of the hands, lack of eye contact, and accuracy of facts for starters. If I sense an irregularity in facts, I will dig deeper into that topic to see if the person starts to give contradicting information."
"I learned a lot about indicators, during my criminal psychology coursework, and a bit about nonverbal behaviors. A lot of emotions are communicated through facial expressions and the tone of voice, as well as gestures. Often, people under stress attempt to hide their feelings, and then they begin to express themselves differently with nonverbal behaviors. I plan to look carefully for signals such as over-blinking, speech rates, and active attempts to regulate emotions unnaturally."
