Top 10 Questions for Polygraph Examiner Interview

1. Explain the different types of polygraph tests and their respective applications.

A polygraph test, also known as a lie detector test, is a device that measures and records several physiological responses such as blood pressure, heart rate, breathing rate, and skin conductance. There are two main types of polygraph tests:

• Control Question Test (CQT): This is the most common type of polygraph test. It typically involves asking a series of questions that are relevant to the investigation, as well as a series of control questions that are designed to elicit a truthful response. The examiner then compares the physiological responses to the control questions with the responses to the relevant questions to determine if the subject is being deceptive.
• Guilty Knowledge Test (GKT): This type of polygraph test is used to determine whether a subject has knowledge of specific information that is not publicly available. The examiner asks the subject a series of questions about the information, and the subject’s physiological responses are recorded. The examiner then compares the subject’s responses to the questions about the information with their responses to control questions to determine if the subject has knowledge of the information.

2. How do you interpret polygraph results?

Factors to Consider

• The type of polygraph test that was administered
• The physiological responses that were recorded
• The subject’s demeanor and behavior during the test
• The subject’s history and background

General Interpretation Guidelines

• Inconclusive: The results of the polygraph test are inconclusive if the examiner is unable to determine whether the subject is being deceptive or truthful.
• Deception Indicated: The results of the polygraph test indicate that the subject is likely being deceptive.
• No Deception Indicated: The results of the polygraph test indicate that the subject is likely being truthful.

3. What are the limitations of polygraph tests?

Polygraph tests are not 100% accurate and there are a number of factors that can affect the results of a polygraph test, including:

• The skill and experience of the examiner
• The subject’s physical and mental health
• The subject’s ability to control their physiological responses
• The use of countermeasures by the subject

4. What are the ethical considerations of using polygraph tests?

There are a number of ethical considerations that must be taken into account when using polygraph tests, including:

• The right to privacy
• The potential for false positives and false negatives
• The use of polygraph tests in employment and other settings
• The potential for polygraph tests to be used to coerce confessions

5. What is your experience with conducting polygraph tests?

I have been conducting polygraph tests for the past 5 years. During that time, I have conducted over 1,000 polygraph tests in a variety of settings, including pre-employment screening, criminal investigations, and civil litigation.

6. What is your success rate in detecting deception?

My success rate in detecting deception is approximately 95%. This is based on the results of a number of studies that have been conducted on the accuracy of polygraph tests.

7. How do you handle cases where the subject is uncooperative or attempts to use countermeasures?

In cases where the subject is uncooperative or attempts to use countermeasures, I will typically try to establish a rapport with the subject and explain the purpose of the test. I will also try to address any concerns that the subject may have about the test. If the subject continues to be uncooperative or attempts to use countermeasures, I may terminate the test.

8. What are your thoughts on the use of polygraph tests in employment screening?

I believe that polygraph tests can be a valuable tool in employment screening. However, I also believe that polygraph tests should only be used in conjunction with other screening methods, such as background checks and interviews. I also believe that polygraph tests should only be used for specific positions that require a high level of trust and integrity.

9. What are your thoughts on the use of polygraph tests in criminal investigations?

I believe that polygraph tests can be a valuable tool in criminal investigations. However, I also believe that polygraph tests should only be used in conjunction with other investigative techniques, such as interviews and evidence analysis. I also believe that polygraph tests should only be used in cases where there is a strong suspicion of deception.

10. What are your thoughts on the future of polygraph testing?

I believe that polygraph testing will continue to play an important role in law enforcement and other fields. However, I also believe that there is a need for continued research on the accuracy and reliability of polygraph tests. I also believe that there is a need for the development of new and improved polygraph techniques.

Polygraph Examiners play a critical role in law enforcement and security by utilizing lie detection techniques to verify the truthfulness of individuals.
