QuoteIT IS A WASTE OF YOUR TIME to worry about what may or may not be the control or relevant questions until the examiner goes over the question they will ask you right before the test. Worry about distinguishing between the two as the examiner reviews the test questions right before the test. Worrying about them before this period of time is a waste of time...if anything, get some ideas as to what they will turn into control questions.
Quote4)If they administer a post-test interrogation/interview, NEVER fall into their game and admit to anything MORE than what you told them. You will be canned right then and there if you do. They might try and intimidate you--even if they suspect you passed--just to get you to blow it and make a damaging admission.
5)Never admit to using countermeasures EVER or even knowing about how the polygraph works. You will get booted if you admit to using countermeasures. If they ask you if you know how it works, respond by saying, "Yeah I heard it buzzes if the machine knows someones lying." Come up with a good response.
