My overall experience was generally positive as I completed a CI polygraph recently at a government intelligence facility.  The one thing that surprised me is that I was accused of "using countermeasures."  I didn't even know what countermeasures were until I looked them up after I arrived home.  Before the test, I was advised to be aware of my breathing. As a result, I tried to be aware of my breathing and take even breaths during each question.  After the first test, I was advised to "do myself a favor" and breathe normally.  I was a little shocked as I was supposed to be "aware" of my breathing.  At the end of the testing, the examiner informed me that he knew that I had deployed "countermeasures" but that I had eventually passed after ignoring my breathing patterns.  To all polygraph examiners that may be reading this thread - NOT ALL applicants are using "countermeasures" especially after we are directed to be aware of our breathing. It is unfortunate that the examiner believes this about me... and that it is a matter of record at the agency (and is likely in the examiner's report).  I love my country... and the allegation about the "countermeasures" simply isn't true about my exam.
