By fail I mean denied employment based on polygraph results. Everyone I know, 5 or 6 people, was disqualified on technicalities or odd anomalies such as the stories quoted below. Two of them were for irregular breathing patterns that made it difficult for the polygraph administrator to determine accurate results. Another for no change in breathing pattern or heart rate when given test questions that were to determine what happens when he lied, and was accused of trying to skew the results by practicing how to pass a poly in their own time. It makes no sense, but it apparently happened. Their answers on the poly all matched what they disclosed on their application packet/background check questionnaire. All previously held a secret or TS/SCI clearance in the past (I worked with most of these people at the Presidential Helicopter Squadron, HMX-1). Seems like the system is failing the border patrol of qualified applicants, not helping them gain them.
