One examiner who tells callers that he is "the best polygraph examiner in the nation" also lists on his resume that he was the 'technical consultant' for a specific law enforcement TV drama.
However, the TV show that interviewed him for that possible assignment also interviewed another examiner the next day; the TV show chose to use the other examiner instead.
The self-proclaimed 'best examiner in the nation' was never hired by the TV show. The TV show never paid him a cent. They never brought him on set.
The TV show chose his competitor after the same TV team had interviewed both. The competitor did the assignment (an episode that involved polygraph) on set and was paid.
If one listing on a resume' is a lie, that squashes the credibility of anything else listed on the resume'.
