Good writeup of what happens in an FBI pre-employment polygraph: https://www.andrewwatters.com/hall-of-shame/FBI-SACU/FSL/pol...

Dang so this is much more comprehensive than a normal polygraph. I know the write up says it would be almost impossible to beat, but is that true?

Well the FBI prosecuted a guy who provided training on how to beat it.

		Indeed, the FBI participated in the criminal investigation of the late Doug Williams, who offered training on how to pass or beat a polygraph "test." Because there was no actual crime for which to prosecute him, federal agents set out to stage one in a "sting" operation they dubbed "Operation Lie Busters": https://antipolygraph.org/blog/2016/04/26/operation-lie-bust...

		Yes, the polygraph has one purpose, instill fear. It's an over the top interrogation. Level 1 torture.
