Does anyone have any stories of an applicant filling out the SF86 and then getting rejected BEFORE taking the polygraph?  It seems like all of the stories here are post-poly rejection.

Could a government agency decide in advance that a candidate will be rejected just based on their SF86 alone, but yet the government decides to polygraph the candidate anyway just for "practice?"  Maybe so new polygraphers get practice and also to see if they can extract some sort of criminal confession from the applicant, who will be rejected anyway no matter what.

Do these scenarios happen?
