SNOWDEN: CIA/Booz Allen Hamilton/Carlyle Group/Dell/NSA
According to this article Snowden's Resume was filled with lies

For example, NSA security officials failed to conduct a routine check of Snowden's educational background. Had they done so, NSA would have learned that Snowden had dropped out of high school in his sophomore year, yet falsely stated on his resume he had graduated from "Maryland High School" in 2001. There is no high school in Maryland with that name.
Snowden also was granted a "top secret" security clearance in 2005 despite an associate warning security investigators he should not be given access to secrets.
Snowden was hired as a computer technician by a CIA contractor and converted to CIA employment in 2006 after obtaining a security clearance. While at CIA, he complained of harassment by a supervisor.
He was posted overseas, but was relieved of his position after altering CIA software improperly and disobeying orders.
Snowden then applied for work at NSA and was hired by an NSA contractor in 2009. However, the report revealed that CIA failed to update a security database with derogatory information about Snowden. As a result, NSA failed to learn of his problems at CIA before hiring him.
The Office of Personnel Management updated Snowden's security clearance in 2011 with an investigation later found to have been incomplete.
"Among other flaws, the investigation never attempted to verify Snowden's CIA employment or speak to his CIA supervisors, nor did it attempt to independently verify Snowden's self-report of a past security violation—areas where further information could have alerted NSA to CIA's concerns," the report said.
Investigators also failed to check job references on Snowden beyond those he offered: his mother and girlfriend.
No background check for Snowden–means he was already Deep State Operative. Russian Agent?
