His first application to join TAO as a remote operator was denied due to personality conflicts (the interviewers felt he was cocky in his responses and weren't sure of his ability to fit in with the rest of the operators.) This was circa 2011 when he was working with the CIA in an NSA joint Billet.
Early 2012 during expansion and hiring within TAO Hawaii, he was given a second chance to prove technical talents in a test designed to pre-empt RIOT (Remote Interactive Operator Training). He failed the test twice both at NSAH and NSAW. His only option was to transition as a contractor at BAH where he was the equivalent of an R&T analyst even though he was in a network administration billet(he was never assigned to TAO directly, because his administration billet supported missions he was asked to fill a critical shortage of manpower). The technical requirements to become an R&T analyst while high, were well below those that perform as Interactive On Net operators (ION). As an analyst he worked projects targeting the exact groups he leaked information about. During his time working his targets he submitted numerous plans that were rejected and greater HQ at NSAW began to ignore is operations proposals. His projects were ultimately removed from him and placed in the hands of capable analysts. It wasn't long after that he decided to lash out. So no he was never offered a job within TAO (which has multiple groups), when he did work with BAH interacting with them he failed miserably.
