Both of those links come from that same person, tracewoodgrains, who links the documents on their google drive. Looking through the documents, it appears there was a case that happened in 2014, which was investigated in 2016. They found an FAA employee in a New York state office held a teleconference about how to apply to the open positions. People asked him questions and he answered them. The investigate was closed noting the following:

"OIG reviewed official government emails for the period January 2013 to July 2015 and did not identify any additional matters or information of specific interest to this investigation.

AEO-500’s ROI Case Number AHQ20150170 did not develop information that demonstrated HR employees gave improper advantages in processing the applications of ATCS candidates affiliated with the NBCFAE. A review of the ROI did not identify any issues that warranted additional review in this investigation.

The findings in this investigation did not warrant a referral to a federal prosecutor."

What exactly makes 'diverse' candidates more likely to answer 'science' and then 'history' on those questions? Are you saying there was a conspiracy to create hard to answer questions on the test and then give out the answers to diversity candidates?

Occam's razor says this was a bullshit 'behavioral' test that meant nothing but disqualified a lot of candidates, and someone who knew that gave others a way to bypass it to get their foot in the door in one instance.
