Thanks for the link to this. The full report (PDF) makes for interesting reading:

Another check airman at Mesa said the FO’s stick and rudder skills were weak, and he also struggled with basic flight management system tasks. This check airman described the FO’s piloting performance as among the worst he had ever seen and noted that the FO tended to have an excuse for each of his poor performances, such as blaming his simulator partner, his instructor, or the hotel. A third check airman at Mesa said that the FO had weak situational awareness, did not realize what was going on with the airplane at times, and had difficulty staying ahead of the airplane. She said the FO was completely unaware that he lacked skills, unwilling to accept feedback, and unhappy with her about his failure to upgrade to captain.
An instructor who taught cockpit procedures on the flight training devices at Air Wisconsin Airlines recalled that during one emergency procedures training scenario, the FO made abrupt control inputs that triggered the stick shaker and overspeed alerts. The instructor said that instead of staying engaged in the scenario and addressing the problem with his training partner, the FO just stopped what he was doing and turned around and looked at the instructor. The instructor found this reaction highly unusual.
Turns out Amazon didn't know about any of these failures, because here's your government in action (inaction):
Ten years ago, Section 203 of the Airline Safety and Federal Aviation Administration Extension Act of 2010 mandated that the FAA create an electronic pilot records database (PRD), which was intended to improve the timeliness and efficiency of the PRIA records retrieval process by providing hiring operators and DAs with direct access to pilots’ FAA, NDR, and former employer records in a single database. By 2016, the FAA had not yet implemented the PRD, and Congress imposed an April 30, 2017, deadline, which the FAA also missed. Although the FAA has begun phasing in the use of the PRD, the PRD is not yet fully functional; it contains only pilots’ FAA records and is available to hiring operators for use on a voluntary basis.
