Human Factors
My co-worker [and I] were taking a line check with a representative from the FAA on board. The initial climb out instructions from Tower off Runway 33 was heading 210 climb to 4;000 feet.Due to nerves or lack of basic airmanship skills; the PF in the left seat who was being checked blasted through our altitude clearance of 4;000 feet. After multiple call outs from me in the right seat about checking his altitude; I had to physically push the nose down as we climbed through 4;700 feet. At that time we got a TA/RA for a King Air crossing left to right in front of us at 5;000 feet. ATC warned us about the conflict and I responded that we had the traffic in sight. A few seconds later ATC cleared us to a higher altitude once we cleared the conflict.My summary of the events is that due to nerves; lack of basic skills; there is no way to possibly intervene as a PNF when the PF is still way behind the airplane. Things happen at a high rate of speed in a very challenging environment. There needs to be a better way to communicate without having to physically intervene when a conflict arises.
G-150 pilot reported the pilot flying flew through their cleared altitude; triggering an RA NMAC event.
