Partly - they seem to have pooled information and communicated well. The FO(s) seem(s) to have deferred to the Captain appropriately.
I beg to differ here; although they did talk a lot, it appears that important "standard" pieces of information were omitted (see avherald excerpt below). Agree that it was not a CRM breakdown that caused or significantly contributed to the crash though.
At 02:10:47Z the thrust levers were moved to about 2/3 of travel resulting in 85% N1. The climb rate reduced to 100 feet/min, the angle of attack reduced to about 3 degrees and the roll is controlled. The first officers now attempt to call the captain back to the cockpit. The BEA analyses that after a quick trim and levelling off as result of PF inputs the trajectory of the aircraft appeared controlled again, however the initial increase in altitude was excessive and should have been pointed out by the PNF. However, none of the pilots called out speeds, vertical speeds, pitch angles or altitude.
At 02:11:37Z the PNF pushes the priority button and provides a large left input in reaction to a high right bank, calling "controls on the left". He almost instantly released the priority button and ceased control inputs again without required calls.
At 02:11:42Z the captain entered the cockpit, just before the stall warning stops, the airplane was at 35800 feet MSL, 9100 feet/min sink rate, airspeeds below 100 KIAS, pitch 12 degrees nose up and engines at 102% N1. Neither first officer provides an account to the captain what is happening.
