Certainly on the later generation Airbus FBW aircraft, there is a bounced landing mode, where the aircraft deploys the spoilers after the second bounce. This is to positively make sure that the aircraft lands, although the outcome can be a severe hard landing - the lift is effectively destroyed.
I investigated a severe hard landing where the pilot had been completely taken aback by this function -the aircraft dropped like a stone from about 10 feet. The aircraft behaved as per design, but it took the PF completely by surprise.

It is possible that there was severe vibration from the NLG during rotation as the nosewheels left the ground (I am aware of this happening, and being particularly startling as the NLG attachments are effectively under the cockpit floor). That could possibly have given a 'surprise' to the crew at a critical point.
