Without weight on wheels the ground spoilers won't deploy, as well as not having reverse thrust, wheel brakes or drag from the landing gear. Floating along at high speed in ground effect just above the runway there would have been little cause for the aircraft to slow down until the cowlings scraped the pavement, which was well down the runway. Do we have an indication of the flap setting on the first attempt as 236 kts (at 2000') is over limit for any flap stage ?
215 kts at touchdown is well in excess of the limit just for FLAPS 2 and when configuring in the air FLAPS 1 gives slats only, no trailing edge surfaces extend. With the engines being bumped up to approach idle, the first stage has very little effect on slowing down and is often more use in allowing greater speed brake extension due to a reduction in VLS.
Standard method for configuring an A320 for landing which I would give to a new F/O on the "do this and you won't get into trouble basis", with the appropriate speeds used. Some airlines may require the aircraft to be fully configured earlier, and some pilots might be happy to push it a bit further but this is pretty acceptable for general use.
