Been there done that, training some of our 200 hour total time second officers, i.e. our SO's operate as a pilot in the right seat doing take offs & landings unlike most other airlines where they occupy the seat in cruise drink coffee & eat crew meals while doing R/T & the flight log, with these inexperienced pilots they tend to have problems below 200ft in maintaing the aim point or they become fixated on it & have no appreciation of the ground rush & either forget to flare which requires an immediate take over to prevent a hard landing & potential bounce or in my cases they over flare & balloon with the thrust levers at idle, so now you're below Vapp with idle power back at 20ft, you don't have much time but you have to select TOGA (fire wall the thrust levers) maintain pitch attitude don't change config & wait to spool up & accelerate to fly away safely then clean up, on a few occasions we actually bounced on the runway as engines spooled up, whist you are on the ground the config warning also starts blearing away because the computer thinks you are taking off & you are not allowed to do that in config full, so as you can see its a very dynamic & at times confusing maneuver for a line crew, definitely more complicated than a norm go around.
