I really don't think time in this particular type is a factor. None of what I've heard or read has anything to do with familiarity with its unique systems. Everything sounds like sloppy flying. Sounds like he, the PF/PIC/Captain, started the descent late, stayed too high, didn't manage the power curve well, landed long and fast and willfully ignored his first officer. One bad decision after another where instead of properly correcting it or making the safe decision to try again he decided to plow onwards.
The training pilots go through to get type rated and to be allowed to fly by airlines is incredible. But knowledge is one thing, attitudes and behavior and truly taking safety to heart outside the sim is another. I bet this guy was slightly reckless in every model he's flown.
Another alternative is external social factors acting on the captain. Maybe he was distracted by personal issues. There again though, if you're not fit to fly that day, you call out.
Yeah, time in this type could be argued as a reason they weren’t properly configured or on a stable approach, but that is exactly why go-arounds exist. Mistakes happen, errors get made, so you go TOGA, fly a holding pattern until you get sorted, then try again. Happens at every airport every single day. No harm no foul.
That is not the reason this incident happened. This happened because the pilots continued to put it on the ground while ignoring at least a dozen clear and unambiguous indicators to abort the approach and go around.
