Looks like bad numbers, normal rotation then it just stuck until it accelerated more.
Bad technique won't keep the plane from flying at takeoff pitch, even if you over-rotate.
Guess somebody might have mistakenly rotated at V1 instead of Vr, but that seems far-fetched. Basic monkey skill, even the worst possible 200 hour Euro pilot should have that well in hand.

Even if someone rotated early, there are pitch limits for a reason. It looks like someone tried to pitch to the flight director and just kept pulling until it came off the ground. Or maybe they just needed to grind enough weight off the bottom to get airborne. or were a lot heavier than they thought. Or it was job security for their cousin who runs a repair station. Or someone said, "let's make a really expensive, cool tik tok video."

It's not clear to me from the video whether they could have held a lower pitch and got it airborne in a reasonable time frame. Looks like not, it barely got off dragging the tail.
Might also have been a bad trim setting, but it didn't look like an excessive rotation speed (my eye isn't calibrated to widebodies though). Maybe it rotated itself early and the pilot just didn't prevent it.

Juan has a perspective, and I think he does fly the plane...

Yes, I would have stopped at the pitch limit... for a few seconds. But you're way past V1, don't have time to send for new numbers, so eventually you're going to pull for the moon cuz you need to get it in the air. I'm not going off the end holding the pitch limit just to save the tail skid.

If the thing won’t go you need more blow.
At some point you may need to consider just pushing the thrust levers to the stops.

that would have generated a config flaps takeoff warning, never would have gotten to rotation unless they choose to ignore a loud horn, red lights and other messages
