The know-it-all coworker has an opinion on everything and corrects you without being asked. It's exhausting because you're never right.

The colleague who derails a 30-minute sprint review by saying 'well, technically...' to quibble over an irrelevant semantic point purely to establish intellectual dominance.

What grinds my gears is when they give patronizing advice on code or documents outside their own department, then refuse to admit error even when proven wrong in the docs.
