Typical unhelpful answer: it depends on the company. I worked at a place with 100k+ employees but where everything was strongly team based, with distributed authority, and it would have been very weird to have a new centrally hired person forced on a team. Otoh I suspect there are much more homogeneous or process driven places where it's cool for someone to just show up and say "I'm the new X" and start doing their job. Like in the military as an extreme example. Really depends.
