YMMV, I find companies in the Midwest would rather you check your empathy at the door.
Maybe it's my Midwestern upbringing, but I'd rather just get my job done than be an emotional sop for my coworkers, or worse have other people be an emotional sop for me.
I don't think you have to be in THAT kind of relationship with coworkers.

And it's in the company's best interest: Turnover is extremely low, which means that knowledge and talent are retained. It makes business sense.
The culture in consulting has its problems, but things are getting better and we’re seeing a lot more women entering senior roles which is starting to fix some of the bad behavior that has traditionally gone on.
As for acting self-important? It takes a fucking ego to have a 27 year old kid tell a 50 year old SVP how to do his job. But as a result, people in consulting generally respect each others large egos, which gets you some degree of professionalism.
