I also work for a large IT company and have used the corporate rate for many, many stays. As far as I can tell, no different treatment. But as always, YMMV.
Now I have been able to get a couple of status matches on AA through my company. And AA doesn't normally give out one status match, much less two of them. So company based status matches can happen, I just haven't seen anything from Marriott on this front.
