Not finished concrete at all, this floor is completely unfinished for a what looks to be a residential space.
You would have a polish, sheen, etc. to the concrete, this just looks like what normal subfloor would look like before you put down tile, hardwood, carpet, etc.
My basement floor looked exactly like this after we pulled up the carpet before we put down hardwood.
