Sure, she is posing in the pic above, but that is nothing unusual for an interview photo session.
Here is another photo of her, taken a while back; apparently in her office (and again, posing):
If that is indeed her office, then the whole "geek dorm room setup" is probably the real thing. Just because she looks dressy and completely out of place with the surroundings in those photo shoots, that does not mean she rocks up to work every day like that. And even if she does, why should her image be incompatible with the environment portrayed?
I personally have several female friends who dress smart, conservatively, have professional jobs, earn more than I ever could, and yet their place is filled with all sort of toy junk...
including beige PC cases with its guts littered on the floor.
