Giving suggestions on a finished product seems a bit useless, but bear with me since I'm only doing so to flex my creative muscle some....
I liked it, but it felt a little flat to me.
I think starting his emotional fall outside would have yielded more contrast and helped forge the idea he was entering (literally) the world of the corporate process. Maybe begin with his girlfriend walking away crying, leaving him alone on the sidewalk. No dialogue would be needed, just his exposition. Plus, the sets were so similar in theme that I didn't get much sense of any time lapsing or a change in environment.
Outside of that the cinematography was really nice and though I couldn't understand the language (German right?), the acting seemed believable.
Overall a very well done film.
