I know this is extremely late but I'll answer this question for anyone else who may be thinking the same thing.
The simple answer is no. When you are interviewed the person isn't just looking at you for the position you applied. They look for any place they can fit you, where you would excel. When I did my interview I applied for the games department.
Yes, the department was hiring but the manager noticed I had a lot of experience with computers and they needed more people in that department so they hired me for computers instead of games.
So in conclusion, when you are interviewed they look for more than just one department and if the interviewer didn't like you, its most likely that they won't find you a job in another department.
