I'm not sure what your final interview will be like, but as for the psychometric testing, its the standard MMPI (Minnesota Multiphasic Personality Inventory) which has about 800 questions. Well, kind of, its more like 150 questions reworded 5 ways. Anyways, you can't cheat it and it does give a remarkably accurate idea of what your personality is. After this, you will see a psychologist to talk about your results and insure that you told the truth. To my knowledge, this is the same test they give to everyone at EK regardless of department. In fact, if you switch jobs within your department, you will do it again. Go figure. As with nearly all interviews with EK, be yourself, and you will be fine. Wish I had more information for you, but don't know much about that departments interview process.
