When I visited massart one of the grads told me it was $100 for one image and you have to pay the camera operator, so it's kinda insane unless your funded.. Nebraska is cool!
I don't think they tell you till the day of. My good friend had an interview last year and it will a littttttle bit cooky to say the least. they are very theatrical people over there. The interviewee wasn't even from the department she was applying for.
