The interview process was pretty simple, consisting of a phone screening and then an in-person (or in my case Skype) interview. The HR people that facilitated the interview process were incredibly nice. Me being a junior, they were bluntly honest that the department I was applying for usually goes to recent grads or grad students, but they would work to find me a spot in another department. Lo and behold a couple days after my phone interview they asked if I wanted to be interviewed for a department that was very similar to the one I had applied to. On top of that, I was in Paris at the time my interview was scheduled and they accommodated a time that would work for me to Skype. The interview wasn't too hard, but you should definitely be knowledgeable about the department you are applying to. Overall, I was happy with the interview process!
