It started out with a phone interview. They wanted to verify a few things on my resume and talk about my interests. They then proceeded to the 1:1/Group interviews. The trip was all expenses paid, which was pretty cool considering it was only my second real interview. The interview process took about three hours where I spoke with five different departments. I was a bit nervous when told I would be having four to five interviews in one sitting; however, everyone was approachable and knowledgeable. They simply ask you questions about your interests and experience. You are trained after being hired, so it seems to be kind of a personality interview combined with what you know.
