I had this interview in 2012. It was a very technical interview. Consisted of two parts: theoretical and LAB. Level of questions is ccnp/ccie. The laboratory equipment was Juniper SRX and Force10 switches, but it was emphasized that there was no need to know the interface, because they allowed you to use the Internet and if something was not clear, then you could ask questions. Laboratory work lasted for 4 hours. Non standart task.
