There were two phone screens. The 1st was the toughest. They notified me of an in-person interview a month later and then cancelled that interview the morning it was supposed to happen which was unsettling and cost me a day of leave at my then current job. The following week I attended the rescheduled interview. It took nearly 6 hours. I spoke to 6 people for nearly an hour each. Most of these people were not the names provided to me in the itinerary. At one point they forgot about me and left me sitting in a meeting room in which a meeting started taking place. That was embarrassing for me. It was an unbelievably long and grueling interview process. I recommend others to make sure they eat and make use of the bathroom before going into it.
