You are generally flown to a centralized location with other interviewees, and go through an extensive, 3-4 part interview, including a process math problem, as well as case studies. The process itself took about half of the day, starting in the morning and ending around noon. However, there was another group coming in during the afternoon to do the same process. They make the process very easy, asking you the airport you would fly out of, and arranging a flight, rental car, hotel, as well as return trip. Additionally, you are given the ability to turn in receipts for meals, and they did not even require the car to be filled up before returning to the airport.
