There were different people in different rooms. My group of interviewees would all start in a room. Get asked a question by the person in the room and get about 5 mins each to answer the question and also to ask the person any questions if we had time. We would then rotate to the next room with a different person and different person.

Applied for position through temporary agency. Must pass basic Windows and Accounting test, before being selected for in person interview. Not sure if temporary agency or Company itself made interview and hiring process stressful.
