The interview process is exactly like what they tell you in the Information Sessions the Dept. of State conducts each month. If you get waitlisted for an interview or schedule an interview, you should get invited to this and attend. The process took me 6 hours, and although they say you can bring food, they don't tell you when you are allowed to eat the food, so take initiative and eat when you have a few minutes between the different parts of the interview. Otherwise, you might starve and do poorly on the interview.
