I was being interviewed for a summer internship with this title, they flew me up to Washington for an in-person group interview after a screening interview at my college (which I got through handing a resume to a recruiter through the career fair). This screening interview was fairly simple, one technical question, some questions about what I'd like to work on, etc. Everything is paid for when you're up their, car, hotel, and food. In person interview was a 5 rounds that either lasted throughout the morning or afternoon (there were two groups of interviewees from colleges across the country) and you spend about an hour with each person, and by the end they tell you on the spot if you've passed or failed. Each interview asks some type of technical question where you solve an algorithm, everyone asks for a self evaluation on how you think you're doing at this stage in the interview. Office where I interviewed was fairly interesting, one section had meeting rooms that all referenced video games from Halo to Half Life, there was also one of those Microsoft tablet tables with games on it, as well as an Xbox 360 running Halo. They serve some food, but it's not worth remembering, and there's breaks in-between interviews where they very much discourage you from discussing any of the questions being asked.
