The interview process is unparalleled by any other firm - 5 or 6 phone interviews, a skype with the CEO, a 6 hour in-person interviewing day consisting of 3 or 4 in-person interviews and the case study. And, another full day of personality and IQ tests. What does it result in? Awesome, competent people to work with. Best out of any firm I've ever seen or heard of. The people here often come without the egos as well - which is great.
