Lots of problem solving form questions for the application to the interview. The case studies during the interview process was intense and you definitely had to be on your toes.

I interviewed at the corporate office in Richmond Virginia. First was an online numerical skills test and personality test. Then had a phone case interview. I then went in for a full day (6-7 hour) interview process at their corporate campus. I was told essentially nothing except to show up at the specified time. I went through 4 separate interviews with various employees, 2 of which were further case interviews. At the end of the day I took an oral drug test and answered a series of increasingly bizarre questions about my past ("Since age 18, have you ever committed homicide or rape?" Seriously? This is an interview for a professional position.) I wasn't offered the job and wasn't provided any reasoning why beyond a generic rejection. I found this somewhat disrespectful after such a lengthy process and time investment on my part.
