I applied through university. The process took 2 months. I interviewed at GEICO (Washington, DC) in Dec 2013
Interview
Short essay, then phone interview, then in-person. Overall, it was a very long and drawn out process. Of all the places I have interviewed, this took the longest from start to finish. The in-person interview was fairly standard. Several rounds, each focusing on different aspects. One unique part of the interview is that they sit you in front of an excel spreadsheet and give you a case.
