My first interview was on campus and then I was called to set up another interview. Second round, which was the final round, was a half day at the Landsdowne St office with 3 different executives in the company including the CIO (nerve-wracking!). At the end of the half day we were told we would hear back within a week. Since I was offered the position, I heard back quickly from the HR reps but I talked to the other candidates who didn't hear back within the week/at all which seems unprofessional.
