Campus career center online drop box, interviews on campus (really simple case, but don't mess up the numbers!)
Heard that evening that I passed the first rounds, and was asked to take an online verbal/math test. Then was invited for interviews at their plano office. They flew us in, had a reception, and then shuttled from the NYLO to their office the next morning for a tour, 2 case interviews, and 1 behavioral. Do not mess up the math, try your best to understand the interviewers, and don't get flustered.
One negative thing is that the recruiter never answered any of the questions I had. In short, maintaining contact with CO was painful, and the interviewers were not polite.
