First, there is a resume and cover letter drop by the recruiting deadline in early fall. Then, first of two interview rounds started three weeks later. We were notified a week and a half before the first interview date although they were flexible on the interview week in case there was any date conflict. Those outside the immediate office area did first rounds over the phone. First round is basically all case driven. Doing well on both case interviews while being able to answer a few personal fit questions meant that you passed the first round.
