First round interview was a current consultant calling and asking the typical behavioral interview questions. Then a couple days later, a different consultant called and I did a phone case study. Second round interview was was a group of us all interviewing. The first day was just them taking us out to dinner and giving presentations and answering questions about Deloitte, what they do, and the different service lines. The second day was long - had to do multiple interviews - 3 behavioral/walk through of resume and 1 case study with managers. Then also had to do a group case presentation with an associate in the room watching how you all come up with the answer. Advice: Come prepared with plenty of questions because you meet at least 10 people and they all want to know if you have any questions. It gets tiring. Also, go over the cases on their website.
