Deloitte Business Analyst interview questions

Received initial interview through a friend and proceeded to have first phone interview with a recruiter. About two weeks later, I spoke with a manager over the phone for 30 minutes and then scheduled my final interview about 3 weeks later. It was roughly 3 hours at the Arlington (Rosslyn), VA location. The people were very professional, quick and down to business. The in person consisted of a final behavioral with a director, and two case studies with two different consultants. I sent thank you letters and about two weeks later, I was asked to submit my initial background check application. I know for a fact that this was not what eliminated me as I've done Federal checks before. About 3 weeks later, I was told that I was not extended an offer. Overall, very quick and efficient recruiting process. My recruiter was there to answer questions throughout.
