I applied through an employee referral. The process took 2+ months. I interviewed at Deloitte (New York, NY) in Nov 2011
Interview
Met an alumni who was a manager in ERS at an accounting fair, gave him my resume and got a call from a recruiter days later. I had a phone interview for my first round since I couldn't make it to the office on the date of my first interview. After that I received an email inviting me to second round interviews and a special "Inside Deloitte" event. They paid to fly students in and put everyone up in a hotel (except I was already in NYC so it didn't matter). The night before interviews was a dinner attended by partners and other employees, they gave an awesome presentation and an office tour. Everyone was very friendly, they just wanted to make sure you were a good fir for the company.
Interview process was smooth but took time to be scheduled. After the interview, feedback was quick but the interview was rescheduled several times. Interview consisted of behavioral questions with 2 interviewers from the same department.
Interview questions [1]
Question 1
Tell me about yourself. Why this role? Why this firm?
Two step:
one online video assessment with three questions
one live interview with 2 members of the team with ~10 questions
The interview was laid back with mostly behavioural questions asking about my past experience and how I could contribute to the team etc.

Walk us through your resume.
What about this team interests you?
Straightforward friendly interviews. Recruiters are helpful and staff are welcoming. The process involved two interviews with a Manager and an MD. They came back with a decision relatively quickly compared to other firms.
