I applied through college or university. The process took 2 days. I interviewed at Deloitte
Interview
The interview process consisted of three total interviews on campus. Once selected for an interview, the process will be two days. The first day is one 30 minute case interview followed by a 30 minute behavioral interview. If you are successful at these, you will be called back to attend the 2nd day. This is one more case interview. Once the interview process is over, they were very quick to get back with an offer (about a week or 2).
Interview questions [1]
Question 1
The case interview can be tricky if not prepared. The cases are real business scenarios that generally reflect a current project at the firm. The interviewer is looking to recognize logical thinking capability, even if the answer given isn't necessarily "right". There are multiple possible answers so it's the approach that matters.
I applied through a staffing agency. The process took 4 weeks. I interviewed at Deloitte in Oct 2012
Interview
Two rounds of tecnical interviews one interview with Sr Manager and final communication round. Interviewers were very friendly and questions were very conceptual. Questions related to the work done in past projects are very important.
The final communication (versant) round was very challenging and I saw so many people getting filtered out who were confident after technical rounds.

Why do you want to join Deloitte when your current company is equally good?
