The process took 2 weeks. I interviewed at Deloitte (Sydney) in Apr 2012
Interview
Online application, phone interview, personality and intelligence test, assessment centre then partner interview.
Overall the process was relatively stress free. Most people are very friendly from Deloitte unlike other interviews I've been through. Except an HR scold me for leaving her a voice message which is 'too long', which made me hesitate on accepting their offer. However in the end I did accept the offer as I decided that Deloitte has a culture which suits me.
