Deloitte Interview Process - Round 2: What to Expect?

I'd like a bit of clarification on the Deloitte interview process I'm currently involved in.  I'm an experianced consultant with many years spent at IBM where I managed a portfolio of enterprise customers.  My Deloitte interview experience doesn't seem in alignment with what others have shared as a general process on preplounge.  My first call was the recruiter screen ('fit test'?).  My second interview call is one day away, with a Partner focused on PLM.  As far as I know, interview 2 is simply another call, no mention of a case interview as others have stated was their experiance.  If given the green light, I'm expected in Chicago next week for the actual 'live' case interview.  I asked the recruiter to share the structure of that 3rd meeting, but did not hear back.  Entering a discussion without knowing what to expect makes it hard to prepare.  Anyone else experiance similar?
