Just wrapped up an offer from Deloitte Strategy & Operations and want to put real notes here while it's fresh.
Rounds: recruiter screen, then a virtual "fit" interview, then two case rounds back-to-back (they call them "case interviews" but one was more of a business judgment call than a structured case), then a final partner call which was almost entirely behavioral.
The case format: more collaborative than McKinsey. They pushed back on my framework a couple of times but it felt like genuine dialogue, not a stress test. One case was a cost reduction scenario for a retail client. The other was market sizing plus a brief recommendation. They wanted me to structure quickly but were fine if I didn't follow a rigid framework as long as my logic was clear.
What actually mattered in the behavioral rounds: they kept coming back to "client ownership" and moments where I had to deliver difficult news. I had a story from a consulting project where we found the client's own team had caused the problem and I had to present that diplomatically. That story came up in two separate rounds.
The partner call: mostly conversational. She asked me what I thought Deloitte's differentiation was versus the other MBB-adjacent firms and whether I had any genuine interest in a specific industry vertical. Felt like a culture check more than anything.
Timeline was about 5 weeks from first recruiter contact to offer. Reasonable by consulting standards.
