Deloitte Manager interview questions

I had 3 interviews within 2 weeks. Wrapped up all 3 interviews under 15 minutes. I think my existing job role was exactly what they were looking for.. It's a matter of being at right place at right time and being honest about what you are working on.

The process consisted of four stages, with two case studies in the middle. All over the interviewers looked quite junior, the case studies were presented on the spot (no shared material, no time to reflect and prepare those) and run in a very unrealistic manner. More than once the interview got cancelled and postponed last minute. Nobody could even tell who the person reporting to was, nor what the OKRs might have been.
