Deloitte Senior Manager interview questions

It appeared that their mind was made up even before the interview had started(maybe because I had a qualification from another accounting body and not ACA?) They didn't really ask me any questions, they just told me about the role. I heard a few days later and the feedback was that they came across other candidates that were "stronger" than me

There were three rounds of the interview: HR manager, Hiring Manager and Future Supervisor. Also, there were reference check and security check. It seems that all three interviews were up to the point.
