Deloitte Risk Advisory Graduate interview questions

Online application process, game-based assessment, first round interview with case study involved and final round interview with presentation involved. First round interview went well, interviewer was engaged while case study was not too bad. Waited three weeks to be told of the outcome although I was told it would take maximum 3 days. Finally, my final interview was scheduled 4 months later, 4 months! Was given a call on a Friday to schedule my final interview for the following Monday, so only had 3 days to prepare. Very considerate of them. Final interview went okay, but midway through the interview I can see my interviewer zoning off with his eyes about to shut (not kidding) when I was answering his questions. Doesn't show much professionalism for a firm that advocates it a lot. Overall experience was okay, but a little glad that I didn't get the job in the end after having gone through the entire application process and experiencing the interview treatment.
