I was interviewed for about 4 hours. They brought us all in as a group and gave us an Interview Schedule. I was interviewed by five members of the LT and BUL Group. So, essentially five independent interviews. The questions were the exact same in every interview. I was then interviewed by the DM by phone after it was announced that I was head to head with another candidate.
I was given the offer and asked for 3 days to think about the acceptance, which they were very hesitant to allow.
