I got an interview at DB because the IT director of the company I was working at sent my resume to the IT Director there . I first interviewed with the Director and he went through my resume from beginning to end. Since I didn't come from an IT back ground, he quizzed me on the risk system that I was using in my current position to gauge how much I knew. DB was using the same risk system that I was currently using so he wanted to see if I was willing to be more of a support person instead of an end user. The questions were not too technical. He was more interested to see if I was willing to learn other commodities and how much of the system I knew.
Next interview was with the project manager. His questions were very general and wanted to know why I wanted to take on more of a support than a front office role. We went through my resume to gauge how much of the system I knew. The interview took 1 hour.
After the interview with the manager, I interviewed with two business analysts at the same time. I knew one of the guy who interviewed me because he used to work at the company I currently worked at. Out of all of the interviews, this one was the most relaxed. We just talked about what my hobbies were and what I liked to do. They were more interested in how I would fit with the team.
After I interviewed with the two business analyst, I interviewed with three more front office people (gas trader, gas scheduler, and mid office manager) and one back office manager (accounting).
One recurring theme that I noticed with all the interviews is that I either worked with everyone who interviewed me directly or indirectly, OR I knew someone that they knew.
