Three interviews in total, first one with the future line manager and another senior member of the department. It was a get-to-know-each-other type with no difficult questions asked. The second one was with two members of the team you would be joining. Also, fairly standard if not a bit more technical and checking on how much I knew about the rating criteria. The final one was a case study that was emailed to me and had 3 days to send the presentation back to them. I had 20min to present the case study in the final round and was asked technical questions afterwards. The case study mimicked the actual rating process and basically involved applying the relevant criteria to come up with a rating recommendation. In the final round there was the department head, the future line manager and another senior person.
