Ok progress. The first round interview involved two interviews. One was a run-through of my CV while the other was a case study interview which involved two business propositions and you had to determine which was more beneficial. The next round involved two more case interviews. Some of the interviewers were nice, while others appeared to be distracted during the process.

30 min "tell me about yourself", and 30 minute case study. They were polite and professional but it seemed like a lot more pressure than necessary. The case study portion: the interviewer had a sheet with solutions and what they were looking for in front of them, but it didn't seem like they were super accepting of differing approaches to the problem.
