Group case interview with 7 other candidates, brain treasers etc. Very basic stuff, where the interviewers (three of them) were looking for candidates that could handle group dynamics and was able to adapt to the rest of the group.
Then some group discussions regarding ethics, where they basically laid out different scenarios one might find one self in as an employer, and they want to know how you would deal with those situations (insider information etc)
Next round was one-on-one interviews with managers and seniors, mostly regarding CV and learning about one another
