There was a case study (i was given a one page scenario), I had to write up some basic advice and then present it to the interviewers (there were two). I then had a series of general competency questions, I was then asked what did I want to know about the firm etc.

1 interviewer asking motivation and competency questions. Very casual. Asked lots of follow up questions and was more like a conversation. There was time at the end to ask questions to them. No prior information about the interviewers before meeting them.
