Mostly relaxed, the interviewer was not from the HR department but an analyst who had worked there for 2 years already. Absolutely no prior knowledge was assumed, it was mostly going over your CV and then personality questions to see how you would react to different type of situations.

2 interviews in a row: fairly straight forward. There wasn't any technical questions as expected (internship for first year bachelor students). It was mostly motivation questions, what attracts you to banking, what interests you in financial market etc... Thew logic/reasoning questions, no right or wrong answer, you just have to elaborate a bit on problem given and give your point of vue.
