Broad questions with an expectation of very specific answers on financial instruments, corporate business products, difference between a bond and equity, "window" SQL, aggregating data and data analytics, data lakes and warehouse etc. Not something people without extensive experience can answer and even when I said I am not familiar with something, I was asked a follow up question in the same area. Whilst questions were quite technical, at the same time there is no clear idea of the role and what project would the person be working on which is not ideal. The interviewer was unpleasant and felt more like he was trying to prove more what you don't know than ask questions, he'd also educate on answers you didn't know which normally would be nice but the way he communicated was strange and seemed more like he wanted to stroke his own ego.
