Deutsche Bank Structuring interview questions

Recruiter, 4 rounds of interviews, a lot of technical questions, some people were quite aggressive and unpleasant. The entire process took a very long time. I was asked motivational questions - where do you see yourself in 5yrs time - why do you want to change jibs technical questions - construct a portfolio that is long vega and flat gamma - how many basketballs are there in USA - what is price of one touch if you know the price of digital

4 interviews back to back (overall >2.5 h) with people from the department, all senior bankers, first introductions, then some technical questions on options theory, BS assumptions, etc.. the usual stuff
