Deutsche Bank interview questions

Interviewers ran over an hour late for previous interviews, so I sat in the waiting area for a while. On campus interview, consisted of a first interview with 2 younger associates. Mostly "fit" questions, asked about stocks I was following. Very pleasant and personable, I felt this part went very well. Then passed on to a hiring manager or something along those lines. Asked what were meant to be "brain teaser" questions, but seemed to be a bit inappropriate in level of difficulty, given that it is an undergraduate internship position. Fairly rude and this part only lasted about 10 minutes.
