Applied online, got invited for an on site interview in NY. There was one initial round and 2 final round interviews with different analysts from the company. Mostly behavioral, asked detailed questions about experiences on resume.

At DB's offices on Wall Street, with a first round interview in the morning and if selected, a second round in the afternoon. Both half hours each. They also told us that evening if we were selected for the internship or not. Interviews seemed to vary widely from brainteasers to fit questions depending on the interviewer. There were 2 interviewers and 1 interviewee in every interview.
