Deutsche Bank interview questions

First it was a numeric test. They asked me to finish within 7 days. The test is very similar to the Citi One. The first tel interview is consists of some general questions. Which can be found at wiki job. I thing my answer about investment banking is not clear enough, so I got rejected after the phone interview.

Resume was submitted by a recruiter and they ask to interview me in person, with no phone interview. Hiring manager was a bit late, finally went to a conference room and started interview, which was mostly technical. Manager seemed tired and angry because of some other reason than myself. He was a very tough interviewer. Questions were mostly about design, C++ and multi-threading.
