Pros
it's got a good brand name that's recognized on wall street. Lots of interaction with people in the London office since that's their largest operation site. lots of europeans all over the bank. intra sites are functional and communicative. lots of career development classes within the bank to enhance knowledge, but the classes are sometimes not very helpful. the location is very convenient on wall st by subway transit. For IT, there's the internal IT mobility program that's encouraged for you to move from one technology group to another. However you still must be careful. though it is encouraged by upper mgmt, some middle managers are still very petty about letting people leave their team.
Cons
the place is a mess everywhere you go within the bank. I made a lateral move within the bank between 2 IT groups and things in both groups was very disorganized. On a technical level, the bank does not have it's act together in certain IT groups. Also from talking to people in the bank, it seems like it's messy on the business side as well. HR at DB is pure evil. I was sexually harassed by one of my managers and HR, not only did not help me, but also made life absolutely miserable. At the end they denied all that's happened as if I made the entire thing up.
