The management (at least in technical specializations) is not prepared to move forward quickly and make full use of the qualifications of the personnel. In many cases they prefer to do things the old way and only adopt new approaches after the need arises from cooperation with the European System of Central Banks (which on the other hand is a good thing because you are sure things WILL move forward after all). Unfortunately they pay little to no attention to the qualification and career development of people. So if you join be prepared to "close" your career paths and just follow the hierarchy development of the Bank for the rest of your life. By the way, this last thing, hierarchical development, is strictly time-based and does not depend on merit or productivity.
