Pros
Great first step and a career notch on your CV. You won't be changing the world here or even remotely close but it gives you a good sense of confidence and a good sense of work place practices if you are fresh out of college. Great work life balance though, very family oriented however and there is a clear preference in terms of flexibility for people with families which is a little unfair but at least it is there. A nice place to retire in. You can get lucky with teams also as some teams are great, some teams are hell. Expect late nights and weekends now and then due to incredibly inefficient release processes in some cases. Plenty of encouragement for career advancement but then when you tick all the boxes, it's not enough so be prepared to walk if you want to move up. It's a giant corporation and has all of the attributes of one so a little push pull is needed to get to where you want to be. Great community spirit. The Bank does a lot for the local community and really is heavily involved with philanthropic efforts. Even if it is just for PR it does benefit the country.
Cons
Hard work and exceptional talent doesn't really count as much as it should. Spend time and money rejuvenating old redundant processes and let developers focus on development not bureaucracy. As a company, the bank tries desperately to think and move like a tech company but ultimately stiffened regulations and fear of change from senior managements brings good development and projects to a halt. Additionally there is just an awful amount of mediocre developers just doing enough to survive and this leads to a lot of frustration and costly meetings where good developers are driven to agree to the majority rule. No realization for the power of open source technology. Time is seen as the only real measure of experience not performance.
