Pros
Health benefits are great. Most people are friendly. There is a lot to learn if you are willing to put in the time and effort. And for those who prove themselves are always rewarded with more work. (Not sure if you can categorize that as a pro?)
Cons
Most groups are under staffed and over worked. If you have read other "Glassdoor" reviews of Mizuho Securities you will know there are many issues with the IT Department. It seems harder and harder to find the best and brightest employees to join us. Mizuho seem to be hiring those that are good enough while those that are still here are jumping ship at their first opportunity, and who can blame them. You have to feel sorry for those that are left trying to get the work done in this very unhealthy environment, no matter how much they get paid.
