Ventajas
The Bank has realized faster than others it needed to refocus on its core activities and locations. Now that the cuts and refocus have been done, the Bank is back on trying to develop its core activities. Given the high turnover (see below) among young/bright people, there is room to learn and impress, and you can gain responsibilities fast up to Director level. There is a good work/life balance, and you rarely come across really nasty colleagues
Desventajas
The bank is bureaucratic, risk adverse and slow to change. Overall salaries are lower than industry standard. There is large turnover with bright people systematically leaving the bank after a few years to get better salary elsewhere. After reaching a senior position, politics will be the only driver of career advancement.
