Slight disagreement here. Former bank employee.
Banks hire knowledge workers/creative types/snowflakes.
In fact, they hire the absolute best-credentialed and most-experienced in the market. Our receptionists, mail and facilities staff at minimum had a Masters degree, went to a Tier 1 school and did something very interesting/exceptional with their off-time.
They just try to turn them into drones via compensation schemes and internal politics.
