I interned at a bank, and let me tell you, what the employees told me - They really hate the job, promotion is unthinkable despite what many from the outside think, one of the guys I was assigned to, had to work for 5 years as a teller before getting promoted, and many of his colleagues are still at their previous position, and the lucky ones just shifted upwards only one step. Few success stories might paint how you view banks, which is as this goldmine of prosperity and constant growth, but the reality is, this stories only apply to those few, not to anyone or the majority.
