Many Bank positions are just cogs in a wheel. Just about anyone who can read, write and do a little math will fit in fine.
The more losers they hire the more capable people they’ll need to do the work for the incompetents. The federal government does this all the time (i.e., hire skilled contractors to do the work the employees cannot or will not do). In other words the government pays two people to do what one person should be doing.
It goes on all the time. I kid you not.
