I don't think this will really help you with your question, but this is just my opinion...
I had a major in English... does that make me qualified to write a novel? Well, not necessarily...
However, do you want a doctor who has had no formal training, so to speak? Not likely.
What I'm trying to say is that most employers hiring for "professional" positions want an employee who has an applicable degree versus... someone else.
That's not to say that the person with the degree won't have a lot of learning to do about things that they never learned in college, but that's the way it goes!
There are things most people who have earned a degree can bring to the table... that perhaps, but not always, people without a degree can't. But, again, either way a lot of job specific training is likely to be needed.
Some employers, however, do give a lot of weight to experience over recent college graduate. That, however, depends on the employer.
What I've learned about banking has been from the ground up. And banking has a lot to do with numbers and figuring and factoring. Auditing includes all of that... and a lot more. I can't help but think that a degree in either accounting or finance would help, at least initially, to grasp some of the banking concepts which, for me, in the beginning were pretty overwhelming.
Whew... that was long-winded! It will be interesting to see if anyone with those kind of degrees have a different perspective!
