financial advisor, business analyst, financial analyst in my opinion are better approaches than a teller. once you have your degree you can advance in pay as an analyst, advisor, or become an accountant. anyone can be a teller..
but anyone can be a financial advisor too. its an all sales job with a high attrition rate.
i would start thinking what field you want your career to be in. there's a lot of exciting things to do in business beyond banking. social enterprise, to me, is an exciting and growing field. credit unions can be an option. even nonprofits. I work for a nonprofit and usually when I tell people that they automatically think "social services"..helping people on welfare, or connecting people to jobs or some sh*t. But we're a CDFI (community development financial institution). We do business lending and even have financial products for consumers that beat any consumer savings account by any mainstream bank. We do financial coaching and consulting for small businesses. I got into the field through a recommendation by someone at Morgan Stanley. It's given me great work experience. It's easy work. The pay is more then you would think. I'm not micro-managed. Don't have any quotas. I'm currently getting recruited for an MBA program that's offering me a scholarship that will allow me to pay 11% of the tuition.
The point is...I think you can get lost in the big companies. The reason I was able to get the experience I have and do the things I've done is because I'm at a small company. I was basically given the freedom to do with the position what I wanted. I thought about going into banking because, through my job, a lot of my connections are with bankers, people in government or at FDIC and Federal Reserve.
You want to be in a position where you can network. Being qualified is only half the story. People just gotta plain like you for you to get the job and get to where you want to be.
