Pros
Wells Fargo is a good place to learn about the complexities of managing a large, sales-oriented business. It is very customer focused relative to other financial services companies of its size, and values thinking and doing across particular product lines to find better ways of creating and benefitting from value for customers. It is also not particularly difficult to manage time for the rest of your life there. There will be periods when you have to put in some longer hours, but compared to elite companies in other industries like technology, consulting, investment banking, or retail, you generally have rather light hours. You mostly get ahead by working smarter rather than harder than other people.
Kontras
Your colleagues will generally be B players rather than superstars. I suspect they are better than the average worker, but still quite a ways from the very best and brightest in the world. While that means if you are an A player it's easy to outshine the majority of folks, it will not necessarily be easy to move around in new positions if you are really good at the one you have, as people will come to depend on you very heavily in your own department, and others may be intimidated by you. It's a pretty political environment. If you're not good at this, you'll get rolled over. If you are good at, you'll have no problem getting things done and getting ahead.
