Pros
I actually liked most of the people I worked with. They were kind and hard working, in spite of constant cut-backs around the office. Benefits package was decent and affordable. There were two options and I had the cheaper one which only cost me about $20 per paycheck. They also offer 401K options that are easy to manage.
Cons
Hard to move around and very few job opportunities outside of the main cities (Houston, Lubbock, or Victoria). Also transferring is not as easy as it should be. In an environment where a teller can be fired for just about anything, it's crazy that some employees were unbearable to work with and never once got in trouble or disciplined. There was a lot of playing favorites, but that's to be expected in most office situations. The company buys out failing banks (which is fine with me) but then to make up for that money until their investments pay off, Prosperity is extremely stingy. Our banking center was actually not provided with facial tissues for a while and we were told we could use toilet paper. This is just unprofessional looking.
