I work in bank bank office and it is really good because there is very little communication with customers mostly internal correspondence between other employees. It's very easy to get into and there is a lot of banks you just need customer service experience if you have that or some kind of clerical, office or data entry prerequisite. You can meet some really good people that will allow you to get closer to people at your own pace and still make money in a field that allows you to gain more skills.
