Pros
If you happen by chance to work with great manager then working can be enjoyable. This might apply base on location, if you work at the branch with slow traffic that will give you a lot down time to catch up on your other works you need to do.
Cons
Customer service from phone support can be frustrating at time, a lot of time instead of helping the clients over the phone, they told the clients that they need to come to the branch to get their issue resolve. They hire you as at-will employment, meaning you can be fire for any reason to no reason at all. Apparently they can get terminate you not because you were doing anything wrong at work but because they didn't like your personal banking habit which they could accused you of violating prohibited conduct. Don't bank where you work, even you are a client with a lot money in the bank, as long as you are their employee, you could get treat as second-class citizen.
