Avantages
Excellent training program (although I have heard they cut back on this recently) A higher range competitive wage & benefits with regards to CSRs/Tellers in the banking industry. A young, enjoyable team to work with (depends on area, but usually the workbase when I was there was young, and the culture evolved from there). Gives great experience with regards to problem resolution situations and general interaction professionally with the public, generally good support and development from your managers (although YMMV once again).
Inconvénients
Little room to move up; it was difficult to apply for better positions as the competition was fierce, and people didn't tend to leave (Account Managers). Wage growth potential wasn't great. Seen cuts to benefits programs.
