If you wana cheong sales and intend to make serious big money, you should be targeting enterprise level sales in other industries or PB/IB in banks. Why waste time on mass market retail sales jobs?
Even if you want to do mass market sales, property / insurance agent is where the big money is, not working in some low level sales job in banks. Hardly any top mass market banker make >700k annual compare to top agents in insurance / property where >1mil is common
