How much are you making a year now? How much is the bank offering you in terms of total annual package?

Very hard to advise if the most important information is missing.

In general bacnassurance specialist are hardcore sales job in banking. A minority can sometimes forge a new career in the proper banking sector, but my advice is do not join the bank with the expectation that they will be able to offer you a structure promotion into higher management. If it happens its a bonus.
