Great starter job, do not be naive.
Pros
They will sponsor you for licensing i.e. (Series 7, 66, insurance licenses). They will reimburse you for licensing costs. That is all you will get. You will be part of a team, and you will be supported by and support that team. You can opt for a salary option, but that will reduce your commission rate. You will work long hours and your compensation will be abysmal on an hourly basis, even if you make six figures.
Cons
You will not be given serious training. You will not learn any insights about financial planning, investments, or even insurance unless you try to learn on your own. The turnover rate is unbelievable. Turnover of associates, managers, entire teams is abysmal. The prospecting schemes are at times unsavory and at times cringeworthy. If you are part of a team you will have to do what that team does without fail. The knowledge you gained by studying for and passing the series exams is vastly superior to the "training" you will be given.
