Everything else.
They will not pay you a dime until you are fully licensed. When they finally do pay you, the base is $2,000 a MONTH gross (before taxes). That's a $700 paycheck every two weeks. When making this offer, they will present you 2-3 different pay structures. One of them is full 1099 (contractor), you will not make a dime, but will keep a high commission percentage.
"Building your book of business" is a lot of reaching out to grandma and grandpa to see if they'd be interested in signing on for life insurance and framing it as, "financial advising." Embarrassing. Other companies offer vastly greater support and better benefits, you can and should do better.
Given that the company is located in LA, where the median rent for a 1-bedroom is $2,661, it is completely absurd and exploitative to offer employees a base pay of $2,000 a month before taxes and zero financial support during the 2-3 months they are studying for their exams.
Your hiring manager will pump you up, and they will make promises, as every company does, but don't be fooled. If you can find another opportunity: PLEASE do yourself a favor and find it.
I accepted this job offer when I was 21, fresh out of college and was naive.
You are at your most vulnerable then. As a 25 year old, I wouldn't recommend this career path, and this heinous pay to anyone. Do yourself a favor and negotiate your base, or better yet: find a company that will pay you a livable wage and won't push you to go full 1099.
