Every franchisee decides to run their stores there way - so even if you go to the school you might be absolutely screwed when you get into a store.
Pay scale is rather awful if you're looking to make a living - it's really based on your sales - and due to the brand recognition you will literally be fighting people to buy product and give you that 3% commission.
Benefits are at the discretion of the franchisee (I had none).
Work/life balance is pretty awful - you'll be expected to work shifts like 11:30-9:30 regularly, and expected to cover sick calls, stay late, etc.
Actually working on the floor can be rather awful as well - you make your business, and you can be one of the company's top sales people and still be standing around for 4-6 hours a shift - soliciting in the mall hallways (the worst part).
Product discount is OK, franchisees will still try to make a profit off of you so expect to get a very basic discount on skin care/cosmetics (that aren't even amazing).
Upper management is *kind of* helpful - but if you ever experience issues at work (mistreatment, improper conduct, shorted pay/hours, tips go missing etc.) they'll always take the franchisees side (remember, franchisees are THEIR customers so they don't care about you).
Long hours, no brand name recognition, poor pay scale, poor working conditions, inconsistent upper management
