Pros
High energy environment, proven sales methods, and they shower you with praises. This work will kick your butt into high gear and teach you about hard work. There is opportunity for advancement but its not for everyone, if you have no back up plan and you have some money saved, go work your butt off for them and you have maybe a 5% chance of being one of the few who 'make it'.
Cons
Disgusting turnover rate, you get paid more working at mcdonalds, and the management are cocky/arrogant in a very subtle 'be cool like me' way. The hours are long, the work is very old fashioned 'door to door sales or promotion booths', and no matter what fancy title they want to put on it, its being a salesman, not the good kind but the annoying 'buy what I have before you figure out that you don't really need it' kind. They'll sell you on the idea that you can be rich relatively quick by becoming an owner. but just look around and see how many people come in and how few people stay for even a month.
