Unfortunately I know a little bit about this because I did it for a few months 20 years ago.
It works the same as MLMs. They use cult like behaviour to exploit young adults.
At the top of the food chain, is Appco, used to be called Cobra Corp. Its an American company.
The premise is that you go door to door getting people to sign up for charity, or change gas/elec suppliers etc. You only earn money on the commissions.
But, the real deal is they want you to build your own team and open your own "business ". You earn more money from people who join your team. - is this sounding familiar?
The truth is its a terrible business. There is lots of lying, bullying, and horrible tactics being used to exploit mainly people in their twenties.
It's starts with a job advert that's a massive lie. Something along the lines of "do you want to work in Marketing?" Etc.
You turn up for an "interview".
You spend the day following someone knocking on door to door. But this is when the cult tactics start.
Your told over and over again that people who work 9-5 are idiots who will never be rich, but in this job, provided you do everything they say, you will be a millionaire and retire by 30.
You have an interview with the Owner and made to feel you have to do really well to get the job, but the truth is you got the job the moment you turned up.
There is lots I can tell you, but my post is really long already 
I try to help the people who knock on my door to understand what is happening.
It's really difficult because they make you work from 9am to,often, 11pm. They pretty much cut you off from family/friends because they will "neg" you. So it's hard for them to hear from a stranger that what you are doing is a massive con.
