Affiliate Marketing Secrets

This is basically regarding a job offer I received from Full Circle http://www.fciweb.net/ sounds like a scam to me, and I believe they are somehow affiliated with Smart Circle. I went to the first interview, no longer than 5 minutes, was called back for a second one, went out into “the field” and saw what I would be doing. I would be selling DirectTV for 100% commission for a good 10-12 hour day. It was somewhat enjoyable considering my interview only lasted an hour and a half, but since I’ve never done sales and I’m right out of college I was skeptical that they would hire me. I was taken back to the office after being told the entire day that they were only looking to fill 3 or 4 spots out of 200 or more applicants and that I should show a lot of enthusiasm towards the position because there were so many applicants and all that jazz. They made it sound like being selected for a second interview was a rather huge deal. I walked into the office, immediately the “manager” shook my hand and said welcome aboard. Sounds like **** to me. I “start” tomorrow, I begin a 10 hour day of walking around Best Buy and trying to get people to sign up for DirectTV, I’ll probably talk to 300 or more people and get less than 4 to actually sign, according to my “trainer”. I was told it was a 4 to 6 month process into management, however with only some college and a degree goal that’s completely irrelevant to Marketing and no experience in sales and they still hired me on the spot practically, I was clearly lied to at some point. Do you know anything about these companies, If this job is bull please share your opinions so I don’t waste my time.
I need advice on how to avoid these scams. I’m barley about to graduate and I’m already being faced with these scams all over the internet, what is real and what isn’t?
Full Circle (I can’t find much on this company at all, its located in Atlanta)
Smart Circle International (Parent company probably)
