1st interview seemed great, like they were a real marketing firm working with fortune 500 companies. 2nd interview was a real drag. They tell you it's an all-day job shadow, but they don't explain that the job shadow is nothing but going door to door. I asked a lot about the business, and the person I was interviewing with had no idea how it worked beyond the president who worked at Modern Business Concepts. I did some research after the interview and found out that MBC is a branch of a MLM pyramid scheme. I found this article on the consumerist, which not only proves it (8 steps to success, 5 steps to a sale, 4 phases of ownership were a part of the final interview), but also gives plenty of background information to the type of company MBC is.
They will try to win you over with promises of making all kinds of money, but it is all just a way for management to make more money. The more "sales" people they bring in, management gets a higher percentage. They will take whoever they can get as long as they can get them sales. Don't fall into the pyramid scheme.
