I figured i'd put in my experience.
I was in college and desperate for a job, so i was applying pretty much everywhere. I got a call back for a "sales representative" job and i was incredibly excited. The job was listed in a very deceptive manner, leading anyone reading it to think they have "pre-set" appointments for you to attend and sale a product.
The interview is the same story as most (run-down building, lack of decor, etc.) but the younger man interviewing me went on about how they were looking for "professionalism" and etc. It was emphasized to me that this wasn't a door to door sales gig, but the appointments were all "pre-set". I explained that i was willing, but i had a week (three weeks after the interview) that i would not be able to work or be contacted. Got a big "not a problem!". I was then offered the "second interview", which turned out to be him running through the manual they use to sell knives. After this i was promptly offered the job, and very excited i agreed (despite the training being unpaid).
The training was learning to go through the manuals and cut pennies, etc. The knives were high quality but the training was literally just reading the manual. It wasn't until the second day that we were informed we would be setting our own appointments, with family and friends! I agreed to continue because i had already spent so much time there i figured, why not give it a shot? Things went downhill. I was asked to provide names for people who might be interested (long before i had ever experienced what the job was like). I was uncomfortable doing so, so i declined. I was then promptly pressured into it by the manager. I only gave over names after being assured, they would be called once and if they were interested that was it.
The job experience was completely different then i was lead to believe.
