I actually went to the "Second Interview". This involved meeting a trainer who had been doing the "marketing" for a couple of months. We were briefed by one of the managers and then given a map and some forms. My trainer said that we were the lucky ones since we didn't have to carry bags (more like large suitcases) around like some of the other marketers. When I asked him if they marketed the items to Companies, he said "No, just in pubs and stuff". I saw some of the items they sold and they were the sort of things you see being hawked on the street i.e. stuffed animals, useless kitchen tools etc. I should have just left right there and then but decided to follow my trainer.
We took the tube (had to pay out of my own pocket for a day pass for all zones) to some suburb of London (this was back in 2007 can't remember the exact location). We then spent the whole day walking up and down a street trying to convince homeowners to sign up for a free quote for double glazing, garage conversions and driveway renovations.
Needless to say that I never went back. I did feel sorry for my trainer, as he seemed quite upset that I wasn't going back but the "job" was plain rubbish.
When I went, there were two company names, Executive Advertising and Fosters/Mosco. If they still exist, avoid them at all costs unless you enjoy door to door sales.
