None, besides maybe whatever having another job listed on your resume would do.
Svantaggi
I would second the other negative review word for word. Everything he or she wrote was spot-on. The building this company is in, the look of the actual lobby, offices, and insistence on "business professional" attire is all a front for what you are actually hired to do: go door to door trying to sell people a different type of service that they already have.
Your average day begins with putting on a suit, going into the office, taking off your suit, and putting on a shirt with the logo of whatever service provider you're going to be representing that day. You drive to a location and then walk door to door, ringing the bell and reciting a sales pitch over and over again to people who do not want to have anything to do with you. You're coached on when to make eye contact, when to look away, when to act like you're writing something, etc. It's all so phony and you constantly feel like you're taking advantage of people. Many customers want nothing to do with you, insult you, and essentially make you feel sub-human because you're essentially interrupting their time at home with their families. If you have any respect for privacy and not selling people services they already have, you'll lose a little bit of yourself with every house.
