Pros
Some very nice people to work with and get to know. If you don't like moving around much this job is for you. Sit at a stall and recite a script all day.
Cons
Underdeveloped team leaders, basically do nothing but joke around with each other then police the aisles monitoring your calls on remote headphones. Anybody can do the job, but if the people managing you have limited capacity then you have to deal with bad advice that won't improve your sales, and eventually you just concede.
Also- beware of some hiring bait and switch practices: You may not be told in the interview that weekends are required, holidays are required too. They don't close for Christmas, Thanksgiving, etc. That's just greedy. On the hiring website it says paid holidays. Nope, not for phone sales...that's for the managers. You work holidays.
