Pros
Honestly...I can't think of any. I've met some nice people, but that's about it. If you're a sociopath and have zero empathy, you might just do well at K.
Cons
Let's start with the greasy 80's sales tactics. They actually teach you to say things like "put er there!" and "whadaya say!" And my favorite "if you act now!" After that, you're taught to barge into the prospects home like a snake oil salesman using two giant bags as battering rams. After they teach you sales tactics that would make Billy Maze roll over in his grave like a rotisserie chicken, they send you hundreds of miles away to leads that would rather spit on you than let you in the door. Management will tell you that they don't cherry pick the leads, but it's funny how only 2 or 3 people on the sales team actually make money while the turnover rate is in the stratosphere. Cherry pick the good leads and give the short timers the crap...makes sense to me. Twice in one week I was sent to appointments where the prospect lived in a nursing home. I've been sent to siding appointments where the home is solid brick and the owner has zero recollection of ever making an appointment. As mentioned in other reviews, a lot of the appointments are for people with no job and no money. I've been to single wide trailers where the telemarketer told the prospect the government would pay for their windows just so they could set the appointment and get an extra 10 bucks on their check. This all sounds terribly negative, but I speak the truth. I'm broke, my car is jacked, I have an ulcer and I owe K over a grand in draws. Unless you are a blood relative to Joseph Stalin or Mao Zedong... Run away from K as fast as you can.
