Pros
Great place to take a nap at work. You'll sell as much stuff doing that as you will trying to sell their junky services that do not work and no one wants.
Cons
Extremely tough sell, as all of the services they sell are found free on the internet, contrary to what they tell you. None of the services even work accurately. The market prices and the elevator cash bids are from the previous day. The weather is a joke. One time at the office for example, their weather said no precipitation for the next 3 hours, yet it was probably the fiercest storm I've ever witnessed outside! You get paid peanuts to cold call and strike out every day. The commissions get worse every year. Every person you call is so tired of hearing from DTN that they'll never buy anything. Extremely over hyped and over marketed.
