Telemarketers attempt to sell products to large segments of the population over the phone. Many people are irritated by telemarketers. Telemarketers often use headsets so their hands are free to operate a computer. Telemarketing is one of the most controversial types of marketing.
One great thing about telemarketing is that they do pay you an hourly wage, plus commision if you sell things. I do direct sales, and I don't get paid until I sell. My advantage is that I work with most of the people face to face, and I can talk to friends, family, and coworkers to help me find leads. Telemarketing is all luck of which numbers you are assigned to.
