This place is legitimate. If you qualify and you go in for a market research focus group, you get paid cash money. One time I got like $200 for 2.5 hours. It all depends on who their customer is. They do not call your number unless someone from your number solicits them.
The call is from a legitimate business venture. You get paid up to $200 for a few hours of taking a survey. They do appear professional as well. Had to hang up though. Got the call during a class lecture.
This is a real company called Fieldwork Dallas. I've done 3 studies for them over the years. They called again today to see if I wanted to participate in one again, and that's how I found this website. If these people call, they're offering real market research studies for either a gift card or a check.
This is Fieldwork Dallas, a company that you sign up with online to take surveys from. They then pay you several hundred dollars for a couple hours of your time. I wish they would call me more. Definitely not spam or a scam.
