After joining a survey site, you provide some personal and demographic information, which legitimate survey sites will keep private. That information will be used in choosing participants to take surveys on certain goods and services. If you get selected to take part in a survey, you will be notified through mail to take a short survey to see if your profile suits that survey. When you are deemed qualified, you will be requested to take a longer survey.
You’ll be able to cash out your points either through PayPal or with a gift card. Survey Junkie claims you can get your cash out instantly, but this isn’t necessarily true. In most cases, if you request a payout through PayPal and it can take up to 24 hours, but in most cases it is immediate. Compared to other sites out there, this is a huge advantage.

It’s a very well-known scam. You cash the check, then they ask you to either wire some of that money back to them as some sort of fee or buy something for them and send the item to them. So, you deposit the check, then wire some cash to them thinking that the check you just deposited will cover that. A few days later, after you already send them the money, the check will bounce and the money you send to them will come out of your own account.
