The screening test includes questions related to age, gender, family, habits, education, & so on. Most users get rejected after completing this step and are often confused why they weren’t selected. This happens because the user isn’t the target audience of the survey. The whole purpose of the screening test is to find out whether the user belongs to the company's target group. If you don’t belong to a company’s target group, you’ll be rejected. This doesn't mean you should avoid surveys. In fact, you must keep trying, as in a matter of time, you’ll find the right one.
Before joining any survey site, it’s always a good idea to check its supporting countries. By doing this, you’ll get the right surveys and you won’t waste time as well. Though some companies offer surveys for global members, the frequency will be low. So try to join companies belonging to your own country, to receive the right surveys.
Sometimes, people get disqualified because they use a VPN or Adblocker. Though it may not be intentional, many users use them to get access to more surveys. If you’re one of them, avoid using these tools as it won’t help you in any way. In fact, it could lead to a lifetime ban. So be honest, and work on surveys that are applicable to you.
