There are 2 reasons for not qualifying in a survey.
Not fitting the client's ideal demographic profile.
Failing the quality questions in place to determine the consistency of your answers.
Typically, each survey starts with qualification questions and continues with quality check questions to ensure that you are eligible for the study. In some instances, the client's survey contains its own set of qualifying/quality check questions, as a result, there will be instances where you are disqualified at the beginning, middle, or almost at the end of a survey.
We make every effort to decide whether you are eligible or not as soon as possible, however, there may be times when your participation is interrupted or terminated before your responses are successfully submitted.
