In the Industry, this is known as ‘terminated’ and it happens when based on your responses so far, the Client does not need you to complete the rest of the survey. This is due to one of two reasons, (a) you do not match their specific criteria or (b) they already have enough responses from people similar to you.
Most of the time the Client needs to ask you a few questions before deciding to proceed or terminate. This is called a ‘screener’ and it will always precede the main survey questions.
