The time wasted trying to qualify for tests does not receive compensation. Unfortunately this means that UserTesting is an incredibly inefficient use of time. I have been active with UserTesting for a year and a half now. In that time I have only qualified for TWO tests. When I did those TWO tests all went smoothly and payment was prompt. Every other time a "screener" has disqualified me based on questions that have already been answered as part of my user profile. UserTesting needs to either pay a small sum for taking the screeners or have a better filter so that test screeners for which a reviewer does not qualify will not end up in the inbox.
