Common login is an alternative scheduling method additional to bulk data upload or adding individually.
All the tests arranged by common login will have the same user name and password.

The system will require users to restrict the number of attempts, and mark the candidates' identity through security questions.

This method is often used in the scenario of open invitation. For example, if there is no clear candidate list for some positions, you can release test credentials and invitations on public platforms and the prospective candidates can take the test directly and calculate the result.
