We find question banks can be a bit of a double-edged sword. It's great that you get to quickly add questions to an assessment, but often these questions don't work together well as they're written at different levels of detail.
So, we don't provide a bank of questions.
Instead, we provide a best practice template as a starting point for your assessment - you can then add, remove or change your own questions using the online designer.
You can see this in action in this quick video on how to edit the 360 feedback questionnaire..
