Make the shortlist useful

Choose one to three activities that tell you something different about the work. Avoid selecting several ways of describing the same interest.
For each, write an example you can discuss or a question that would change your understanding of the role.
Keep source task IDs with your notes so you can return to the same description. Do not include private employer or customer information.

The exported worksheet distinguishes the reported task from your own notes. It supports exploration, not a hiring decision or a validated assessment.
